• Isolate virtual networks in vCenter in a network environment

  Hello

  I am trying to isolate a group of vlan was in vCenter in a network environment. I currently have 10 assigned resource pools with different vlan id (350-360). This network environment includes several Cisco 3750 switches configured for connections. 2 VLAN separate were created on the switches to prevent access to two separate places in our building (VLAN 50 and 60).

  The objective here is to limit access to 5 pools of resources to a single office. That means that 5 resource pools (including 100 vm) can only be accessed from a desktop and not the other. The Cisco switch in this office has been configured for vlan traffic through 60 only, but is still not isolate traffic for vlan 50.

  My question: are there additional changes that must be made in the Network Configuration file in vCenter or what I need to make additional configuration changes to my Cisco 3750 switches?

  Any help/advice would be appreciated!

  It's my rating based on p16 and vSphere Networking Guide 5.1 p12. I think about it every now and then. Assuming you are using VST (Virtual Switch Tagging) config, you must ensure that

  1 MV in 5 of the pools you want isolated is mapped to the correct port groups (corresponding to the vlan 50 and 60)

  2 master the correct uplink port on vSS/vDS and physical switch. An easy way is located to 4095, but for security reasons I am generally hosting only VLANs in use.

  3. of physical switch you trunk between edge and core and allow some VLAN specific (e.g. the vlan 50 or 60) on a different port on the switch to edge to hang on your office.

  Hope this helps

  

• VCenter shows a network for a virtual machine that is not associated with any host

  I have a win2k3 VM who at one point had a network assigned to him called "MONITORING".  This network is configured is no longer in the ESXi (5.5) environment.  The virtual machine is connected to a network called "PRD-SURVEILLANCE" which is correct.  It's not really cause a problem, but I can't find a way to get rid of the object of MONITORING network.

  In VCenter MONITORING networks has a VM of 1 meter, the number of hosts of 0.  I also see it in the VM - dialog box, change the settings, but there is no option to remove it.  Profile Image to the virtual machine is version 10 so I can't use the old Client of VI to try to remove it.  I have checked each host and do not see this listed network object.

  I tried to restart the VM, it migration between hosts, changing its network of SURVEILLANCE of PRD to another network and vice versa and close - remove NIC and add a new card network.  MONITORING legacy network still appears in the config.

  For the virtual machine's .vmx file shows that the correct network: ethernet0.networkName = 'RDP-ANALYSIS '.

  Any suggestions on how I can remove the artifact of MONITORING network?

  The virtual machine has a preview that was created at the time where the MONITORING network was still affected?

• vCenter 5.1 - network problem between the host computers

  vCenter 5.1

  (2) the hosts running esxi 5.1

  I have VM in a single dvSwitch and dvPortGroup on two hosts - VM total 5.

  This is where it gets weird:

  -all VM on host1 can ping/browse all VM on host2

  -VM on host2 can ping/browse all * EXCEPT ONE * VM on host1.

  -All virtual machines can ping Bridge and beyond

  Otherwise said - VM1 on host 1 may VM3 and VM2 host2 ping, but VM3 and VM2 cannot ping VM1.

  No firewall or anything like that in the guests, because VM4 on host1 * CAN * ping VM1.

  Looks like an arp or vNetwork question.

  Thoughts, known problems?

  Found!

  I got 2 ports not tagged in the VLAN for switch problems.

  While everything went on-site in the configurations, hard links to the switch are the root cause.

  Thanks for your comments - he has led me on the way to finally discover the question.

• [vCenter 5] Partitioned network concept

  Hi all

  I am in trouble: I'm just trying to understand the partitioned network!
  1 cluster, 4 ESXi 5.0, 4 VM, 2 heartbeat data warehouses.
  Everything is OK: 1 master, 3 slave, 4 VM 'protected '.
  (Mon test: sur l'hôte 1 esclave, je suis réseau débranché mgmt: vSphere HA État: «Connected (esclave) ') "to"Partitioned"(I can RTC in the fdm.log on Master, data warehouses Heartbeat works)... but after a few seconds, he changed his State for 'isolated '.
  Why? Host is still alive via Heartbeat data warehouses ("[ClusterDatastore::UpdateSlaveHeartbeats] (VMFS) ' host-121 @ 9 c: 8e:99:28:6f:c0 is ALIVE '")
  The host must not remain in the State "partitioned"?
  (I read the vSphere 5.0 high availability Deep Dive)
  Thanks for your help
  Concerning

  No, a host can really be partitioned in this case, it will stay in "partitioned" State This can happen, for example, if you have a cluster extended - if the network connection between the 2 sites goes down, while there will be 2 sets of the cluster hosts that can communicate with each other, but not with hosts on the other site. No host is isolated, but each site is separated from the other. In this case, each partition will elect its own master and each master will be guests in the other partition as "partitioned". When the network connection is facing upward, a master will be "abdicating" and become a slave to the other.

• Need router and switches for simple network tips...

  I have to get a new router and switch to an office with 9 computers, 1 printer, and a server.  They are all Mac computers. Two Mac computers are running Windows XP through Parrallels (not sure if it matters).  All computers have just need access to the Internet (through the router), access to the printer and 5 of them on the server.  A few more important details: the router will be located about a quarter of a mile away (where we could get a broadband Internet access) but will have a fiber optic cable running to the office, where will be the selector. In the building off site where the router, we would like to have a backup disk to send important files at the end of each day (or set up to do this automatically later).  The optical fiber has capacity of the card.  We want that the router must be connected only (wireless).  Any suggestion that router and switch combo would be enough?  Thank you!

  You can use a RVS4400 router that has a gigabit capacity with 4 ports, connected to the gigabit switch.

• Cannot add host ESXi 5.5 to vCenter for a routed network - cannot communicate with the specified host

  I was wondering if anyone has come across this problem before, who could give advice how to fix them:

  Host of pre-production UCS ESXi migration of a Production vCenter on another network (routing in place)

  Can ping both directions successfully - from vCenter Prod to the host of the pre-production

  no firewall between the two.

  902 port is open on the host

  Host connects to the pre-production vCenter on the subnet even fine

  VCenter production can add different hosts on the same network end

  Even with the various guests of ESXi UCS.

  ESXi host was completely disconnected and removed from vCenter inherited before attempting to add. No dvswitch physical or virtual.

  Then try and add, enter the user name and password and get cannot communicate with the specified host.

  Thank you

  The solution to this. Used ESX host 5.5 3B (3248547) update that disables SSLv3. (Ref: VMware ESXi 5.5 updated Notes version 3B) one of the consequences of this is that older versions of vCenter (such as trying to move the host) can not add/connect host.

  Enable SSLv3 to spend (port 443) on the resolved host (virtuallyPeculiar: connection A ESXi 5.5 U3b host to vCenter with a lower Version A.)

  Note: should not enable SSLv3 to Port 902.

  Ref:

  The SSLv3 Protocol on vSphere 5.x configuration (2139396) | VMware KB

  Many thanks to Suhas Savkoor of virtuallyPeculiar for resolution for this on his website display

• ESXi 4.1 Update 1 and material update 4 to 7 cards of network breaks vCenter.

  I installed ESXi 4.1 update 01 on 2 servers.  Then I updated the hardware version of all servers in version 4 to 7.  Now the vCenter has no network adapters!  Research in the Windows Device Manager indicates Intel E1000 adapters with a yellow exclaimation point.  Try updating the drivers doesn't produce a message that says that the drivers are up to date.  All other Windows servers work correctly with their network cards, just the Windows 2008 R2 64-bit vCenter server is not able to connect to a network.

  Hope someone has an answer.  Called VMware support, but they will call back within 8 hours.

  You can check 'NIC hidden' and then delete them if they exist as described in article 1179 KB.

• Rear tipping VMs without crushing the production data.

  Hi all

  
  

  I'm new with SRM and I intend to conduct a test of DR with for a specific production with 9 virtual server environment. After recovery, we will have a functional validation of request which will be performed by the owner of the application and some key users, then we will need the application failover to our production data center and we are struggling to find a way to switch back without crushing the production data. Is there any function on SRM 5.0 will it restore servers in the original RPO and throw the chages on the recovering site? I did some research and I found that we can that beside SAN taking a glance of the original LUN before beginning recovery.

  
  

  Thank you very much!!!

  
  

  VMworld 2013... see you there!

  In the recovery plan settings, you can configure a portgroup to test purposes. Just point it to your production network, and SRM will be connect virtual machines instead of a bubble.

  Another possible solution would be to use a VLAN not routable separated for testing on the DR site.

  VMs will be powered on the DR site, while Production virtual machines will continue to function), after the validation tests are above, SRM will clean up and you're done.

  For example, you use the scenario of 'native' test of SRM and you don't have to worry about your production site data.

  The downside of this approach, it is how provide you users access to test environment (Console VM via vCenter / networking tips).

  In addition, the question is if your application depends on other servers that are not connected to the test VLAN.

• "Limited connection" when you configure the network between two computers XP.

  Original title: Configuration of the network connection

  Trying to establish a network connection between two home PCs., both running Windows XP Pro. Have been through the network on both PC Setup Wizard but, they still say limited, in fact no connection. I use an Ethernet cable between the two Crusader. If it is true what I'm doing wrong?

  Thanx Terry

  Old but good, networking tips from MVP Malke, MS:

  The best and simplest is to buy a wireless router. This way you get Internet connectivity both machines and the added benefit of security more between you and the Internet. Then you configure your network wireless safely, and then you configure file/printer sharing. Here is information on the implementation of a router and also in networking. It seems long, but don't be intimidated. Setting up a router and the LAN of sharing between two computers takes about 15 minutes.

  The router configuration

  Setting up a router is simple enough. Normally, you run the CD that came with the router and follow the instructions. If you're running Vista, maybe the CD that came with the router does not work; I do not know this. But you can set up the router without the CD. Note that if you have Internet cable for the connection you have just set up the router to DHCP (or there may even be a choice of cable to choose). If you have DSL Internet, you select TRP usually and enter the username and password you selected when you initially set the DSL connection. So:

  1. turn off the power to your cable modem.

  2. attach a cable (usually supplied with the router) course Ethernet cat5e Internet/WAN port of the router to the Ethernet port on the cable modem.

  3. connect the ethernet cable cat5e from the network card in your computer to one of the ports on the router. If you do not have an ethernet cable (because you were using USB), you will need to go to the store and buy a.

  4. turn on the cable modem. After that all the lights are on, turn on the router.

  To configure the router:

   

  Have a computer connected to the router with an ethernet cable. Examples given are for a Linksys router. See the manual of your router or the router mftr's Web site. for the parameters by default if you don't have a Linksys. Open a browser such as Internet Explorer or Firefox and in the address bar type:

  http://192.168.1.1 [Enter] (it is default IP address of the router, which varies from router to router then check your manual)

  This will bring you to the login screen of the router. The default username is blank and the Linksys default password is "admin" without the quotes. Enter this information. You are now in the configuration of the router utility. Your configuration utility may be slightly different from mine.

  Click the Administration link at the top of the page. Enter your new password. MAKE A NOTE SOMEWHERE THAT YOU WILL NOT LOSE. Re-enter the password to confirm it, and then click Save settings at the bottom of the page. The router will reboot and show you the box of connection again. Do not fill in the user name and put it in your new password to enter the configuration utility.

  Now, click on the link wireless at the top of the page. Change the network name (SSID) wireless by default to something, you'll recognize. I suggest that my clients not use their surname as the SSID. For example, you might want to name your network wireless network "CastleAnthrax" or similar.

  Click on save settings and when you get the prompt that your changes were successful, click the wireless security link which is just beside the Basic Wireless Settings link (where you changed your SSID). If you have a newish computer, you will be able to affect security WPA2-Personal Mode. Do this and enter a password. The password is what you enter on all computers that are allowed to connect to the wireless network. MAKE A NOTE SOMEWHERE THAT YOU WILL NOT LOSE.

  At this point, your router is set up and if the computer that you use to configure the router will normally connect wireless, disconnect the Ethernet cable and wireless of the computer should see your new network. Enter the password you created to join the network and start surfing.

  B. file/printer sharing of

  Excellent, comprehensive, but easy to understand article on sharing files/printer under Vista. Contains information about sharing printers and files, and the folders:

  http://TechNet.Microsoft.com/en-us/library/bb727037.aspx

  For XP, start by running the Network Setup Wizard the on all machines (see warning in section A below).

  Problems sharing files between computers on a network are usually caused by 1) a misconfigured firewall or a firewall neglected (including a dynamic firewall in a virtual private network); or (2) inadvertently run two firewalls such as the firewall of Windows and a third-party firewall. and/or (3) do not have accounts to the same users and passwords on all computers in the workgroup. (4) tries to create actions where the operating system does not.

  A. configure the firewall on all machines to allow traffic to local area network (LAN) as being approved. With the Windows Firewall, it means which allows file sharing / print on the Exceptions tab normally run the XP Network Setup Wizard will take care of this for these machines. The only "witch hunt", it will turn on the XPSP2 Windows Firewall. If you are not running a third-party firewall or you have an antivirus with "Internet Worm Protection" (like Norton 2006/07) which acts as a firewall, you're fine.  With a third-party firewall, I usually set up the allocation of LAN with an IP address range. E.g. would be 192.168.1.0 - 192.168.1.254. Obviously you would substitute your correct subnet. Do not run more than one firewall. DON'T STOP FIREWALLS; CONFIGURE THEM CORRECTLY.

  (B) to facilitate the Organization, put all computers in the same workgroup. This is done from the System applet in Control Panel, the computer name tab.

  C. create the counterpart of the user accounts and passwords on all machines. You do not need to be logged into the same account on all machines and assigned to each user account passwords can be different; accounts/passwords just need to exist and to match on all machines. DO NOT NEGLECT TO CREATE PASSWORDS, EVEN IF ONLY OF SIMPLE. If you want a machine to boot directly to the desktop (a particular user account) for convenience, you can do this. The instructions on this link work for XP and Vista:

  Set up Windows to automatically connect (MVP Ramesh) - http://windowsxp.mvps.org/Autologon.htm

  D. Si one or more of the computers is XP Pro or Media Center, turn off Simple file sharing (Folder Options > view tab).

  E. create share as you wish. XP Home does not share the users directory or the Program Files, but you can share folders inside those directories. A better choice is to simply use the Shared Documents folder. See the first link above for more information on Vista sharing.

  F. you have the job of file sharing (and tested by exchanging a file between machines), if you want to share a printer connected locally to one of your computers, share of this machine. Then go to the printer mftr Web site. and download the latest drivers for the correct system. Install them on the target machines. The printer must be collected during the installation procedure. If this isn't the case, install the drivers and then use the Add Printer Wizard. In some cases, printers must be installed as local printers, but it is outside this response.

• Advantages and disadvantages of the use of the same network card to the network management and production (all my virtual machines) VLAN?

  Hello

  I have an ESXi. The management network and the virtual machines vlan through the same network adapter.

  What the disadvantages are to do?

  Can you help me please?

  Thank you in advance,

  Kind regards

  Garish

  Well well, in this case. This is a perfect case of SPOF, try to reach NIC teaming to avoid this.

  At least two cards physical network is necessary in your hardware ESXi host to do.

• Unable to assign the IP of network profiles.

  Hello

  I want to activate the user select network based on the network available, chosen in PG when you set a reservation. I use XML to list outside these exchanges but facing problems with it. I use vCAC 5.2 with vSphere 5.5

  The model is configured with a network adapter, keeping in mind that what ever network selected by the user would add to the provisioned VM.

  1. I am able to get the Port Group reflected in vcenter under the network section, but the setting of the virtual machine does not added adapter list. I could see Mac address associated to the Portgroup and allocated IP network profile, but I do not see these values in the VM.

  2 - I custom configured VM from vCAC and added additional NIC with different portgroup who also has associated the different subnet network profile. This time I could see port group reflected in vCenter under network and also the adapter is also added to the VM, but still could not see IP address other APIPA address then. However a single IP address again responsibility network profiles that does not matter where in the VM.

  have I missed something? is there an agent that must be installed on a virtual computer to enable this feature (just a wild guess! )

  Help, please!

  BR,

  MG

  Yes this actually solved the problem, but it's still strange that we need to care about customization in vCenter and reference should be placed in the strategic plan, how construction profile Important in this scenario?

  However, custom, property of "CloneSpec" is not required to mention under properties if you use the field 'customization Specs"of Blueprint.

  This requires no installation of the Agent. It is agentless.

  Thank you

• Requirements of ports for vCenter Server 5.1 - SysLog Collector

  Hi all

  Has anyone installed a SysLog collector?

  My book of vmware by Lowe mentions little on the ports for it.

  During the installation of the server, he gave me a list of ports.

  I accepted all the flaws, except that I changed the ports http to 81 and 8081 because IIS is installed (vmware docs say to use one port other than 80, if IIS is already installed)

  Now, during the installation of the SysLog collector it asks which http port I use.

  The vmware docs nothing mentioned on the syslog http port is my book. The vmware for TCP docs show that.

  ESXi Syslog Collector

  8001

  TCP

  ESXi

  vCenter Server

  Network syslog server

  Just use port 81 as the http port I have set up for vcenter server? The web interface won't connect through this port? There will be a conflict?

  I used netstat and port 82 is not used. Should I use?

  The other settings works ok?

  There is no firewall involved; vCenter server and the VMs system will reside on the same site

  Thanks in advance

  port 81, that is according to the third screenshot! 8081 is for Tomcat!

• I fired my off-grid vCenter Server

  Hello everyone,

  I have a 5.1 vcenter server running as a virtual machine (win2k8R2). We have all the virtual machines on distributed switch. I had to upgrade the vnic on vcenter server vm to VMXNET3 E1000. I made a mistake by deleting the existing network card before you add the new network adapter. Now I'm not able to make the VM vcenter on the network. The NETWORK card I added is disconnected and does not see any portgroup who select us in the menu to the bottom to choose the network for the VM.

  I think it's because VDS is managed by vcenter himself and vcenter being out of the network, it does not show the exchanges on VDS that I can connect to.

  All I can think is that I'll have to add a new network adapter on the host and create a VSS and vcenter vm it first add and transfer it to service VDS. But I have no network card now. It is in production

  Suggestions how to add vcenter to VDS?

  Thanks - AG

  Add a NIC temporarily and created a VSS with VM network. Low-pressure vCenter to VSS and then in the properties of the VM, replaced by NIC vDS.

  Thank you all.

• Network lost after restart of host settings

  I have vcenter that works as a virtual machine on host #1 (vsphere 4.1 u1)

  I used vcenter to configure networking on the host #1 and was able to connect to the San and run a virtual machine of the SAN.

  About 10-15 minutes later, I stop the virtual machine of vcenter, put the host in maintenance mode and rebooted the host.

  After startup, the host no longer has network (vswitches, iscsi, config, etc.) settings and as such, cannot see SAN data warehouses.

  I do not understand why this has happened.

  I had already installed 4.1 on my other 2 hosts literally 10 minutes before it happened, and now I have an unpleasant feeling in the pit of my stomach.

  Using ESX or ESXi?

  Because ESXi works in the virtual disk, and it updated the config files not in real time.
