• Advice on how best to configure the network adapters and virtual switch in ESX host

  I'm new to VMware and am its implementation.  I got my training a few weeks ago, and now I'm configing my hosts.  I have 3 guests, each have 2 network cards.  There is a virtual switch that ESX creates when it is installed (vSwtich0).  The books said that it is advisable to delete the VM network port of virtual machine that is assigned to the value group default virtual switch and put it on another virtual switch so that you keep your management network separated from the network of the vm for performance and security.  If I do this, all my virtual machines will have to go to 1 NIC b/c I only have 2 NICs per host.  I thought that I have just to keep all my groups of ports on the default vSwitch0 and add my second NETWORK adapter so that I can take advantage of the Association of NICs for redundancy and load balancing.  However, I'm not sure on the performance and the security risks.  Do you have any ideas or advice?  I could also create two virtual switches and put my virtual machines on one which would have a NETWORK card dedicated and put my service and Kernal VM console on another virtual switch with a dedicated network card.  However, in this scenario, I have no fault tolerance or load balancing.  We are a small shop and we have about 10-15 VMs on each host.  I don't have access to b/c distributed switching we paid only for the company (not more).  Thank you.

  Hi and welcome to the forums,

  With 10-15 VMs per box and I guess that I would seriously consider adding two extra cards for each host in the production machines. You could then do something like:

  vSwitch0 - vmnic0, vmnic2, vmnic3 - Console of Service, VM LAN network

  vSwitch1 - vmnic1 - VMkernel

  That would give you redundancy and performance to access your hosts (SC) and also for all your virtual machines. The VMkernel would get a NETWORK card dedicated for vMotion and could be on a separate network. He didn't need redundancy really as if the NIC sank the only issue is that you cannot vmotion virtual machines. In this case you would just move one of the NIC workgroup through to those switches manually.

  If you only have 2 network cards, then I would say having a vSwitch with two attached network adapters and VLAN the VMkernel may be off. I want absolutely to the redundancy of having two cards together.

  Hope this helps,

• Error: Running VMware ESX in a virtual machine requires the external virtual machine

  We are running ESX Vmware 5 on a virtual test in ESX 4.x environment and machine unable to start the virtual machine on Vmware ESX 5. with the following error.

  Error: -.

  Running on a virtual machine VMware ESX requires the external virtual machine is configured to run a VMware ESX guest operating system. You can not power on a virtual machine until the external virtual machine is reconfigured.

  We found after KB

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1030283

  Howerver, I'm not able to find the option

  1. Select the virtual machine that is running ESX.
  2. Go in VM > Settings.
  3. Click the Options tab.
  4. Select the General settings.
  5. Under Guest operating system , select VMware ESX.
  6. Click OK.

  We are not able to find this option in ESX 4, so we can run this VM.

  Please help urgently...

  Kind regards

  The log file looks good now.  However, it seems that ESX 4.0 is older than I remembered.  Please, add the following line to your ESX VM configuration file and try again:

• Can not pass traffic with label of vmware virtual switch fabric 10 GB

  Hello

  I need to understand how to move traffic labeled VMware VST to these virtual Fabric switch. Blades IBM HS22 connecting internally to the virtual switch between ports 1 to 14. I use 2 external ports (17-18), one connects to the Netgear switch and another to the other switch to virtual fabric. Did the same on the other virtual fabric switch. My Synology rackstation is configured with LUN iscsi that connect to the Netgear switch and I would like to connect my HS 22 rackstation blades. My main concern is that I can't ping the IP of netgear on the same interface vlan. I can ping my Synology diskstation to the netgear which are in the same vlan. NETGEAR and BNT switches are connected by cables DAC SFP +.

  

  Even VLAN is also configured on Netgear switch. The default pvid is set as 1 on all interfaces, can I disable this? Do I need to use tagpvid-penetration on all interfaces.

  Yes. Finally managed to do work. Tagged traffic now connects blades with ESXI 5.5 U2 to the Synology rackstation.

• A Question about VM traffic through a virtual switch

  I have a question please. I though I read somewhere that if you have 2 virtual machines on the same host ESXi and they are on the same VLAN, when these virtual machines want to talk to each other that they don't let the ESXi host through physical network cards.

  Now, I read in the documentation which is only correct if the virtual network, they are on doesn't have an attached physical network adapter. In other words, you create a group of uplink / Port without an attached physical network adapter.

  So, since I'm using a distributed switch and say I have a Port named Phoung(VLAN 2) group that has an attached physical network adapter. Now I have 2 virtual machines on the same host ESXi on this VLAN and when they talk to each other the traffic will remain in the ESXi host, or will still be out of the physical network to the network card and come back.

  Read various documents on this subject has me a little confused. Thank you very much.

  Where did you read that the traffic will leave the virtual switch?

  If I have something miss me the traffic leaves the host if either the virtual machine is on different subnets (i.e. need to delivery), or if they are on different virtual switches.

• VMware Player uses a virtual switch or hub?

  I develop custom computer technical training and must be able to capture the packets network between multiple virtual machines.

  Microsoft's Hyper-V product implements a true virtual switch, so I don't see not all packets that are not addressed to the virtual machine that is running the sniffer of packets on.  Enabling promiscuous mode does not benefit me anything.

  If I switch to VMware Player, I would be able to see all the packets through the virtual network?

  Thanks in advance,

  Jesse

  Product documentation VMware generally uses the term virtual spend however they are not the real switches and should really be called a virtual hub.

• Questions of VLAN to the ESX virtual machine

  Guys,

  We run ESX on a R710 with 4 network ports and two virtual servers that it contains.

  We want a server VLAN 1 re-branded and the other to VLAN 2 from the actuall switch. Only problem is there is room for 1 VLAN because all of our physical network cards are already used. Here's the brerakdown.

  vmNIC 0 is for the management port (1 nic physical)

  vmNIC 1 is for VMS (1 nic physical)

  vmNIC 2 & 3 is for the iSCSI network (NIC physical 2)

  So you can see we have not more physical NIC left to assing one of these virtual machines to a VLAN different

  Any ideas? I created a virtual switch, but we of course no physical NIC to attach to it. When I tried to add the existing virtual machien nic, he warned me that the virtual machines will be moved to it. A little confusing, but how do I get this other server on one VLAN different?

  If you enter just one ID VLAN on the parameters of port group ESX will mark all frames leaving the portgroup with a small (4 bytes) 'tag' indicating the id VLAN. This tag will then be analyzed by the physical switch will then understand what VLAN, this framework needs to be sent in.

  However, the switch must be configured to accept incoming frames with certain tags. If this is not the case, most of the switches will drop frames with identification tags VLAN strangers.

• Is it possible to switch between level of datacenter in VMware ESX?

  Suppose I have a site US and others a United Kingdom so is possible that I can my American site failover to the United Kingdom at the time of the disater? This is possible in VMware ESX at the WAN level or data center?

  Thank you

  Pitoux

  VCS at the level comments or MSCS at the level of the comments will get your failover, but that would require your ethernet network to span multiple sites.  Not always very convenient, especially if you talk about the United States and the United Kingdom

  I guess then that instead of failover, you mean that the DR or continuity of operations.  That, as noted above, would require some kind of replication and backup/restore, your recovery time objectives and your recovery point objective.   All what you can do to get your vm data store blocks in one data center to another.

• How to restore a distributed virtual switch.

  Hello

  I have a question where one of my esx host 4 i crashed and then we rebuild the host vmware and I have the backup of the file esx.conf with me since the day before. I had a virtual switch distributed in the vmware environment, and since I rebooted the backup config that my vcenter does not add the host esx to the distributed virtual switch.

  -How to restore the vswitch distributed on the esxi host settings.

  -When I look on the esxi configuration host configuration file indicates that DVS information are uploaded but vcenter does not overwrite the new settings.

  troubleshooting performed up to now

  I restarted the vcenter and all services and same problem.

  forced file configuration several times and same question

  has taken the esx host that out of the inventory and the same issue.

  any other suggestions.

  The answer to this has been found in Vcenter 5.1 where there is an option to save the DV switch. I connected this bug a few years back with vmware and this problem is fixed in vcenter 5.1.

• behavior of vSwitch in Virtual Switch Tagging (VST mode)

  Hello

  I have a problem with a vSwitch within an ESX 4 environment.

  On my vSwitch is a virtual network, where the port group has been linked to a defined VLANID, so for a real-world scenario, a physical switch has a port configured in access with a predefined VLANID 8021q mode.

  In my scenario the port configured in this way can receive frames already labeled (the generic behavior is that the port receives the unmarked frames). An access of a switch port generally accepts executives 8021 consistent q If the vlanID is the same as configured in its behavior (t - it - Cisco http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/configuration/guide/cli_rel_4_0_1a/AccessTrunk.html), otherwise the switch removes them.

  VMware says this:

  "Switch ports group virtual tags all outbound frames and removes the tags for all incoming frames." It also ensures that the frames on a VLAN do not leak in one VLAN different. »

  OK I agree with this, but if the virtual switch receives a frame already tagged (with the right tag) must be just to not let him down, as Cisco?

  The switch ports group virtual tags all outbound frames and removes the tags for all incoming frames. It also ensures that the frames on a VLAN do not leak in one VLAN different.

  Now, I also checked the actions for the ordinary vSwitch:

  A virtual machine sends frames unmarked on a portgroup with a specified VLAN id (for example, 300) = works

  A virtual machine sends tagged frames (VLAN 300) on a portgroup with the same VLAN id specified (for example, 300) = failed

  A virtual machine is sending of tagged frames (for example, 300) on a portgroup with VLAN 4095 specified = works

  A virtual machine sends frames unmarked on a portgroup with VLAN 4095 specified = fail

  If the vSwitch behavior is very similar to the distributed vSwitch, that it does not accept any marking made by the virtual machine in regular trade, even if it is the VLAN correct. If affecting portgroup VLAN 4095 it throws frames marked, very likely because we cannot specify any "VLAN native. I think that's the answer to your original question.

• Segments of network & virtual switches

  Hello. I have a question on the Association of the physical NIC ports to a virtual switch.                                                                                I have two network segments. The first has a group of VLAN ID. The second has a network isolated from the VLAN ID to evoke. Can I combine the physical NETWORK adapter ports that are connected by physical switches on the two network segments, on the same virtual switch defined in VMware ESX 3.5 / vSphere? I guess I'd better associate the two network segments with two virtual switches, but I'd like to hear from you.

  Thanks in advance for your help

  If you cannot physically route between the two segments then you can create exchanges on a vswitch and have dedicated NICs for each group of ports and plug the network adapters in the relevant physical switches that connect to network segments or if total isolation is necessary, then create a separate vswitch and do the same thing...

• VMWare ESX Server training

  Hello experts,
  I'm new to vitrualization.
  I installed vmware workastation v 7.0 and I also have VMWare ESX Server training Trainsignal dvd for training so here are my questions:

  Can I install VMware vSphere Hypervisor 3.5 on my VMWare Workstation 7.0 for training v?

  Is - this VMWare vSphere Hypervisor 3.5 product different from VMWare ESX Server 3.5?

  I'm you ask all these questions because I want to be sure I can complete a training with VMWare vSphere Hypervisor 3.5 suite drive of my Trainsignal VMWare ESX Server 3 and because I am not allowed to download the evaluation version on VMWare ESX Server 3 and because the VMWare customer service could not answer my simple question and quoted me to the community by them to get advice.

  Thanks in advance for your help and advice.

  Hi nasolsi,

  Can I install VMware vSphere Hypervisor 5 straight on my VMWare Workstation 7 training without affecting my HDD physical whole?

  Yes, it has nothing to do with your actual score and highlights form the part of space, he took from your partition to create the disk of the virtual machine. So basically it will eat the space in the physical partition but does nothing else like the formatting of the entire disk.
  

  
  

  and the performance on my PC?

  No, this will not affect your PC's performance as the workstation will run the pages of RAM and cycles on your physical PC hardware microprocessor.

  
  

  If permitted increase RAM by a value so that you do not encounter CMTF or any other problem. 2048MB is the minimum memory required to run ESXi.

• Use virtual servers to ESX 3.5 in ESXi 5.0

  Hello everyone

  First of all, sorry for my bad English. It is not my language.

  So, I have a question. For the moment, let's have an ESX 3.5 Server 2 virtual servers. (Windows Server 2003)

  Now, we want to improve our ESX 3.5 to 5.0 ESXi. We bought a new server on which we want to run ESXi 5.0. So is it possible to simply copy these virtual machines in ESX 3.5 to 5.0 ESXi? (Updated the vmTools) Or I need to reinstall all of these machines?

  Best regards

  Dominik

  Welcome to the community...

  The new host (ESXi 5.0) is going to be autonomous? If so, you can use Vmware Converter to import the virtual machine to the new host ESXi 5.0

  If you have the shared storage and assign to 5.0 ESXi host, you can remvoe the virtual of ESX 3.5 machine and it add new virtual host, VMtools upgrade equipment, etc...

  You need to remove hidden devices that you are moving to new hardware.

• How to leave the virtual switch as a physical switch law in esxi 5?

  Hello.

  I have Esxi5 installed on a server with 3 physical network card (they are supported and found in Esxi) on that Esxi I installed a virtual-SIN (NexentaStor) machine. The first network adapter is connected to the router, the second network adapter is connected to a PC. DHCP is enabled on the router. Normally on a real switch all connected pc should automatically get an IP address from the server (router), or must be able to communicate when they have a fixed IP address. This does not work on the virtual switch. One of my virtual pc Gets an IP address in a range of false, and I can't connect a real PC at this switch

  2 questions:

  1. Should what settings I use in esxi5 to get virtual pc the good IP address?
     
  2. Is it possible to connect a real pc directly to the second NIC in my esxi server and use the virtual switch as a true switch? In this way, I can use the Gigabit Nic for a fast and direct connection to the virtual NAS and can connect to the internet via the switch?
     

  

  Any help would be appreciated
