problems of network on virtual servers

Hi all


I have vCenter 4.1 and 4 hosts (ESX and ESXi 4.1) with several virtual servers on each host + CF as data store

On each host are switch standard with several networks of vm - all hosts are clustered HA.

On each switch are two nic mode of teamwork.

When I tried to migrate virtual server connectivity (using vMotion) network of virtual servers is one host to another I lost - I unplug the network adapter in the virtual machine settings and connect the back - then all is well again.

I tried to change vm network different network, then again - also helps.

I tried this time migration batch and this problem are in most cases.

In vCenter Evens are no cases on this issue.

I do not understand where to look for problem - suggestions?


Thank you

Marc Alain

There is no newspaper vSwitch, se.  As the vSwitch don't not participate in protocols spanning tree, spanning tree options in general do not import with ESX hosts.  Get your network to hell team all together is generally not welcomed.

PortFast, however, must be activated as posted above.  You will need to make sure portfast is enabled on your access level switch.  If they are in the system blade, then you must ensure portfast is enabled at this level.

After a migration, without portfast, the migrated nic should finally come, and you should be able to see the mac in case address.  Are you able to see it?

  • How to set up/configuration of the network on virtual servers?

    We just bought the license for vSphere with two processors. I will put up at least three virtual servers on that host computer. Can someone point me to an instruction step by step on how to set up the network so that each guest operating system will have their own unique IP address and/or MAC address? The server is an HP Proliant DL380 G7 with two NIC standard more map of the ILO.

    Any suggestion is appreciated.

    MAC address of the virtual machine is generated by ESXi host when you first power on the virtual machine and the IP address will be assigned by an existing DHCP server or you can configure it manually. Regardless of the implementation of a server as a virtual or physical machine, you generally EF static IP settings to a server system.

  • Problem of virtual servers

    Hi all

    I've been going through David Powers yet in a book published on Dreamwever CS5 with PHP, via the site Web of Creative Edge and got the point of creating virtual servers for my sites. I added the following lines to httpd - vhosts.conf as described in the book:

    < directory C:/vhosts >

    Order Deny, allow

    Allow all the

    < / Book >


    and now the Apache won't start not (through the XAMPP Control Panel).  If I remove these lines and Apache starts OK. The error log contains the line:

    "httpd.exe: syntax error on line 484 of the C:/xampp/apache/conf/httpd.conf: syntax error on line 53 of the C:/xampp/apache/conf/extra/httpd-vhosts.conf: / directory > unmatched section < Directory >.

    I've tried a few things (including the passage of the c: / to C:\) but to no avail. The lines of same exact above are also in his previous book, Dreamweaver CS4 with CSS, Ajax, PHP, so it may not be a typing error.

    I'm stuck, any ideas?

    I use Windows 7 Home Premium 64 - bit with XAMPP 1.7.3.

  • RV042 virtual servers?

    Hello.  I'm having a hard time to believe the RV042 router of "class business" may be missing some functionality so that I am simply not see it and someone can point me in the right direction.

    I need port forwarding of set-up to convey a certain external port on a different internal port.  Many router manufacturer call this "virtual servers" differs from "port forwarding", which transmits the number of external port on the same internal port number.

    It is a simple feature that I'm surprised, I'm not.  Even my little router to do this.  Is there another way to do it on this device?

    Unfortunately, I think that the functionality isn't there and that was my only problem with the Linksys devices generally.  They seem to still be close to full functionality, but then leave out an important aspect you need.

    I don't know if that's what you're looking for, but I found the topic UPnP Set Up > the RV042 UPnP. If you click on the button of the service management, you will be asked for the name of the Service, Protocol, External Port Port internal. Here are the instructions I found on the part of the aid.

    1 Select the function in the menu drop-down.
    2. If the Service you need is not in the menu, please click the button of the service management to add the new name of the Service and enter the Protocol,
    Protect external and Internal Port. Click on the add to list button. Then, click on the Save Setting button or click on the Exit button.
    3. Enter the name of host or IP address of the server that you want users to access to, and then activate the entry.
    4. click on the button Add to the list and configure the inputs as much as you like. You can also remove selected application.

  • Can access virtual servers, but not the server host after vpn

    When on the network, I can access the host server and all other virtual servers (virtualized with virtualbox). But when I connect with VPN I have no access to the main server, but I have access to any of the host servers - and I can get access to the main server of one of the host servers.

    Where do I start looking?

    using of 5505 and asa version 8.4 is (2).

    The nat setup is like this:

    3 (inside) (outside) static source any any static destination NETWORK_OBJ_10.10.10.0_28 NETWORK_OBJ_10.10.10.0_28 non-proxy-arp-search to itinerary

    translate_hits = 0, untranslate_hits = 0

    6 (on the outside) to dynamic interface of the NET-VPNPOOL source (outdoor)

    translate_hits = 0, untranslate_hits = 0

    On the host, I see that you have 2 default gateways configured. It can have 1 default gateway, and to the other interface, you must configure static routes for specific access.

    The interface that needs to connect to the Internet should have the configured default gateway. The traffic that pass through the interface of the SAA should also go in and out the same set of interface, IE: If the host server connects to the interface via dmz out to the external interface, the return traffic must also go through this path, apart from the interface and return to the dmz interface.

  • Problems with networking

    Hello

    We have a vmware infrastructure still in version 4 on a HP Blade Center works for a few years without problem.

    However, 2 days ago, we noticed the VMS has been very slow. We have reduced the problem of network connectivity, even if we do not find what is the problem.

    On VMS, if we try to ping another server (inside or outside the confines of the blade), it loses a large number of pings. Ping by the ESX host everything well without loss of ping.

    This happens on all esx servers 4.

    On the other servers blades on the same box (blades not with hypervisor installed), we don't see any problems, and they work very well. The affected only blades are the esx servers.

    No changes were made to the environment that could have an impact on the virtualization servers, nor there was any firmware update, patch or sw in this infrastructure.

    Do you have any suggestions on what this could be and how to perform troubleshooting on this issue?

    Thank you and best regards,

    Hi all

    Thank you for your help. We have already identified the problem. It was a problem with the switches on the blade case. Raise them solved the problem.

    Kind regards

  • Cannot ping between virtual servers on the same host

    I have a 5 ESXi host with 3 virtual copies of Windows Server 2008R2 running on them. The ESXi host is connected to my switch, which has the Windows 2008 R2 DC to my test network and my laptop management with VSphere branch above as well. I can ping host, mobile and ad server of each of the individual virtual servers and can ping and RDP for all 3 from other devices not on that host, but I cannot communicate between the three. I have Windows Firewall disabled on all three. I have no firewall, and all machines have an IP address in the 10.0.0.X range I deleted then recreated the only virtual switch on the host on which appear all 3. I've been VERY frustrated for the last 3 days on it. Why my virtual machine cannot talk to each other?

    When you have registered virtual machines in ESX you selected moved VM or Coiped VM? Go to editing parameters and watch the MAC addresses. My guess is that if you copied power (including the vmx files) then the MAC address is the same for all virtual machines. You can stop the machine and change for a MAC address mac address. You can also remove the network adapters, one of each, and then add the new network cards. Remember to reconfigure the IP addresses on the box and remove the ghost network maps after doing this.

    Check this KB to change the mac address.

    http://KB.VMware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalID=507

    Also, can you connect to the switch and look at the ARP table and see if the system VMs register here.

  • How do I create redundant (or mirrored) virtual servers?

    Here's the senerio:

    I have a server VMWare ESX 4.1.0 6 virtual servers (we'll call this server A server).

    I recently bought a new 4.1.0 ESX Server and it is running 1 VM (we'll call this server server B).

    Server is running out of disk space, while I pass some of these virtual servers to server b (this isn't a problem, I know how to do this)

    My question is:

    1.75 TB of space Server B has 2 stores of data DS1 and DS2 has 930 GB of space

    I want to spend most of the virtual servers of the server A to DS2 on server B then have these updated virtual servers mirrored on DS1 on server B, so that if there is a problem with the server mirroed on DS1 DS2 will take over and continue to run. I also want to reflect that I leave on A DS1 server on server B.

    Is this possible? If so, how should I do? Thank you

  • Problem Pairing device: Bluetooth virtual keyboard (VKB) detection of service failed

    Hi, I could use help to determine the cause and the solution to a problem I have. I want to associate this with my Toshiba Tecra M4-S435 keyboard. The laptop has an internal module installed, "Cambridge Silicon Radio, LMP (V: S) 02:0490." I installed the last 5.10.01 (T) BT stack. I have several other paired devices, but this one is the original questions.

    The unit is in the discovery as a keyboard VKB (it supports HID and SPP); I want to use the HID profile. In the authentication dialog, the VKB beeps, who is his warning that a PIN can be typed into the unit, but to hit the enter key, a dialog box informs me that "Detection of Service Failed". I've seen similar problems posted on the manufacturer's website, but I have not seen any resolution.

    Any help is greatly appreciated.

    Hello

    I m not an expert from BT, but if you have several other devices with your laptop coupled, then everything is ok with your Tecra M4 BT stack and the machine.
    It seems that there is a compatibility problem with your external virtual Bluetooth keyboard.

    Either the Toshiba BT stack does not support this VBK and service or the firmware of this device allows a few worries
    However, in case I would recommend contacting manufacturing virtual Bluetooth keyboard for more details.
    Guys should more known on own products as simple Toshiba here users in the forum.
