  • 1.  VMotion and Private LAN

    Posted Jun 15, 2011 10:16 AM

    Hi,

    we have two ESXi 4.1 Server with Enterprise Plus Lizense and vCenter.

    Now I have three VMs. One which is a Webserver direct attached to a "real" DMZ Network. The Webserver has a second Networkinterface which provides a private LAN for the other two Servers. An AppServer and an DatabaseServer. When i will put the ESX Host to mantinance vmotion can't move the server till i disconnect the NICs from the private lan. Is there a way to solve this? With a dvswitch? The DMZ LAN is existing on each ESX. Or must i convert this to an dvswitch to?

    It's no problem when the connection breaks for a few seconds. But I don't want the to something manualy on the NICs.

    Thanks for Hints!

    It seems that you are running vSS (Standard Switches) and not Distributed Switches, since you are Enterprise Plus license I'd highly recommend that you configure vDS.

    For the time being, make sure that your switches and port groups names are identical accross all hosts (case sensitive) otherwise, your vMotion will fail.

    Right now i use only standard switches. When i setup a distributet switch for my private lan, must i setup an physical network interface to it? or does it work when i connect the vms to it and the floating over the two esx server?

    is there a good howto somewhere?

    Thanks.

    Below is the vDS migration and configuration guide.

    For the time being to solve your vMotion issue please has consistent switches and PGs across your hosts.

    Take a look at http://kb.vmware.com/kb/1006701 to see whether this could be a solution for you.
