view agent unreachable when persistent desktop is vmotion

[JulianAR]

View 4.6;| ESXi 5 | VC. 5

Anyone seen this issue:

Ran into this issue when I put a host in maintenance mode and i vmotion the persistent desktop off the host the view agent goes unreachable in the view admin portal.  And this happens on different VMs based on the same OS W7-64bit-Enterprise

Is it permanently unavailable and after a reboot it comes back OR after vmotion agent comes back after few mins ?

[JulianAR]

it permanently unavailable and after a reset it comes back.  Odd thing when we vmotion it back it agent comes back. 

thanks again for your reply

When you move it and the agent goes offline does the VM still respond to pings?      It could be something on the network side of the host your moving to.

My wild idea - you vmotion and somehow the Physical Network Switch still has the old ARP entries. when you reboot it refreshes those entries and everything works fine. I think this is something to do with networking...

So It may be related to the network side.  So here are some resolution paths I taken to make it work.

Setting ARP to Manual:

Put the Desktop in Maintenance mode

Shutdown the VM

Change Mac Address to Manual: and enter in a static MAC address

Remove Desktop from Maintenance mode

IP Address should now be populated in VIC with new MAC address

Setting ARP back to Automatic:

Put the Desktop in Maintenance mode

Shutdown the VM

Change Mac Address to Automatic

Remove Desktop from Maintenance Mode

VM should now be back to Automatic

Also I used this site: http://rickardnobel.se/vswitch-notify-switches-setting/

Will have to further investigate the root cause.

Thanks for your help guys.
