Re: [Xen-users] Live VM migration

[Payal Shah <payals@xxxxxxxxx>]

Hello ,

Thank you for the reply. I got the results I was expecting.

I had one more question regarding open vSwitch and live VM migration.

Live VM migration requires that both the hosts should be in the same subnet. If the hosts are in different subnets then how can we do live VM migration? Can open vSwitch be used in this scenario?? Or is there any other virtual switch that can route the packets as per the new subnet?

Thank you in advance

On XCP (1.1b, may be in XCP 1.0) there is a note in xensource.log about %% of migration.

And you can do xentrace in dom0 to see all hypercalls (but you must understand what they means to get needed information).

I have two hosts as Xen Server named host A and host B in the same network. A
VM is created on Host A. Host A and B have a shared storage using NFS. While
doing migration from host A to host B, how can I see the memory pages being
migrated.
If I run a small continuous program on the VM residing on host A, will the
migration complete first or the sript running will complete first? How can I
see that data is going in clear text? Is there a tool to see the packets
going through? I tried using wireshark and spanning the ports, but I
couldn't infer much. ANy help on this appreciated. Thank you,
