[one-users] Live migration leads to UNKNOWM state

[Stefan Ivanov]

Hello Jaime

Problem is resolved,

After little modification of live migrate scripts everything is fine. The problem is that: checkpoint and deployment file not copied to target node.

Right now I upgrade to 4.6 and test how is live migration I this version.

Thanks and best regards,
Stefan Ivanov

Hi Stefan,

can you verify if after a while the vms reverts back to the RUNNING state.

Can you also manually confirm that the VM is indeed in the target server (by running virsh -c qemu:///system list)

cheers,
Jaime
