[Bug 1658877] [NEW] live migration failed with XenServer as hypervisor

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

I used devstack to deploy a multi compute node test environment with XenServer
Then I executed the command "nova live-migration --block-migrate admin-vm5 ComputeNode3"
Then I got the below errors:
