hi,all

this error  is  after launch libvirt's migration API. but this error is common.

a windows guest os which has virtio-device  will fail to migration.

------log of that vm-----------
 features 0x1e unsupported  allowed features  0x71000002
  qemu warning error while loading state for  instance 0x0 of device '0000:00:04.4/virtio-console'

 

do you have some idea about that?

 

thanks
