Does it supported on never libvirt? How can i solve the issue? I'm use
raw format for disk.
If you insist on using --live you also have to specify --memspec to
point to a location where the memory snapshot is saved. Btw, --live and
--disk-only are basically mutually exclusive since --disk-only implies
that the memory state should not be saved, whereas --live is used when
the memory state is saved.
Additionally a disk-only snapshot is always considered "live" since it
usually doesn't require pausing of the VM.
