Re: [libvirt] libvirt external snapshot error

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.
So, i'm try to modify command to virsh snapshot-create-as 40219
--no-metadata --disk-only --diskspec sda,file=/test.raw
but also have error:
error: unsupported configuration: external snapshot file for disk sda
already exists and is not a block device: /test.raw
