Hi, i'm using virsh -c qemu+ssh://test.node/system snapshot-create-as 40083 --no-metadata --disk-only --live –atomic --diskspec sda,file=/test
outputs: error: Operation not supported: live snapshot creation is supported only with external checkpoints

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. Peter
