Hello!
I have a guest with one qcow2 disk image (vda) and one physical
partition (sda) from host. When I'm trying to get snapshot with:
virsh snapshot-create-as .....
It fails with message: error: unsupported configuration: source for
disk 'sda' is not a regular file; refusing to generate external
snapshot name
According to this error message it looks like you are attempting to do
an external snapshot, e.g. by using --disk-only.
This is fortunate because external snapshots can be selected on a per
disk basis:
I understand, that it is not possible to make a snapshot of physical
device, but it is enough for me to take snapshot of vda. How to force
virsh to ignore sda ?
--diskspec sda,snapshot=no
