Re: [libvirt] [PATCH] qemu: blockCopy: Allow shallow block copy into a raw image

It is easy to reproduce. Suppose live guest xml looks like: # virsh dumpxml vm1|grep disk -A 8 <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> <source file='/var/lib/libvirt/images/raw.1430143276'/> <backingStore type='file' index='1'> <format type='raw'/> <source file='/var/lib/libvirt/images/raw.img'/> <backingStore/> </backingStore> <target dev='vda' bus='virtio'/> <alias name='virtio-disk0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </disk> Then try a shallow blockcommit of file has no backing file

But a shallow block copy of file which has backing file into a raw file does not make any sense, right?
