Now, let's do a live blockcopy (with a '--finish' to graecully finish the mirroring):
$ virsh blockcopy --domain testvm2 vda \ /export/dst/copy.qcow2 \ --wait --verbose --finish
Examine the contents of the above 'copy':
$ guestfish --ro -a copy.qcow2 [. . .] ><fs> run ><fs> mount /dev/sda1 / ><fs> ls / bar baz jazz lost+found ><fs> quit
If I'm reading the man page of 'blockcopy' correctly, shouldn't it 'flatten' the entire chain, by also copying the contents of base into copy.qcow2? i.e. the 'copy' should have files (including the file foo from 'base':
foo, bar, baz, jazz
True or false?
