Hello all, I'm trying to create an online internal snapshot to
work with
Cuckoo Sandbox.
I keep receiving this -22 error below on my Ubuntu system and I'm out of
ideas, been at it for a while so any help is appreciated.
root@cuckoo-sec:~# virsh snapshot-create-as cuckoo cuckoo-snap1 "Cuckoo
Snapshot"
error: operation failed: Error -22 while writing VM
That message comes from qemu (file a bug report with them for
poor-quality error message; looks like someone forgot to convert a
negative value back into a positive EINVAL errno value).
As for why qemu is seeing an EINVAL, I have to wonder if it is a case of
AppArmor blocking access to a file. But that's weird, as internal
snapshots don't normally need to open any additional files. At any
rate, it's more likely to be a qemu bug than a libvirt one.
