[PATCH 3/4] qemuBlockStorageSourceNeedsStorageSliceLayer: Deal with 'luks' files

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The 'luks' driver in qemu is as any other non-raw format driver and thus
doesn't support the properties for 'slice'. Since libvirt considers
luks files to be raw+encryption we need to special case them when
dealing with the slice.
