[libvirt] [PATCH 1/2] qemu: process: SEV: Assume libDir to be the directory to create files in

[Erik Skultety]

Since SEV operates on a per domain basis, it's very likely that all
SEV launch-related data will be created under
/var/lib/libvirt/qemu/<domain_name>. Therefore, when calling into
qemuProcessSEVCreateFile we can assume @libDir as the directory prefix
rather than passing it explicitly.
