Subject: [PATCH] basic/virt: Detect PowerVM hypervisor
Currently systemd-detect-virt fails to detect running under PowerVM.
Add code to detect PowerVM based on code in util-linux.
Signed-off-by: Michal Suchanek <msuchanek@suse.de>
(cherry picked from commit 3224e38bb6b3287ca253cbafb460a150544d5818)
Resolves: #1937989
