Subject: [PATCH] detect-virt: dmi: look for KVM
1abbee
1abbee
Some guests (ARM, AArch64, x86-RHEL) have 'KVM' in the product name.
1abbee
Look for that first in order to more precisely report "kvm" when
1abbee
detecting a QEMU/KVM guest. Without this patch we report "qemu",
1abbee
even if KVM acceleration is in use on ARM/AArch64 guests.
1abbee
1abbee
I've only tested a backported version of this and the previous
1abbee
patch on an AArch64 guest (which worked). Of course it would be
1abbee
nice to get regression testing on all guest types that depend on
1abbee
dmi done.
