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