[libvirt PATCH 03/12] cpu_map: No longer ignore vmx- features in sync_qemu_features_i386.py
Some guest OSes require cpu features from the vmx-* family,
e.g. vmx-xsaves. Up to now, libvirt ignored these features as they
were not required yet. qemu does not automatically enable e.g.
"vmx-xsaves" when requesting "xsaves":
qmp="qemu-kvm -machine accel=kvm -nodefaults -nographic -qmp stdio"
$(qmp) <<-EOF | jq | grep "xsaves"
{ "execute": "qmp_capabilities" }
{
"execute": "query-cpu-model-expansion",
"arguments": {
"type": "full",
"model": {
"name": "Skylake-Client-v1",
"props": { "xsaves": true } `# set to "true" or
"false"`
}
}
}
{ "execute": "quit" }
EOF
with xsaves "false":
"xsaves": false,
"vmx-xsaves": false,
with xsaves "true":
"xsaves": true,
"vmx-xsaves": false,
Stop ignoring vmx-* features and begin adding them to libvirt's
database.
