[libvirt PATCH 0/5] qemu: support "max" CPU model

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



QEMU has supported a "max" CPU model for many releases now, but somehow
we never got it wired up into libvirt.

"max" is useful for applications which don't care about live migration
and just want the best CPU model possible. Normally "host" would be used
but this only works for KVM. "max" is identical to "host" for KVM, while
for TCG it exposes every feature TCG implements.

This "max" model will be a natural choice for something like libguestfs
and probably other apps too.

In libvirt we enable it with

   <cpu mode="maximum"/>


Daniel P. Berrangé (5):
  conf: define a new "maximum" CPU mode
  conf: add reporting of "maximum" CPU mode in domain caps
  cpu: wire up support for maximum CPU mode
  qemu: probe for "-cpu max" support
  qemu: wire up support for maximum CPU model
