guest.cpu.mode per guest/vm on the same KVM host

[Lukáš Mrtvý]

Hello,
Is possible somehow to set guest.cpu.mode per guest ( VM ) ? I would like
to create on the same KVM host VM with guest.cpu.mode=host-passthrough and
a second VM without any passthrough. Is it possible or this setting is
global / per KVM host? Thanks
