kvm-hint-dedicated requires host CPU passthrough?

[Stefan Hajnoczi]

Hi,
libvirt refuses to set KVM_HINTS_DEDICATED when the CPU model is not
host-passthrough.

Is there a reason for this limitation?

My understanding is that KVM_HINTS_DEDICATED means the vCPU is pinned to
a host CPU that is not shared with other tasks. Any KVM vCPU should be
able to support this feature, regardless of whether host-passthrough is
used or not.
