HI,

I have a Q about sharing a vcpu across Vm's (cpu alloc ratio 1.0 and HT not
enabled)?

I have a Use case where a VM needs vcpu's and one of the vcpu is dedicated
to the VM for some traffic processing. We want the other vcpu which is used
for control processing and can be shared with a similar VM's control
processing.
Is this possible and support in openstack/libvirt/KVM?

If so could you please advice how to test it?

Regards,
Bharani..
