Hi, Is there a dependency b/n<vcpu> and<topology> ?
There should be, but isn't yet.
Is specifying<vcpu> mandatory for a SMP guest ?
No.
Can't I skip<vcpu> but have<topology sockets= cores= threads=> to define a SMP guest ?
It should be possible, but isn't yet.
I see that if I skip<vcpu>, libvirt generates -smp 1 on qemu command line which results in qemu booting a VM with single CPU irrespective of the topology specified. Shouldn't libvirt arrive at correct CPU count (vcpus=sockets*cores*threads ?) even if vcpu isn't specified rather than defaulting to 1 ?
