I'm not using a new enough qemu to have that and it doesn't appear in
a released version, but I'll test again once w...

[PATCH v2v] v2v: Set the number of vCPUs to same as host number of pCPUs.
So it didn't make any noticable difference in my test. I wonder if
the test guest I'm using (Fedora 32 using dracut) doesn't use parallel
compression?
However I don't think it can cause a problem and it seems obvious that
it could benefit some cases.

Do you do anything special to optimize storage ? If the thing using
parallel CPUs in the guest is doing I/O you'd likely want to tune
storage at same time. In current QEMU git master there's a change[1]
that sets viort-blk/virtio-scsi num_queues to match SMP count,
so the guest OS get fully parallel I/O from meach guest CPU.
