libvirt (including virsh) is sponsored by Redhat and developed
separately from Xen. As a result it might not support new Xen features
yet (in this case vcpu_avail).

If your concern is simply "copy latest config overwriting old config",
you can use xm. For example

xm list -l domU_name > domU_name.sxp

It will have entries like this
    (vcpus 8)
    (online_vcpus 1)

The sxp file can be used to create domUs using the usual "xm create".
