Well, I don't know Keir since the main use scenario for maxvcpus is to
set number of vcpus for the guest so a new definition in Xend should be
required.
We already have a config option for that, called 'vcpus'. 'vcpu_avail' can
then be used to limit the number of those which are brought online during
initial boot. Any new config-file options can be sugar on top of those.

Well, imagine scenario you need to allocate 4 vcpus to the guest but you
need to use only 2 vcpus at startup. So you suggest having `vcpus` and
`maxvcpus` options in the config file and allocating all the `maxvcpus`
and setting number of `vcpus` by setting appropriate mask using
`vcpu_avail` ?
Thanks,
