[Xen-devel] [PATCH] Add maxvcpu support

[Michal Novotny <minovotn@xxxxxxxxxx>]

Hi,
this is patch to add maxvcpus support to xen xm command. It's using 
vcpu_avail bitmask and sets the number of vcpus to maxvcpus if present. 
If it's not present, old behavior is preserved.
In domain config file you can define it as follows:

 maxvcpus = 4
 vcpus = 2

this automatically sets vcpus to 4 and corresponding bitmask to present 
2 vcpus in the guest with option to increase it up to 4 vcpus. If 
maxvcpus is not present, the old behavior for vcpus is preserved.
Thanks,
Michal
