Re: [libvirt] [PATCH] docs: clarify that virsh setvcpus and setmem only work on active domains

Maybe more like:
Some hypervisors require a larger granularity than kilobytes, and
requests that are not an even multiple will either be rounded down or
rejected.
Heh, nice text. Combining both of your above sounds even better though I
reckon:
setmem domain-id kilobytes
Immediately change the current memory allocation for an active guest domain.
Some hypervisors require a larger granularity than kilobytes, and requests that
are not an even multiple will either be rounded down or rejected. For example,
vSphere/ESX rejects the parameter unless the kB argument is evenly divisible
by 1024 (that is, the kB argument happens to represent megabytes).
For Xen, you can only adjust the memory of a running domain if the domain is
paravirtualized or running the PV balloon driver.
Note, this command only works on active guest domains. To change the memory
allocation for an inactive guest domain, use the virsh edit command to update the
XML <memory> element.
Workable?
