Do we need extra text talking about rounding and/or rejection if the
hypervisor can't support a memory limit with that small of a granularity
(for example, Matthias recently posted patches regarding esx only having
megabyte granularity).
Hows this for the setmem virsh text?
setmem domain-id new-allocation
Immediately change the current memory allocation for an active guest domain. The
new-allocation value is in
kilobytes, and will be rejected if the hypervisor can't support the given memory
allocation.
For vSphere/ESX, the new-allocation value must be a multiple of megabytes (ie. 2048
for 2GB), otherwise the
hypervisor will reject it.
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.
