[libvirt] [PATCH] virsh: Fix docs for "virsh setmaxmem"



The docs assumed the command works always for QEMU and other
hypervisors. Unfortunately until qemu will add memory hotplug
this can't be done. Fix the docs to mention this limitation.

 =item B<setmaxmem> I<domain> B<size> [[I<--config>] [I<--live>] |
 [I<--current>]]

 Change the maximum memory allocation limit for a guest domain.
 If I<--live> is specified, affect a running guest.
 If I<--config> is specified, affect the next boot of a persistent guest.
 If I<--current> is specified, affect the current guest state.
 Both I<--live> and I<--config> flags may be given, but I<--current> is
 exclusive. If no flag is specified, behavior is different depending
 on hypervisor.

-This command works for at least the Xen, QEMU/KVM and vSphere/ESX hypervisors.
+Some hypervisors such as QEMU/KVM don't support live changes (especially
+increasing) of the maximum memory limit.

 I<size> is a scaled integer (see B<NOTES> above); it defaults to kibibytes
 (blocks of 1024 bytes) unless you provide a suffix (and the older option
 name I<--kilobytes> is available as a deprecated synonym) .  Libvirt rounds
 up to the nearest kibibyte.  Some hypervisors require a larger granularity
 than KiB, and requests that are not an even multiple will be rounded up.
 For example, vSphere/ESX rounds the parameter up to mebibytes (1024 kibibytes).
