Hi ,
I have been banging my head on this for the last 8 hours ... and i really need to know if is really a bug or i am doing something wrong.
Cleaning out my inbox, and I don't think I ever saw a reply to this one.
Description of the problem:
When the virsh setmem command is used to inflate the balloon on a VM to which 8GB of MaxMemory or more are allocated then the information reported with virsh dominfo , virsh dumpxml after the balloon change has been performed are wrong.
It turned out to be a bug in qemu and not libvirt; it has since been fixed for the upcoming qemu 1.5, and will probably be backported to other stable builds (pester your distro to include the fix, if they haven't already).
I am going to raise a ticket on RED HAT bugzilla for this but was hoping to get some feedback here first to avoid raising a ticket for something that maybe i just misunderstood.
Platform is Centos 6.4 (problem was present in 6.3 as well starting with libvirt-0.9.10-21.el6.3.7 )
Then it looks like this bug is relevant to your setup: https://bugzilla.redhat.com/show_bug.cgi?id=927336 -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
