Description Hollis Blanchard 2009-09-18 14:42:27 EDT
Description of problem:
The memory allocation field of virt-manager is disabled while a KVM guest is running.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Start KVM guest.
2. Run lspci in the guest to verify virtio-balloon device ("00:05.0 RAM memory: Qumranet, Inc. Virtio memory balloon") is present.
3. In virt-manager, click Details tab, then Memory.

Actual results:
Current allocation field is grayed out.

Expected results:
Current allocation field would allow user to change guest memory allocation (triggering balloon action in the guest).

Okay, AFAIK this is fixed in Fedora 12 and the problem in Fedora 11 is some xen specific hack:

  def is_memory_hotplug_capable(self):
   # Running paravirt guests can change it, or any inactive guest
   if self.vm.OSType() == "linux" \
      or self.status() not in [libvirt.VIR_DOMAIN_RUNNING,\
        return True

Cole: feel free to close as fixed in rawhide if you don't think it'd be easy to fix in F11
