Uh.. isn't this a dupe of bug 1550136, itself an existing qemu-kvm-ma dupe of bug 1545016? Actually, this problem probably shouldn't even occur on qemu-kvm-ma, since that doesn't support memory hotplug, which is the use case for HPT resizing. In theory you can trigger the bug by manually performing a resize, but I'm assuming that's not something we support. |
