This bug is probably a duplicate issue as this: https://bugs.launchpad.net/ubuntu/maverick/+source/qemu-kvm/+bug/584048
The problem is with Linux bridging. When adding or removing a MAC address (like for KVM, VirtualBox, or even LXC) then if the bridge changes its MAC, this symptom happens. See comment #60 at the URL above, and also see this: https://www.redhat.com/archives/libvir-list/2010-July/msg00450.html The workaround is to use a MAC address that starts with "fe" (or any high really high number) for your guests. This causes the kernel to default to the hardware MAC for the bridge. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/673705 Title: running guests freeze when a guest is powered down -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
