I have the same 4-second bridge freeze when using LXC containers and lxc-start or lxc-stop. (I am using a custom script to create my LXC containers.) I saw the reference to this above:
https://www.redhat.com/archives/libvir-list/2010-July/msg00450.html I changed my custom script from this: MACADDR="00:16:3e:"`head /dev/urandom | md5sum | sed -r 's/^(.{6}).*$/\1/; s/([0-9a-f]{2})/\1:/g; s/:$//;'` ...to this: MACADDR="fe:16:3e:"`head /dev/urandom | md5sum | sed -r 's/^(.{6}).*$/\1/; s/([0-9a-f]{2})/\1:/g; s/:$//;'` ...and now the freezing is gone. Since this is my own custom script, I'm not sure what package it would belong to. Just be aware that this is a fundamental "bridge" issue and not limited to libvirt, KVM. It shows up with LXC and probably any other system where you add a new MAC. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/584048 Title: kvm images losing connectivity w/bridged network -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
