Thanks for testing that. Would you mind also testing the newest up-to-date backported kernel (see https://launchpad.net/~kernel-ppa/+archive/ppa)?

I'm talking about guest kernel. With the backport the add is done without crashing network.

If you don't make the modprobe acpiphp, device hot-plug is not working, so this bug prevent hotplugging drives and network interfaces on lucid.

[Bug 602060] Re: Virtio network stops working after dynamic virtio disk attachment
Sorry, what is the 'bug'? If it works after a 'modprobe acpiphp', then I think this bug needs to be marked invalid against libvirt and eucalyptus. You can make the module be automatically loaded by listing it in /etc/modules.conf If you want to pursue a bug against the kernel to have acpiphp built in, or to have acpiphp put into /etc/modules, then you can do that by using the 'also affects' at the top of this bug listing in launchpad. So, does it work for you after modprobe acpiphp? ** Changed in: libvirt (Ubuntu) Assignee: Serge Hallyn (serge-hallyn) = (unassigned) ** Changed in: eucalyptus (Ubuntu) Assignee: Serge Hallyn (serge-hallyn) = (unassigned) ** Changed in: eucalyptus (Ubuntu) Status: Confirmed = Invalid ** Changed in: libvirt (Ubuntu) Status: Confirmed = Invalid -- Virtio network stops working after dynamic virtio disk attachment https://bugs.launchpad.net/bugs/602060 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to eucalyptus in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Sorry i was not clear. The modprobe acpiphp is mandatory for device hot- plugging, but when you try to hotplug some device you loose network. Seem to be an acpiphp bug preventing device hot-plugging.

Ah, thanks. Seems I jumped the gun then. It still may be that the bug is actually in the guest kernel, but that's not certain. ** Changed in: eucalyptus (Ubuntu) Status: Invalid = Confirmed ** Changed in: libvirt (Ubuntu) Status: Invalid = Confirmed -- Virtio network stops working after dynamic virtio disk attachment https://bugs.launchpad.net/bugs/602060 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to eucalyptus in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 602060] Re: Virtio network stops working after dynamic virtio disk attachment
Thanks for reporting this and helping to make Ubuntu better. I've confirmed this on lucid. Started with a VM built in virt-manager, with ide root hd and virtio network card. Network works. Then I do 'modprobe acpiphp' in the guest, and on the host I do: virsh attach-disk 13 --type disk /home/serge/newdisk.img --mode shareable --driver file vda where 13 is the domain id and newdisk.img is obviously the disk. After this, network is not working. (Can't reach the host from guest, and re-running dhclient does not succeed, though ifconfig thinks eth0 is up) ** Changed in: libvirt (Ubuntu) Status: New = Confirmed ** Changed in: eucalyptus (Ubuntu) Status: New = Confirmed ** Changed in: libvirt (Ubuntu) Assignee: (unassigned) = Serge Hallyn (serge-hallyn) -- Virtio network stops working after dynamic virtio disk attachment https://bugs.launchpad.net/bugs/602060 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 602060] Re: Virtio network stops working after dynamic virtio disk attachment
Note that if I do not do modprobe acpiphp in the guest, then networking stays up.
