Could you show the contents of /etc/xen/scripts/vif-bridge? Is it random whether the 10.x.x.x or 216.x.x.x device goes down? Is it perhaps always the one with the higher or lower mac address? Once this affects a guest, and after a reboot, does it ever re-occur on the same guest? You showed

vif-bridge: https://gist.github.com/26ce1eea5a1db0ae26a6#file_vif_bridge.sh It seems to be random, no pattern as far as we can tell. We've had guests lose one, then the other after a reboot. I haven't noticed if it has anything to do with Mac addresses. I'll check next time. Yes, we have seen

Thanks @Alexander. When vnet0 is the working device, then can vnet1 talk to the host at least, or not even that? It looks like you're using a custom kernel. Is there any chance of trying with a stock kernel? Actually I'm pretty sure your issue would be different from Jesse's. Could you please

I actually custom-compiled the kernel in an attempt to mitigate the issue. I used 2.6.35-27-generic when the problem first appeared. Both virtual instances (tapped by vnet0 and vnet1) can always reach each other, as well as the host. As per your request, I will file a separate bug report. --

2.6.32-0206322611-generic was being used on this server. Unfortunately, we just had another virtual server that *is* running 2.6.35-23-virtual and does not have the xen_* modules lose network connectivity on one interface. -- You received this bug notification because you are a member of Ubuntu

So if I understand correctly, this does not in fact appear to be a bug in the kernel? Sorry if I've asked this before, but is there definately nothing in the guest's syslog right before the connection is dropped? I'm afraid I don't know enough about xen setups to be able to guess at what might

I'm not sure where the bug lies at this point, to be honest. There nothing in syslog before and after. There is nothing different on the host between upgraded and installed guests at all, and it appears this problem is occurring on KVM as well. Xen is not the issue. The problem not yet

We just had a guest lose networking. 'rmmod xen_netfront' caused the other interface to go down, and I surmise removing the other module would fail because of the attached devices: # lsmod | grep xen xen_netfront 14919 0 xen_blkfront8991 2 Turns out this

Thanks for filing this bug. Have you tried doing 'rmmod xen_netfront xen_blkfront' on an upgraded host? I'm not familiar enough with Xen to know which interfaces do what, but several of the interfaces on the host do have the same hwaddr. Do you know whether that can be related? In particular,
