View Full Version : [all variants] 8.04 KVM Restarting Networking in Host Breaks Networking In Guests

I have an Ubuntu 8.04 server running KVM hosting two JEOS 8.04 guests.

The networking is set up exactly as specified in the help pages using bridged networking and the virtio drivers as detailed here: https://help.ubuntu.com/community/KVM/Networking

The host and both of the guests are using static IP addresses.

It all works very well however I have noticed that if I restart networking on the host the guests loose the ability to connect to the network and restarting networking, or rebooting the guest doesn't help.

The only way I have found to get the networking working again on the guests is to use virsh to destroy the machines and then start them again.

Ideally I would like to do something less drastic to get it up and running again. Is there anything anyone can suggest?

It makes sense, it's a bridge connection, ie bonded to eth0 or whatever number you used. As for what's happening afterwards, I have not had this situation, so I can't shed any light on it.
