I'm running an Ubuntu 12.04 LTS VM host and using KVM for guest machines.
I'm having an issue with a KVM of mine that runs Zimbra and loses network connectivity (it's bridged) from the outside after a few hours. When I go back to the VM host and into the console for the guest, it works fine (almost like moving the mouse to get rid of a screensaver) but when I leave it untouched for a while, I suddenly lose the ability to connect to it.
I've tried both the virtio and e1000 drivers but I'm still running into this issue. Any suggestions?
