Today out of the blue...boom all sites down.

I use a bridge and virtual machines, 5 websites.

virsh shows me all machines are up and running, everything looks okay, but cannot get to sites.

Here are the errors listed in the log, condensed due to multiples of same errors.

there is some kid or error reading data, then there is some kind of network collision (bobnet, no idea what that is)

then it talks of cpus and out of room for data, but tons of room left...

any ideas i would be greatful

thanks
