Well some of the update packages are a mess anyway.<\/p>\n
Did a simple ‘yum update’ on the VM host machine. Something in one of the rpm pre\/post update scripts decided to destroy the network configuration completely. The host server plus all the VMs on that machine just went off the network.<\/p>\n
The hard drive light on the host server was still blinking, so plugged a screen into it. An ‘ifconfig’ command showed the entite network setup had been blown away as part of the update; only physical interfaces showed and with no assigned ip-addresses; the bridge configuration was also gone.<\/p>\n
Bother. Had to ‘virsh destroy’ all the VMs (as without a network I couldn’t login to them to shut them down cleanly) and reboot.<\/p>\n
On the reboot it reran the network scripts correctly and bridging is back and the host and guests accessable again. <\/p>\n
I probably should go CentOS, but I have started using a lot of the new features in Fedora that probably won’t be rolled into RedHat for a few years yet, so I’m sort of stuck with Fedora.<\/p>\n
