----------------------- snip centos 6 host, centos 6 virtual machine. Network connection from outside server disappears in regards to the virtual server. snip ----------------------- Tested the heck out of it. Further testing shows the network unreachable, even if network restarted in host. A simple ping from the virtual machine going out allows full traffic both ways. Intermittent time out, it may last 5 minutes, it may last an hour, but it will disappear. I found a small config sample on an old website in the middle of nowhere. It had an addition to the /etc/sysconfig/network file of the host. it added "GATEWAY=br0" I did this and restarted the network service and I believe without me doing anything, this appeared in the virtual machine message logs, something that had never appeared before. kernel: Bridge firewalling registered so hoping that is it...not sure if I would need to do that on the virtual machine or not. I have been days at this. Literally rewrote every single ifcfg and conf file I could find. Tried hundreds of permutations. Nothing has worked. If this does not work I am willing to pay someone to end my week long battle with the virtual machine network being unreachable no matter what I do. But only if you actually know this stuff and actually have experience with the virtual machine bridging..and hopefully have seen this type of issue... <banging head on wall> <repeat> <rinse> <repeat>
