[rhos-list] EXTERNAL: Re: Red Hat Linux VM freezes.

[Minton, Rich]

Rolling back the kernel and libvirt broke everything and I had reinstall the latest versions.

It looks like it might be a routing problem. Our quantum router gateway IP is the same as our physical router IP and we think they are fighting over each other. I'll get my network engineer to look at it on Monday.

I'll let you know the outcome.

Rick

Interesting. I'm not sure about rolling back the kernel though. Is that not the version with the network namespace patches? FWIW, you can rollback with yum. Take a look at "yum history" and related functions (if the man page doesn't cover it, there are some good googl'able examples).

You asked earlier about which log files might be relevant. Let's start with:
- the contents of /var/log/quantum and /var/log/openvswitch
- the output of dmesg
- the output of ifconfig (don't specify an interface, let's get them all)

Cheers,
