I'm closing this issue with my VPS provider, so wanted to follow up here as well. My VPS provider changed the network interface from virtio_net to e1000. Once we made that change, the VPS stopped crashing, but querying local bind9 for www.debian.org. for example, and running openswan as responder now produces a kernel panic. The VPS itself stays up, but I'm forced to do a hard shutdown, and boot it up again. So, I opened a bug against what was at that time the latest debian kernel: <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=719668> It may still be the latest kernel for all I know, but I went back to the stock 3.2.0 kernel that comes with squeeze. The one good news is that before kernels 3.4.56 and older caused the VPS to crash at times during boot if bind9 was started while the eth0 interface was up. This doesn't happen anymore under the stock wheezy 3.2.0 at least, since the switch to e1000. I can stop/start bind9 as much as I want now while eth0 is up without a system crash, or kernel panic. Yes, I could be migrated to a host with a newer KVM/QEMU version. This however isn't automated, and would incur a labor charge as a result. Since I've found workarounds (below), and since the migration doesn't guarantee a resolution to this, I decided to leave things as they are. I decided to not use my local bind9 for queries in /etc/resolv.conf for now. I may try pdns-server one day to see how it does as far as the crash/kernel panic. I also got openvpn going with my laptop able to have a publicly routed IP address through my VPS. I would like to thank Zenaan here for nudging me in the right direction to get this going. I also want to apologize to Zenaan and the list if it seemed like I was nitpicking during our exchange. That was not my intent. I just wanted to make sure I understood what Zenaan was getting at. I also want to thank Bob for his response to my initial post in this thread. If there is further news on this issue, it will likely take place in the kernel bug ticket I gave above. If I do manage to find a solution where openswan/bind are fully operational in my VPS on the same host, I will post it here if it doesn't end up in the debian bug tracker.
