[Bug 776936] Re: Running KVM guest causes kernel panic on host
In nat mode it does not panic. Having virtual machine in nat mode is piss poor, especially when the network performance in nat mode is very unreliable (perhaps issue with MTU? apt-get install gets stuck on 0% [Waiting for headers], wget google.com also hangs, while I can ping everything fine), another issue is I have to port forward and deal will all associated nightmare.

[Bug 776936] Re: Running KVM guest causes kernel panic on host
Today I noticed that although I removed the membaloon it didn't stick (possibly due to panic not syncing the file). I removed once again membaloon and started the guest with little bit better results. The system does not freeze immediately, but it leaves a lot of "oopses" in the syslog/dmesg. I am attaching these "oopses". The highlight of the "oopses" is "BUG: unable to handle kernel paging request at". I am going to try kvm in NAT mode (btw how do I do that?) and see if this is happening still. ** Attachment added: "messages" https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/776936/+attachment/2124149/+files/messages -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/776936 Title: Running KVM guest causes kernel panic on host -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
