Good news! kernel from proposed repositories works. It didn't crash overnight in bridge mode. -- 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
[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
[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. I am seriously considering moving to physical box, or ditch ubuntu, install debian and go with xen... I need this box in bridge mode (it is a virtual server after all). -- 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

One thing I noticed that kernel panic comes much faster if there is network activity on the guest. Although I might be wrong... Anything else I could do?
