My configuration might be a little off-topic, but I'm experiencing a similar problem so I thought I'd leave a comment here anyway.
I'm using qemu 0.13 on a Debian Squeeze host (kernel 2.6.32-5-amd64) running on a 64-bit Intel Xeon. The guest is a 64-bit Win 2008 R2. When I run the VM using qemu-system-x86_64 with -enable-kvm and no -smp options, the guest boots and installs fine. When I enable more than one core through -smp, the guest boots but completely freezes very soon. It seems to hang always, but not exactly at the same point. After the guest hangs, the qemu process keeps using 100% CPU. The same behavior happens on a different 64-bit Intel Xeon host running Debian Lenny with a custom 2.6.36 kernel. Also, the same behavior happens with qemu 0.14-rc1. I haven't tested yet if a Linux guest kernel hangs, but will do that. -- 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/714335 Title: KVM SMP Linux Guests Hang -- 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
