I could not reproduce booting the guest by setting processor affinity to a single host CPU.
1. Start 32-bit 2-CPU RHEL-5 compatible VM guest and pause on grub screen 2. locked it to host CPU #1 $ sudo taskset -p 0x00000001 3127 pid 3127's current affinity mask: 3f pid 3127's new affinity mask: 1 3. Let the guest proceed booting from grub and it hung at a different time, right after displaying: Time: kvm-clock clocksource has been installed. gdahlman probably mean single guest CPU not single host CPU. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/795717 Title: 32bit rhel and centos 5.(5|6) hangs on boot on natty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/795717/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
