VM guest details: 32-bit RHEL 5 compatible Qemu/KVM guest, really Scientific Linux 5.7. The guest was built from SL.57.090911.DVD.i386.disc1.iso plus today's updates. With 1 CPU it boots fine. With 2 CPUs it hangs. See attached screenshot of virt-manager plus virt-top. The disk and network activity in virt-top are always zeros when the VM is hung while the CPU activity is high. Note VM host has 6-cpu cores so 5.7% CPU is averaged across them. Regular /usr/bin/top shows /usr/bin/kvm getting 100% for this guest while it is hug. ** Attachment added: "screenshot of hung VM guest on 2.6.38-12 Natty host" https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/795717/+attachment/2581649/+files/OPSI-1720.png -- 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/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-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
