I've tried it on an Ubuntu 10.04 64bit host, with qemu-kvm 0.12.3 +noroms-0ubuntu9.2 , and a Lucid 64bit guest with kernel 2.6.32-26. Host is an AMD Phenom II X3 720, not exactly an Opteron but it's AMD.
What I observed is when starting the guest from a powered off position it boots much faster as opposed to doing a reboot after it started. After every reboot it kinda seems freezed for a good couple of seconds after the kernel loads (removing "quiet" helps to see the kernel messages). Seems like on every reboot it just gets slower and slower. After like 4-5 reboots, it takes 15-20 seconds to get over the kernel and go on with the boot process. This doesn't happen with a single CPU on the guest. Not sure if it helps or not, but seems a bit strange. Maybe you want to check this, does it really lock up, or it just takes a while to boot? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/669818 Title: Update to 10.04 2.6.32-25 as KVM Guest no longer boot -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
