Correction: SRU justification:
Impact: Guests hang during boot if they're using lvm and smp. Fix description: Mark pages as write protected *before* they're prefetched, so that the host can handle page faults in the guest. Patch: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=commit;h=a7c28c405ae69a9493b04d3b6209c0bd06472afb TEST CASE: Boot a hardy guest that uses root on lvm (create it with the guided lvm partitioning in the installer, if you don't already have one) like so: kvm -smp 8 -drive file=/path/to/your/disk.img,boot=on -m 256 Depending on your host hardware, this will hang anywhere between 10% and 99.9% of the time without the patch applied. With the patch applied, the problem should go away completely. -- 'BUG: soft lockup' after lvm or lvm+encrypt install when using 'kvm -drive' https://bugs.launchpad.net/bugs/221032 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
