Triaging old bug tickets... can you still reproduce this issue with the latest version of QEMU? Or could we close this ticket nowadays? ** Changed in: qemu Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1353947 Title: Hypervisor with QEMU-2.0/libvirtd 1.2.2 stack when launching VM with CirrOS or Ubuntu 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1353947/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Indeed, with qemu 1.5 we did not observed this issue at all.

Sorry, when the table only had the two entries i drew some bad assumptions from that, and I also missed the fact that hangs were in the host kernel. To be clear, running qemu 1.5 on the same host kernel has no issues with any guest, while qemu 2.0 causes host kernel to hang (indefinately) with some guests? Then indeed disregard my comment #5. Is this 100% reproducible, every time?

Hello Serge, I agree that there is probably some missing feature in the guest kernel. However, I don't believe it is acceptable for the hyper-visor kernel to be affected from this. Actually, this is a security issue if a VM user can crash i't Host kernel and probably some other VMs as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1353947 Title: Hypervisor with QEMU-2.0/libvirtd 1.2.2 stack when launching VM with CirrOS or Ubuntu 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1353947/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks, so the problem appears to be that a feature is missing from the guest's precise kernel, which was present in the saucy (13.10) kernel. Could you verify whether using the LTS backport kernel packages in the precies guest fixes the issue? ** Also affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1353947 Title: Hypervisor with QEMU-2.0/libvirtd 1.2.2 stack when launching VM with CirrOS or Ubuntu 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1353947/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
