SRU justification: Impact: As soon as dom0 starts qemu it will try to locally attach QCOW(2) images in case a PV guest is using those. This results in the described errors and sometimes the whole host is rendered unusable.
Fix: Cherry picking an upstream patch (which was done already for Vivid) resolves the issues. Testcase: Prepare a PV guest that uses a QCOW2 image and try to start it. Depends on Xen starting dom0 (bug #1396068). -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu in Ubuntu. https://bugs.launchpad.net/bugs/1394327 Title: unmapping of persistent grants in qemu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1394327/+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
