I too get this after an upgrade and I can add only a couple of things to Viktor's report. I've tried both aio=native and aio=threads with same result. Unlike Viktor, I'm using virtio-blk-pci with raw images.
With both aio=native and aio=threads: qemu-system-x86_64: /build/qemu-v_zvmu/qemu-2.11+dfsg/util/aio-posix.c:592: aio_poll: Assertion `in_aio_context_home_thread(ctx)' failed. $ apt-cache policy qemu-kvm qemu-kvm: Installed: 1:2.11+dfsg-1ubuntu7.27 Candidate: 1:2.11+dfsg-1ubuntu7.27 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1885419 Title: QEMU crash using virtio-scsi with iothread To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1885419/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
