Public bug reported: The vhost code currently assumes vring are mapped in memory following the legacy virtio layout. This may cause QEMU to fail with virtio 1 devices if the used ring is mapped below the descriptor table.
This got fixed upstream already and will be available in QEMU 2.8. http://git.qemu.org/?p=qemu.git;a=commit;h=f1f9e6c5961ffb36fd4a81cd7edcded7bfad2ab2 http://git.qemu.org/?p=qemu.git;a=commit;h=1cdce7c54d26e64f5eddb10a6f4f7dd938dfc2c4 ** Affects: qemu (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/1642912 Title: vhost vring layout incompatible with virtio 1.0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1642912/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
