I changed the bug task to Qemu (Ubuntu) as this isn't a libvirt error. I also added an upstream qemu task in case this is a known issue for the developers there. Someone might be able to point us at a known discussion/fix.
The Backtrace I added in the last comment should help to identify known cases. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1867519 Title: qemu 4.2 segfaults on VF detach To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1867519/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
