Hi Brian and Robert, interesting yet disturbing crash that is - thank you for the report.
The apparmor message you see (at least those in the log provided) are just from being unable to access an extra disk in "/home/brian/.seconddrive/windows10/WindowsVM.img". Which on itself is odd as we ahve this rule for virt-aa-helper (that isn't the guest but a helper that runs in advance). # for backingstore -- allow access to non-hidden files in @{HOME} as well @{HOME}/** r, But at least for now I'd not focus on apparmor since as I said that is disk and not network related. And I never saw qemu being denied to access it, just the helper tool. ** Changed in: qemu (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1849720 Title: Running VM with Virtual NIC Crashes Host OS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1849720/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
