Ok you both had e1000e as I had in my test. The guest xml has no very special config that would make me wonder.
You said there is no crash report, and the guest log confirms that it seems to end kind of normally. 2019-10-23T03:01:14.664402Z qemu-system-x86_64: terminating on signal 15 from pid 1899 (/usr/sbin/libvirtd) That means libvirt told him to end which is fine. Robert said there also where no kernel panics or anything. Could you outline these two things please: - you said "crashes on the host" but we lack crash reports, how would such a crash look like exactly? - maybe one can get a journal log while the crash is happening, as it might be libvirt who thinks it needs to shut down the guest (at least from what we see so far)? -- 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
