One thing I thought of, is that both Brian and I have System76 computers, so perhaps there's a hardware issue specifically with our computers? Brian, I have a Darter Pro 2019, what model do you have?
Just to clarify I've tried both Pop_OS 19.10 and Ubuntu 19.10 and the issue is present on both installs. Perhaps it's an issue with the networking hardware on our systems in conjunction with the new 5.3 kernel? I have a Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 12) as my ethernet controller. I had some really strange issues with the ethernet with Ubuntu 19.04, in fact you can see some posts about this hardware here: https://ubuntu-mate.community/t/19-04-ethernet-wired-connection-refuses- to-connect-when-plugged-in-before-boot/19333/2 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1752772 My issue was that if I had the ethernet cable plugged in at boot, the connection wouldn't work. I would have to start the system, and plug the cable in afterwards. Even then it wouldn't always work correctly. My point is that perhaps there's something up very low level with this particular hardware? I wonder if we blacklist the ethernet kernel module we could run the VM without issue? -- 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
