@robstrube, would you mind stepping back a little bit and making a summary of attempt changes and effects, and attaching the following information:
- host kernel exact version - guest kernel exact version - qemu packages exact version - windows kernel exact version - virtual machine xml (virsh dumpxml <machine>) if the problem is within kernels 5.0.0 and 5.3.0 this is easily investigated through a kernel bisection, even if it is a qemu code change causing this issue with the kernel, because we can see the nature of the kernel change that caused it. i'm trying to organize a bit the approach so we can help you, would you mind providing the items I asked ? hopefully, with those answers, I'll be able to reproduce this on my side as well, using the exact VM definition you have, and then I can bisect the kernel very easily and take needed actions. thank you -- 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
