I have ran a win10 install on 19.10 in virt-manager with the e1000e card that you used as well ... nothing is crashing :-/
And the network surely is used ... $ virsh domifstat win10 vnet0 vnet0 rx_bytes 9306542 vnet0 rx_packets 51933 vnet0 rx_errs 0 vnet0 rx_drop 0 vnet0 tx_bytes 1591661 vnet0 tx_packets 5049 vnet0 tx_errs 0 vnet0 tx_drop 0 I can't reproduce the bug as-is, we need to find what is different for you. You said it crashes later "when it accesses network" at what stage is that? Might my install test not be far enough? reading the logs you attached now ... -- 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
