New Windows Server 2019 install fully updated and virtualized using libvirt on CentOS 7. Any time the network settings are clicked in the taskbar the entire system crashes with no trace in the system logs. There are no reports of this anywhere on Google.

Final resolution was to change the adapter type from e1000 to virtio in the VM settings and then install the virtio driver for the Ethernet Controller in the OS. After that there have been no issues… I mean no issues other than all the other issues Windows Server commonly has.
