Fyi - QEMU/KVM, internet connections stopped on all vms, SOLVED

FYI. I am using leap 15.5 as host for 6 various vms. Internet connection (by lan) stopped on all vms after 11/2 updates to leap. I have nvidia graphics on host and there was an nvidia update.

After flailing around for a couple of hours, a reboot of host machine restored all the internet connections for the vms.

Hope this helps someone, tom kosvic
