This seems like it should be very easy, so I must be missing something, but I cannot get my guest to communicate with my host or with the internet. I really jsut need some way to get files across, the guest doesn't even need internet access.
The host is RHEL 8.4, the guest is CentOS 8.
Everything is installed from the yum repos, so it's all default, but my corporate IT environment is pretty locked down. So that might be related.
I tried to use a shared drive, but apparently that is disabled in RHEL 8.
By default the network is 'NAT' with virtio.
Here's my guest ifconfig:

Here's the command line from the log file:
