I'm following this procedure: https://linuxhint.com/install-kvm-ubuntu-22-04/

When I apply the netplan for the yaml file I get an error:

sudo netplan apply
Failed to reload network settings: No such file or directory

Debug of netplan yields:

netplan --debug generate

Any idea what is causing the issue?

Just install qemu-system-x86, that will pick up kvm do what's necessary for networking. Your link starts with installing packages like qemu-kvm that don't even exist on Ubuntu 22.04.

Can you post your netplan config file? Seems like the parser is happy with the yaml but netplan not so much.

Also, KVM will start and run without the addition of the bridge and if you only want local VM's for a bit of testing you don't need it. The KVM install on ubuntu gives you a local NAT network out of the box with no effort required. So if you want to test the rest of the install you can revert the netplan file and give it a shot..

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
