This is happening in juju 3.1.2 deploying KVMs on top of an LXD clusters.

# Steps to reproduce:

1. Add machine

juju add-machine --constraints="virt-type=virtual-machine mem=4G cores=4 root-disk=40G root-disk-source=remote" --base ubuntu@22.04

2. When machine is ready deploy Microk8s on it with:

juju add-unit microk8s --to <id-of-the-machine>

# Expected result:

Unit starts installing on the machine

# Actual result:

Machine goes to error state with message:

19 error 172.16.0.16 juju-657122-19 ubuntu@22.04 cannot upgrade machine's lxd profile: update failed: Key "linux.kernel_modules" cannot be updated when VM is running

# Workaround:

Stop the VM and then start with:

lxc stop --force juju-657122-19
lxc start juju-657122-19

and machine will no longer be in error state and once the KVM is running again unit will start installing on it.
