Comment 22 for bug 2032176

It seems the build failed for https://launchpad.net/~smb/+archive/ubuntu/jammy. I tried the PPA but it seem I was unable to install `linux-generic` due to:
```
Package linux-image-5.15.0-83-generic is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
```

I have 5 instances of the charm with the VM set to tdp_mmu=false. I have check the output is "N" for "cat /sys/module/kvm/parameters/tdp_mmu" on all the VM. Because I do not have direct access to the openstack instance, I can only create the juju application, get the instance allocated, then set the tdp_mmu config and reboot.
