Unhelpful error when `libvirt` interface is disconnected

[sergiodj]

Describe the bug

I have multipass configured to integrate with libvirt, and I'm trying to simply launch an instance, but it's failing with:

launch failed: Cannot connect to libvirtd: Failed to open file '/etc/libvirt/libvirt.conf': Permission denied
Please ensure libvirt is installed and running.

To Reproduce
How, and what happened?

1. multipass launch -n test-focal focal

Expected behavior
The instance is launched successfully.

Logs
From dmesg:

Hi @sergiodj, you will need to snap connect multipass:libvirt now that Multipass is strictly confined (on edge). We'll improve the error message to suggest that, however.

Ah, it worked now! Thanks a lot :-). Will I have to perform this every time I reboot the machine?

Nice :)

No, it's a one-time thing, have a look at snap docs on interface management.
