I've been playing around with KVM virtual machines on my home server recently,
and have started using the `virt-sparsify` and `virt-resize` CLI tools
respectively to generate a compressed golden machine image and apply that image
to a new VM. After doing this and booting the new machine, I got this failure
after trying to load in a kernel module:
to a new VM. For example:
```
sudo virt-sparsify --compress --convert qcow2 /dev/vg0/debian-base debian-base.qcow2
sudo virt-resize --expand /dev/sda2 --no-sparse debian-base.qcow2 /dev/vg0/new-vm
```
After doing this and booting the new machine, I got this failure after trying
to load in a kernel module:
```
$ sudo modprobe bridge
modprobe: ERROR: could not insert 'bridge': Key was rejected by service
