As discussed earlier, the implementation of the virtualization/SRIOV test was outdated, duplicating a lot of code, and did not include enough unit tests.
Pedro was worked on a cleaner implementation of the virtualization tests that is already merged in checkbox in the gpgpu provider: #1577

We will move this implementation to checkbox-support, but that PR is not yet in place. After discussing it with Max, we have decided that the best approach for the moment for the SRIOV tests is to move them away from virtualization.py tests.

We should copy the implementation of the LXD/LXDVM classes from that PR and add the SRIOV functionalities over this new implementation (copy-paste the LXD/LXDVM without modifying them and inherit from them for the SRIOV tests). That way we can reuse the tests already in place for the LXD/LXDVM classes

Once the LXD/LXDVM classes are in checkbox-support, we will create a new PR to import them from checkbox-support and remove the duplication.
