We check the guest boots and we are able to install a package. Different guest configs are tested: standard, passthrough an strict=0. This is tested with both fedora 31 and 33. The former uses a 5.3 kernel without range invalidation whereas the latter uses a 5.8 kernel that features range invalidation.
