Libguestfs - Jan 2022 - [PATCH v2v 5/7] tests: Drop ancient Ubuntu versions, add Ubuntu 20.04 LTS

$ make && make check-slow

I hadn't run this set of tests in a while and they were all failing.
Luckily that was easy to fix (see patches 1 and 2).

However we need to change the mix of guests being tested, dropping
some old ones which are no longer testable, and adding some newer
ones.

There is one slow test which still fails (test-v2v-trim.sh) which I'm
still looking at.

Rich.

According to https://libvirt.org/formatdomain.html only vnc and sdl
graphics types support port/autoport.

In addition, autoport='yes' is the non-deprecated replacement for
port='-1'.  Since we don't need to support ancient libvirt, we
don't
need to keep adding port='-1' in the autoport case.  virt-xml-validate
rejects our XML if it has both attributes.

According to https://libvirt.org/formatdomain.html#vsock it's <vsock/>
not <viosock/>.  There is also no model="none", we just omit it
if not
present.

According to https://wiki.qemu.org/Features/VirtioVsock the qemu
parameter is -device vhost-vsock-pci.

For very old Fedora versions, it's no longer possible to download the
packages (required by virt-builder --update).  We get this error:

Error: Cannot retrieve metalink for repository: fedora/20/x86_64. Please verify
its path and try again

I also dropped Fedora 23 and 29.  Although those can be updated, it's
not really worth testing long-obsolete versions of Fedora.  More
useful is testing the long-term stable equivalents (ie. CentOS and
RHEL).

I did however add the current version of Fedora (35) because it's
worth testing that current Fedora conversions work.

The image cannot be updated, see error below.  In any case we are
testing a RHEL 6 image so it is not really necessary to continue to
test CentOS 6.

The error was:

virt-builder: error: cannot use ?--update? because no package manager
has been detected for this guest OS.

If this guest OS is a common one with ordinary package management then this
may have been caused by a failure of libguestfs inspection.

For OSes such as Windows that lack package management, this is not
possible.  Try using one of the ?--firstboot*? flags instead (described
in the manual).
