Added use of a configuration to tests/vm/basevm.py.
The configuration provides parameters used to configure a VM.
This allows for providing alternate configurations to the VM being
created/launched. cpu, machine, memory, and NUMA configuration are all
examples of configuration which we might want to vary on the VM being created
or launched.
This will for example allow for creating an aarch64 vm.

Changes to tests/vm/basevm.py to allow accepting a configuration file
as a parameter. Allows for specifying VM options such as
cpu, machine, memory, and arbitrary qemu arguments for specifying options
such as NUMA configuration.
Also added an example conf_example_aarch64.yml and conf_example_x86.yml.

Added ability to view console during boot via
--boot-console switch to basevm.py. This helps debug issues that occur
during the boot sequence.
Also added a new special variable to vm-build:
BOOT_CONSOLE=1 will cause this new --boot-console switch to be set.

Hmm why isn't this output covered by DEBUG=1? I'm wary of adding another
debug knob rather than just including the extra information under our
existing DEBUG output.

This is a good point. I will add this support under DEBUG=1.

Added a new special variable QEMU_LOCAL=1, which
will indicate to take the QEMU binary from the current
build.

ubuntu.aarch64 provides a script to create an Ubuntu 18.04 VM.
Another new file is also added aarch64vm.py, which is a module with
common methods used by aarch64 VMs, such as how to create the
flash images.

This change converts existing scripts to using for example self.ROOT_PASS,
to self._config['root_pass'].
We made similar changes for GUEST_USER, and GUEST_PASS.
This allows us also to remove the change in basevm.py,
which adds __getattr__ for backwards compatibility.

The ConsoleSocket object provides a socket interface
which will consume all arriving characters on the
socket, but will provide those chars via recv() as
would a regular socket.
This is a workaround we found was needed since
there is a known issue where QEMU will hang waiting
for console characters to be consumed.
We also add the option of logging the console to a file.

Hi Robert,
Sorry I didn't get to this in the run up to 4.0. I've tried applying the
series to the current master but I ran into conflicts pretty early on. I
think the first patch conflicts with f01454ad17 because I had already
cherry picked some of the cleanups to gen_cloud_init_iso and then had to
fix it up. Skipping it caused the next patch to fail to apply so I
decided to back away from misapplying the series.
Would you be able to re-spin on current master please?

Sure, I will respin. There is a v5 out for this series from 4/30 with
some additional minor fixes, but I will update the series from the
current master with the change around removing BOOT_CONSOLE and
putting it under DEBUG=1.
Thanks & Regards,
