Simplify our image handling by not copying both QCOW2 and raw images for
every test. Allow the test to choose QCOW2 or raw by specifying the
image name manually. A follow on patch will add explicity QCOW2 tests.

When an SSH command fails we want to be able to see, via a panic() why
and where it failed. Replace use of .unwrap_or_default() from SSH
command calls to ensure that we can see the location of the panic.
Also enhance the existing SSH output code to show the error if there is
one.

Based on the LKML feedback, the devices under /dev/sgx/* are
not justified. SGX RFC v40 moves the SGX device nodes to /dev/sgx_*
and this is reflected in kvm-sgx (next branch) too.
Update cloud-hypervisor code and documentation to follow this.

If the vCPU thread calls log!() the time difference between the call
time and the boot up time is reported. On most environments and
architectures this covered by a vDSO call rather than a syscall. However
on some platforms this turns into a syscall.

them takes a T and needs to use the specific width.

The boot time for direct kernel boot based tests is significantly
quicker than booting via the firmware and stock kernel as it triggers a
reboot during the boot process due to the initrd handling.
Signed-off-by: Rob Bradford <robert.bradford@intel.com>
When doing a direct kernel boot only have console=ttyS0 in the command
line if we are explicitly testing the serial output. The default
behaviour is `--serial null` so this output will not be visible but will
trigger a KVM exit for every byte which is very costly when running
under nested virtualization.
