This gets rid of the loop that was polling for things to do every 0.25
seconds and instead, reacts to any data from VMs as soon as it becomes
available. This avoids unnecessary operations when no new data is
available and avoids unnecessary waits when new data becomes available
more quickly.

This is more efficient since we can now start only the necessary number
of VMs instead of always forcing all VMs to start with one second delay.
This can also control the starting delay by keeping at most two VMs
starting at a time instead of using the hardcoded one second wait for
each consecutive VM.

Now that parallel-vm.py is actually stopping VMs as soon as they are not
needed for retries, it is not really an unexpected exit to see a VM exit
while test cases remain in the queue as long as at least that many VMs
remain running. Get rid of confusing 'unexpected exit' status from the
UI in such cases.

This removes the separate rerun step from the parallel-vm.py processing
and instead, simply requeues the failed test cases into the same queue
that is used for the initial run. This is simpler and more efficient
since reruns start as soon as any VM is ready for processing them
instead of having to wait for all VMs to complete the first round.
Furthermore, this allows VMs to be stopped sooner when no more test
cases remain and that is helpful especially with the time travel patches
that make the wait-for-next-test step in the VM use all available CPU.

Print a list of full paths to log files from failed test cases both the
parallel.log and stdout so that they can be easily opened for analysis.
In addition, renumber the VM lines in the <timestamp>-parallel.log to
match the i+1 numbering used in the log directories and UI that is
tracking test execution.

The result of reading non blocked empty stream is different between
python2 and 3. The python2 sends "[Errno 11] Resource temporarily
unavailable" exception. The python3 could read "None" without
exception, so handle this "None" case as well.

If telnetd is installed and --telnet <port> is passed on the
vm-run.sh command line, start a telnet server (directly connected
to bash, no login) inside the VM(s) to be able to look into them
when something is wrong. Use a user network in qemu with a single
host forward from the specified port for this, listening only on
'localhost'.
Please note that this provides unauthenticated access to the guest
system from anything that can open a TCP connection on the host system.
The guess system does have access to reading all files on the host that
the user account running kvm has access to (and even write access if the
default ROTAG ,readonly parameter is cleared). In other words, this
option should not be used on any multiuser systems where kvm is run
under user accounts that are not dedicated for testing purposes (i.e.,
do not have access to any files that should not be readable to
everyone).
This needs CONFIG_VIRTIO_NET=y in the guest kernel.
For parallel-vm.py, the --telnet argument specifies the base port
and each VM index (0, 1, ...) is added to it.

This is useful for now since the IPv6 support for proxyarp is not yet
included in the upstream kernel. This allows the IPv4 test cases to pass
with the current upstream kernel while allowing the IPv6 test cases to
report SKIP instead of FAIL.

Now that vm-run.sh supports a long list of test cases without crashing
the VM kernel, there is no need to use the "parallel-vm.py -1 1 <tests>"
workaround. Print the re-run example commands with vm-run.sh instead. In
addition, add the --long argument if it was specified for the test run
to avoid skipping test cases in the re-run case.

If /tmp has a relatively small size limit, or multiple people run the
tests on the same machine, using the same output directory can easily
cause problems.
Make the test framework honor the new HWSIM_TEST_LOG_DIR environment
variable to make it easier to avoid those problems.

This can be used to filter out test cases that take significantly longer
time to execute (15 seconds or longer). While this reduces testing

It's somewhat annoying that you can only run parallel-vm.py as

Merge partial lines together before processing them in parallel-vm.py.
This avoids issues in cases where the stdout read gets split into pieces
that do not include the full READY/PASS/FAIL/SKIP information. In

parallel-vm.py is now retrying failed cases once at the end of the run.
If all the failed test cases passed on the second attempt, that is noted
in the summary output. Results are also indicated as the exit value from

but everything passed after one retry, 2 = some cases failed did not
succeed at all.

This allows all VMs to be used at the end of a test sequence by
assigning test cases to VMs based on which VM is available for a new
test case rather than splitting the full task at the beginning and
potentially getting stuck with the last VM running long test cases for
significantly longer than another VM that gets shorter duration tests
assigned to it.
