      tests/qtest/hd-geo-test: fix incorrect pcie-root-port usage and simplify test · 579edbd4
      Ani Sinha authored 
      
The test attaches a SCSI controller to a non-zero slot and a pcie-to-pci bridge
on slot 0 on the same pcie-root-port. Since a downstream device can be attached
to a pcie-root-port only on slot 0, the above test configuration is not allowed.
Additionally using pcie.0 as id for pcie-to-pci bridge is incorrect as that id
is reserved only for the root bus.

In the test scenario, there is no need to attach a pcie-root-port to the
root complex. A SCSI controller can be attached to a pcie-to-pci bridge
which can then be directly attached to the root bus (pcie.0).

Fix the test and simplify it.

      Ani Sinha authored 
      
Some fixes were committed in bios-tables-test in the previous commit. Update
the acpi blob and clear bios-tables-test-allowed-diff.h so that the test
continues to pass with the changes in the bios-tables-test.

Following is the asl diff between the old and the newly updated blob:

We don't have a virtio-scmi implementation in QEMU and only support a
vhost-user backend.  This is very similar to virtio-gpio and we add the same
set of tests, just passing some vhost-user messages over the control socket.

      tests/qtest: massively speed up migration-test · e02f56e3
      Daniel P. Berrangé authored 
      
The migration test cases that actually exercise live migration want to
ensure there is a minimum of two iterations of pre-copy, in order to
exercise the dirty tracking code.

Historically we've queried the migration status, looking for the
'dirty-sync-count' value to increment to track iterations. This was
not entirely reliable because often all the data would get transferred
quickly enough that the migration would finish before we wanted it
to. So we massively dropped the bandwidth and max downtime to
guarantee non-convergance. This had the unfortunate side effect
that every migration took at least 30 seconds to run (100 MB of
dirty pages / 3 MB/sec).

This optimization takes a different approach to ensuring that a
mimimum of two iterations. Rather than waiting for dirty-sync-count
to increment, directly look for an indication that the source VM
has dirtied RAM that has already been transferred.

On the source VM a magic marker is written just after the 3 MB
offset. The destination VM is now montiored to detect when the
magic marker is transferred. This gives a guarantee that the
first 3 MB of memory have been transferred. Now the source VM
memory is monitored at exactly the 3MB offset until we observe
a flip in its value. This gives us a guaranteed that the guest
workload has dirtied a byte that has already been transferred.

Since we're looking at a place that is only 3 MB from the start
of memory, with the 3 MB/sec bandwidth, this test should complete
in 1 second, instead of 30 seconds.

Once we've proved there is some dirty memory, migration can be
set back to full speed for the remainder of the 1st iteration,
and the entire of the second iteration at which point migration
should be complete.

On a test machine this further reduces the migration test time
from 8 minutes to 1 minute 40.

      tests/qtest/readconfig: Test the docs/config/q35-*.cfg files · bc55e2ea
      Thomas Huth authored 
      
Test that we can successfully parse the docs/config/q35-emulated.cfg,
docs/config/q35-virtio-graphical.cfg and docs/config/q35-virtio-serial.cfg
config files (the "...-serial.cfg" file is a subset of the graphical
config file, so we skip that in quick mode).

These config files use two hard-coded image names which we have to
replace with unique temporary files to avoid race conditions in case
the tests are run in parallel. So after creating the temporary image
files, we also have to create a copy of the config file where we
replaced the hard-coded image names.

If KVM is not available, we also have to disable the "accel" lines.
Once everything is in place, we can start QEMU with the modified
config file and check that everything is available in QEMU.
