I've pushed out a new version of the test-appliance used by
kvm-xfstest and gce-xfstests. The kvm-xfstests appliances can be
found here:
https://kernel.org/pub/linux/kernel/people/tytso/kvm-xfstests
The gce-xfstests images can be found in the xfstests-cloud project in
Google Compute Engine with the image name
xfstests-{amd64,arm64}-202410151341. Most people who request their
gce-xfstests image from the xfstests-cloud project will get the latest
version automatically.
A new feature added since the last released appliance (a while ago),
the Lightweight Test Manager (ltm) will resume a VM after it crashes
or after it hangs, and will mark the test as being in state "error"
(as opposed "failed").
In addition, if $2 USD for 24 VM hours (2.5 hours of wall clock time
if run in parallel using ltm) when testing of all 12 of the ext4 file
system configurations with "gce-xfstests -c ext4/all -g auto" is too
rich for your blood, a new feature I've added to gce-xfstests is the
optional use of GCE preemptible instances. This will reduce the cost
by 60-91% (depending on your geography and VM type), with the tradeoff
that if the capacity of GCE zone you are using gets too busy by
customers willing to pay full price (for example, during Black Friday
and the Christmas shopping season more generally), the test VM will
get aborted. The ltm test manager will automatically attempt to
restart the test VM (after a capped expoential backoff) and the
xfstest will resume where it was preempted once low-cost cloud capcity
becomes available again.
The arm64 kvm-xfstests test appliance can also be used on MacOS, using
the qemu built from MacPorts. So for those people who want to run a
quick test on their Macbook Air while on an airplane flight, without
paying the double-virtualization penalty, this is now a possibility. :-)
BTW, I'm currently running:
gce-xfstests ltm -c ext4/all,xfs/all,btrfs/all,f2fs/all -g auto --repo https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next --watch fs-next
which runs daily test runs of the fs-next branch. I've also started
experimenting with:
gce-xfstests ltm -c ext4/all,xfs/all -g auto --repo stable-rc.git --watch linux-6.6.y
gce-xfstests ltm -c ext4/all,xfs/all -g auto --repo stable-rc.git --watch linux-6.1.y
etc.
My plan is to try to make the daily reports available via e-mail to
interested parties. Let me know if this would interest you.

appliance, please see:
