Migration of the aarch64 Fedora and RHEL buildbot to newer hardware
Hello everyone,
After a small downtime, the Fedora and RHEL aarch64 buildbots have been fully migrated from an Ampere eMAG 8180 hypervisor to an Ampere Altra 2U Mt. Jade, thanks to ARM and Equinix Metal.
Since the new hypervisor comes with 160 cores, each VM will now boast 40 cores and more RAM, speeding up the test suite run (pending for https://github.com/python/buildmaster-config/pull/256 ).
You'll notice 3 buildbots this time there instead of 4, as the RHEL7.6 one has been decommissioned and we are waiting for CentOS 9 Stream release.
So far it seems there are no issues with connecting to the buildbot main server, but do let me know if you notice anything.

Wow, that's great!
I looked at the latest green build (467) on aarch64 Fedora Rawhide 3.x. The maximum system load is around 24.1, regrtest spawns 40 child processes, the tests take 4 min 20 sec.
"0:00:00 load avg: 3.48 Run tests in parallel using 40 child processes (timeout: 15 min, worker timeout: 20 min)"
"0:01:07 load avg: 24.10 [409/427] test_regrtest passed (53.1 sec) -- running: test_asyncio (52.4 sec), test_gdb (54.4 sec), test_multiprocessing_fork (58.7 sec), test_tokenize (1 min 7 sec), test_multiprocessing_forkserver (53.7 sec), test_capi (1 min 1 sec), test_zipfile (1 min 7 sec), test_io (40.8 sec), test_multiprocessing_spawn (36.7 sec), test_unparse (37.5 sec), test_concurrent_futures (1 min 7 sec), test_lib2to3 (59.5 sec), test_subprocess (56.1 sec), test_selectors (42.8 sec), test_peg_generator (34.7 sec)"
"Total duration: 4 min 20 sec".
Nice ;-)

Yeah, it is a priviledge! :-)
Thank you, Charalampos and RedHat team.
