Seems like sysbench is crashing with an Illegal instruction error while running the benchmark:

bash: line 21: 20650 Illegal instruction     (core dumped) bash -c "sysbench \\

There should be no differences between the version used in the Azure or GCE, but this seems to be failing only on the former. Given that we don't even collect any metrics in these runs (#123071), we could just skip this test on Azure.

I am guessing it's because of ROACHTEST_arch=arm64; i.e., the sysbench binary must have been built with amd64; double-checking...

Nope, it is picking up arm64 build of sysbench. I tried to reproduce this locally,

roachprod create --clouds azure -n1 --local-ssd=false --azure-machine-type Standard_D32pds_v5 stan-test --arch arm64
roachprod stage stan-test release v23.1.4 --arch arm64
roachprod start stan-test

sudo apt-get update;
sudo apt-get install -y sysbench

but it succeeded,

Evidently, sysbench is known to segfault occasionally [1], so there isn't much actionable here.
