In https://autobuilder.yoctoproject.org/typhoon/#/builders/79/builds/3325/steps/15/logs/stdio there are multiple instances of: waiting at most 300 seconds for qemu pid (03/22/22 02:37:28) Qemu pid didn't appear in 300 seconds (03/22/22 02:42:29) Each of which corresponds to the systemtap test instance failing.
This was centos7-ty-4
Copy done in 296.2610318660736 seconds Copy done in 293.46104764938354 seconds So both were really slow at copying and then qemu didn't boot in 4s. Likely and IO load issue.
