Hmm, no I have not noticed that sort of issue, but we do see random hangs with our nested VM’s running UC20 on Google Compute Engine as part of our spread test which we have never been able to identify the cause of, our leading guess is hypervisor bugs in the L1 VM in GCE (in this case UC20 is a L2 VM). These VM’s do use encryption with swtpm, etc. as well
