[EXTERNAL] [edk2-devel] Information about the VMs used to do EDK2 CI?

[Rebecca Cran]

Thanks! It was the singe-threaded part that I was interested in. But
also, it sounds like for more complex/in-depth testing such as running
QEMU to do runtime validation and regression-testing of OVMF etc. we'll
want to set up our own agents, since the hosted ones are relatively
restrictive.
