Hey all,
Thanks a lot for your comments, they helped me to realize that I was configuring/doing something wrong.virtualization type in the hypervisor.
Thanks again

Yeah, it looks like the signature is just wrong. Even setting aside the question of padding, I used rsautl -verify -raw on the signature using the CSR's public key, and I would expect to see a pair of sequence tags (0x30) with sensible lengths somewhere inside, and I don't.

Where you can clearly see the two sequence tags after the end of the padding.

As to how this *happened*, I'm afraid I've no idea.

It’s been a while since I did this, but I *believe* you could check this by extracting the bytes for the first-nested SEQUENCE from the ASN.1 structure, get the signature for that blob against your private key, then compare that to the CSR’s stored signature. They should be the same.
