Well, according to Steven it does, with viridian=0. Could you
re-check this?
While, according to AMD's processor specs page, the 3700X is just an
8-core chip, I wonder whether
https://lists.xenproject.org/archives/html/xen-devel/2019-09/msg01954.html
still affects this configuration as well. Could you give this a try in
at least the viridian=0 case? As to Linux, did you check that PVH
(or HVM, which you don't mention) guests actually start all their vCPU-s
successfully?
Jan
