Hello Todd, This issue (Virtual hardware issue happens on latest proxmox5.x but not on Proxmox 4.4 ) with 6.2 (and 6.1 for that matter) It is discussed here https://marc.info/?l=openbsd-misc&m=151472854021947&w=2
but in recent versions of Proxmox 5.1 (QEMU/KVM) there were no console freezes (Proxmox updates fixed this issue (ie virtual Hardware Fix not an OpenBSD Software Fix) https://marc.info/?l=openbsd-misc&m=151467636114177&w=2 So OpenBSD 6.2 Runs Fine on older QEMU and KVM but not on latest KVM QEMU My 2 cents is that the issue is a change in Virtual Hardware that is incompatible with OpenBSD as opposed to change in OpenBSD that has caused the issue, in my humble opinion it is more likely a old driver incompatibility with newer (Virtual) hardware. I hope this helps Tom Smyth
