Hi Sivaram,I'm the author of the e-mail thread that you mentioned. After feedback I got from OpenBSD community, I created a patch for Linux to enable kvm-clock when booting on VMM. It managed to keep clock in sync, but I experienced random crashes in vmd after some time running the VM.
Multiple fixes have been merged to vmm/vmd since then, so I'm planning to give it another try with OpenBSD 6.7.
If you are interested, I can share the patch with you. Regards, -- Renato Aguiar
