Probably not purely a KVM problem; I'm running OpenBSD 5.3-RELEASE inside KVM
(ProxmoxVE 3.1 platform) on Intel CPUs, and ACPI handling works correctly. I
also recall testing OpenBSD 5.2-RELEASE inside RedHat Enterprise Virtualization
(also KVM-based) and it worked fine there on AMD chips.
The only HVM-related issues I've been able to find are a) speed [no surprise
there], and b) the long-standing red-console-background effect when switching
VTs.
This implies that you're seeing a bizarre interaction between your guest, your
host, and the VM software. It's remotely possible your hardware has something
to do with it, but unlikely. I haven't tested anything illumos-based.
