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. -Adam Thompson athom...@athompso.net
