=====Notes=====


====OpenBSD/i386 slow====

Disable mpbios and acpimadt.

<code>
rebooted (which took also a while), at the boot> prompt did boot -c to enter the kernel config, then at the UKC> prompt did:
disable mpbios
disable acpimadt
quit

boot speed was then... normal, the VM performed normally, and the kvm process didnt consume cpu resources from the host.

logged in as root, edited /etc/bsd.re-config to contain
disable mpbios
disable acpimadt
so that it was applied on upgrades on the newer kernel linked at the end of the upgrade process.
