OpenBSD 5.0	64	qemu-kvm-0.15.0, Linux 2.6.37.6 (Slackware 13.37)	Intel Core2Duo E8400	64	Works	SMP works, no need to disable mpbios anymore. Must use if=ide as the scsi interface will result in sd0(siop0) errors during install; recommend using the e1000 network driver as well. More information can be found here.
OpenBSD 4.9	64	qemu-kvm-0.14, linux 2.6.38.4 (Fedora 15 Beta)	AMD Phenom(tm) 9650 Quad-Core	64	Works	Disable mpbios as with 4.5

OpenBSD 4.7	64	qemu-kvm-0.12.5	Intel	64	Works	Need e1000 driver. (scsi driver does not work). Ide works out of the box. disabling the mpbios is not needed. Done with Linux 2.6.34.2 host kernel.
OpenBSD 4.6	32, 64	qemu-kvm-0.11.0-0ubuntu6.3	Intel	64	Works	Need e1000 driver and disable mpbios (same as other OpenBSD >= 4.5 entries)
OpenBSD 4.6	32	kvm-84-7.6	AMD	32	Works	Use the e1000 driver [-net nic,model=e1000]. Does not find the network after the installation (during install is fine) but disabling mpbios as suggested in 4.5 workaround fixes it.
OpenBSD 4.5	32	kvm-85	Intel	32	Crashes	Use the e1000 driver [-net nic,model=e1000] to avoid lockups and slow network speeds. Crashes after "setting tty flags" - Jaco van der Schyff 4.0 would hang on me at the same place if i booted /bsd.mp but not if i boot /bsd (uniprocessor kernel) - Buck 4.5 can be made to boot by disabling mpbios as described here; this is a workaround though, not a fix - Maxim
OpenBSD 4.5	64	kvm-84	Intel	64	Works	Use e1000 drivers. Install from CD works, but then you must do the following at the next boot prompt: "bsd -c", "disable mpbios", then "quit" Make this permanent by using "config -ef /bsd" as root, once everything has booted. -- Garry Dolley

NetBSD 3.1	32	kvm-21	AMD	64	Works
NetBSD 4.0	32	kvm-60	Intel	64	Works	avoid hangup on boot with --no-acpi and network card timeout by trying out a different card, e.g. -net nic,model=ne2k_pci
NetBSD 5.0	64	kvm-88	Intel	64	Crashes/hangs	Install CD image will crash or hang, depending on if ACPI is enabled or not. NetBSD 4.0 workarounds ineffective.
NetBSD 5.0.2	32	kvm from 2.6.32-2-amd64 debian kernel on debian sid	both Intel and Amd	64	Works	avoid slow down/ hangs with --no-acpi and network timeout by using -net nic,model=ne2k_pci, disable both SMP and ACPI in /boot.cfg inside guest
MirBSD 2009/10	32	kvm_1:84+dfsg-0ubuntu12.4~hardy1	Intel	Works	Use of nic,model=e1000 is strongly recommended, ne2k variants work too, emulated Realtek are crappier than metal ones and do not work.
PC-BSD 1.4	32	kvm-56	Intel	64	Works	By Alexey.E.
DragonflyBSD 1.10.1	32	kvm-58	Intel	64	Works	avoid kvm-[64-67] which require -no-kvm-pit to work; use -net nic,model=e1000 to avoid network timeouts

UNIX Family: Solaris/OpenSolaris

Guest	Guest bitness	Host version	Host cpu	Host bitness	Status	Comments
Solaris 10 U1	32	kvm-12	Intel	64	Works	later releases will detect the CPU is 64 bit capable and try to default to run a 64 bit kernel and fail, for those you have to override Solaris autodetection by adding "kernel/unix" to the kernel multiboot entry in GRUB
Solaris 10 U3	64	kvm-58 + patch	Intel	64	Works	needs additional patch to kvm for kvm kernel longmode
Nexenta Core 1.0	64	kvm-61	Intel	64	Works	needs additional patch to kvm for kvm kernel longmode. Use -m 512 -net nic,model=e1000
Nexenta Core 2.0 b104 rc3	32 / 64	qemu-kvm-0.11.0	Intel	64	Works	Might need additional patch to kvm for kvm kernel longmode. My qemu-kvm was already patched. Had to switch of 'acpi', 'apic' and 'pae' features in guest configuration. Guest machine-type set to pc-0.10. Use -m 512 -net nic,model=e1000.
OpenSolaris 2008.05	64	kvm-69	Intel	64	Works	Use -m 512 -net nic,model=e1000
Milax 0.3.2	32	kvm-62	Intel	64	Works	Use the kvm option -net nic,model=rtl8139 and add atapi-cd-dma-enabled=0,atapi-other-dma-enabled=0 to the kernel line in the grub menu for older releases of Milax http://www.milax.org/ in version 0.3.2 choose the Qemu grub menu entry ; tested on Ubuntu 8.04.1 by BerndSchemmer
Belenix 0.7.1	64	kvm-62	Intel	64	Works	Note: older releases of Belenix only work in text mode; tested on Ubuntu 8.04.1 by BerndSchemmer
Solaris 10 U6	32 & 64	kvm-62	Intel	64	Mostly Works (see note)	Note: the grub menu entry for Solaris 10 created by the installer is wrong, to make it work add kernel/unix to the line beginning with kernel ; tested on Ubuntu 8.04.1 by BerndSchemmer
OpenSolaris 2008.11	64	kvm-62	Intel	64	Works	tested on Ubuntu 8.04.1 by BerndSchemmer
OpenSolaris 2009.06	32, 64	qemu-kvm-0.11.0-0ubuntu6.3	Intel	64	Works	Used "-vga std" but don't recall why.
Solaris 11 Express 2010.11	32, 64	qemu-kvm-0.12.1.2-2.113.el6_0.8	Intel	64	Works but without USB support	During boot the system prints the following warning: "No SOF interrupts have been received. This USB EHCI controller is unusable." As a result, no keyboard and mouse functionality from the console. Must install with automatic networking enabled, and login via the network to use it. Also warns at boot "rtls0: Failure resetting PHY" but networking seems to still work.
OpenIndiana Build 151a (Desktop)	64	qemu-kvm-0.12.5+dfsg-5+squeeze	Intel Core i7	64	Works	During boot the system prints the following warning: "No SOF interrupts have been received. This USB EHCI controller is unusable." However, the mouse and keyboard work fine via the VNC console. Also warns at boot "rtls0: Failure resetting PHY" but networking works fine. Installed using "Solaris -> OpenSolaris" settings in virt-manager.
