Yes, it's still the same 6.7-stable, no change except for your patch and
recompiled ldomd.
The firmware version is this:
-> show /HOST hypervisor_version obp_version sysfw_version
/HOST
Properties:
hypervisor_version = Hypervisor 1.10.1.b 2011/09/12 09:56
obp_version = OpenBoot 4.33.1 2011/08/03 10:34
sysfw_version = Sun System Firmware 8.1.1.c 2011/09/12 10:53
(I got this machine from a liquidation sale so I haven't been able to get the
firmware update files, sadly.)

It's the same as in the previous mail, I'm just starting out on this machine.
domain "primary" {
vcpu 4
memory 4G
}
domain "obsd" {
vcpu 2
memory 2G
vdisk "/storage/vmimages/obsd.img"
vnet
}

This is the output of the command, both for the factory-default hv.md and the
"openbsd" hv.md:
# mdprint -q -g frag_space,frag_mblock factory-default/hv.md
frag_space (node 0x5de) {
bak <-- root (node 0x0)
fwd --> frag_mblock (node 0x5e2)
}
frag_mblock (node 0x5e2) {
base = 0x2a00000 /* 44040192 */
size = 0x6000000 /* 100663296 */
bak <-- frag_space (node 0x5de)
}
# mdprint -q -g frag_space,frag_mblock openbsd/hv.md
frag_space (node 0x12) {
fragsize = 0x800000 /* 8388608 */
bak <-- root (node 0x0)
fwd --> frag_mblock (node 0x17)
}
frag_mblock (node 0x17) {
base = 0x2a00000 /* 44040192 */
size = 0x6000000 /* 100663296 */
bak <-- frag_space (node 0x12)
}

I'll try to. I'll report back after upgrading to the latest snapshot.
