hi all.

Im trying to run a solaris 2.5.1 vm acording the instructions of i found 
in this blog:
http://tyom.blogspot.com/2009/12/solaris-under-qemu-how-to.html#uds-search-results

compile my qemu with:
git clone git://git.savannah.nongnu.org/qemu.git
cd qemu
./configure --target-list=sparc-softmmu
make
(version 0.13.50)

Ive downloaded the ss5.bin bios (sparc station 5)) I have the solaris 
disk and i can do the installation but can't get the disk to boot.

I can boot from the cd, mount and check the /etc/system file it has the 
"set scsi_options=0x58" option i set to make it work, still not working:

Here is the output:

/ok boot disk0:d
Boot device: /iommu/sbus/espdma@5,8400000/esp@5,8800000/sd@0,0:d  File 
and args:

(sd1):
     corrupt label - bad geometry

     Label says 1310720 blocks, Drive says 883120 blocks

ufs
panic: vfs_mountroot: cannot mount root
rebooting...
Resetting ... /

maybe the disk is wrong
ive try several disk one following these instructions:
1) qemu-img create -f qcow2 file.qcow2 12G
2) Add -drive file=file.qcow2,unit=3 to your qemu startup
3) Boot single user
4) echo 
'disk_type="QEMU12.0G":ctlr=SCSI:ncyl=49152:acyl=0:pcyl=49152:nhead=16:nsect=32:rpm=7200' 
 >> /etc/format.dat
5) echo 
'partition="QEMU12.0G":disk="QEMU12.0G":ctlr=SCSI:2=0,25165824:0=0,20971520:6=40960,4194304' 
 >> /etc/format.dat
6) format -d c0t3d0 -t 'QEMU12.0G' then label, y, and quit
7) newfs /dev/dsk/c0t3d0s0 followed by y
