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

I'm not sure if Artyom has submitted all his patches to QEMU yet.

This stuff is in. Definitely worked at 0.13 - 0.14 times, but I never
had time to check 0.15+.

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)

That 2009 blog is outdated: QEMU now lives in
git://git.qemu.org/qemu.git
and should be at 0.15.93 (1.0-rc3). Compare http://qemu.org for details.

CC'ed sparc maintainer and Artyom.

Andesas tks for the info.
upgrading to 0.15.1 did not solve the issue.

Adding some info:

Regards!

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

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

I'd guess these geometry parameters are not correct for your 12G disk.
It's strange though that the installer kernel sees different geometry
from the normal boot kernel.

5) echo
'partition="QEMU12.0G":disk="QEMU12.0G":ctlr=SCSI:2=0,25165824:0=0,20971520:6=40960,4194304'

/etc/format.dat

These could also be wrong, but I have no idea what the numbers mean.

In order not to mess with all this numbers I used a pre-defined 1.3G
disk in the Solaris format utility and created it with dd:
dd if=/dev/zero of=$1  bs=10k count=133756


Otherwise, Ignacio, are you sure that disk0 is your root FS disk and
not something else? Can you post your qemu command line?

qemu-system-sparc -M SS-5 -startdate "2009-12-13" -bios /root/ss5.bin -nographic -hda /root/imagenes/solaris.disk -hdb /root/solaris_2.5.1_1197.iso

Thks for your help Artyom. I'll try with a dd, and solaris format utility and I'll let u know

Ignacio
