the failure of not mounting the root file system maybe 
a symptom of a failed iso copy.  However, it's entirely
possible that qemu is choking on the dma commands that
Solaris is sending down to the virtual driver, and
causing the problem.  There are some patches that Juergen
Keil posted in the archive which can probably help that
particular issue.

I looked at my start line and it looks like you have
both -hda solaris10, and solaris10 at the end of your
command line.  How about removing the trailing solaris10
and see how that goes.   I think you probably want to
add -localtime to the start command as well. Yes, you'll
probably see some RTC errors when Solaris starts, 
but I've gotten Solaris 10 to load with the CVS code
plus Solaris patches.

stop qemu, add the log entries from the monitor, and
continue?

Hi,

thanks a lot for your insight. I just pulled the source from CVS and
applied the mentioned patch but had no luck (tried running qemu both
with and without -isa). It keeps bumping on the "cannot mount root"
error and reboot automatically again and again.

Looking at the message output, it seems that there are problems when
mounting the root using the CDROM. I'll try to download the images again
and see how that goes.

Thanks a lot for your help.

Cheers,
Celso

Which patch?

Are you trying to install Solaris 9 x86, or Solaris 10 x86?

Looking at your screenshot image, it seems you're trying to install Solaris 9
x86.

I do see some slight differences between Solaris 9 and 10 x86, and qemu-cvs:

Solaris 9 x86 & qemu cvs "-pci" crashes with pci-ide timeout and abort 
error messages (with exactly the error messages that you've got).

Solaris 9 x86 & qemu cvs "-isa" works.

Solaris 9 x86 & qemu cvs "-pci" + attached ide.c patch works, and uses
ide hdd dma transfers. 


Solaris 10 x86 & qemu cvs "-pci" works, but complains that the ide controller
is not busmaster dma capable, so ide hdd pio transfers are used instead of
dma transfers.

Solaris 10 x86 & qemu cvs "-pci" + attached ide.c patch detects a pci busmaster
capable ide controller and uses ide dma transfers.


(Note tested by me, but reported to work:)  Solaris "next" x86 & qemu cvs
"-pci" + attached ide.c patch is able to use dma transfers for both the
ide hdd and the ide atapi cdrom.

Re: [Qemu-devel] Solaris (9 and 10) supported on 0.6.1?

[emuls]

Hello,

I install a Solaris 10 (03/05) on couple QEMUs from CVS 0.6.2
(Host FEDORA or CentOS) without huge problems (With or without
IDE patch). I tried both instalation from CD-ROM image and CD
(/dev/cdrom).

Issues:
1. If HOST is LINUX check your kernel (QEMU dont like some kernel
hacks to make LINUX kernel faster). What is your HOST OS ?

2. I found than on very fast mashines, if proccessor is faster
then 2Ghz, time insise Solaris 10 instalation is very deformed.
In places where Solaris must wait by default 30s it waits maximum
only 2 seconds. !!! Have anybody idea why ??? What hardware you
have ?  
I use a couple tricks to make instaltion faster:
1. I use only 125MB of memory on install time of first CD, this
will automaticly switch instalation to text mode. After system
will install first CD, use for next boot and instalaiton of rest
CDs 256MB of memory.

2. I use a network floppy image from
http://www.tools.de/solaris/itu/ and add driver in DCA (mount
floppy image du.ing as fda and press escape on begining of
instalation, after F4 add driver) I configure network in user
mode manualy (DHCP don't put right gateway or / and  DNS ?)
ne2000 driver works OK

3. I use a RAW format for hardrive image, QCOW with compression
is realtively slow if you use a CD image on same disk.

4. If you have a relativly slow proccessor you can in LINUX do:

renice -8 (pid of QEMU) 

It will speed up Solaris 10 instalation

[Qemu-devel] Solaris (9 and 10) supported on 0.6.1?

[Celso Pinto]

Hi everyone,

I noticed on the website that Solaris is a supported guest OS so I took a
shot at trying to install them without much luck.

The installed keeps panic-ing stating it cannot mount root (screenshot:
http://yimports.com/~cpinto/downloads/qemu/Screenshot-1.png).

I used the command:
% qemu -hda <img created for hda> -cdrom <iso for solaris install> -d
int,pcall -boot d <img created for hda>

but only an empty log file was created on /tmp. Is there any alternative
to provide more information about this issue?

Any thoughts?

Cheers,
Celso

Have you tried -isa option? IIRC this helped, but I'm not sure, certainly
if you grep the archive for solaris, you will find the right workaround.
