HOW TO RUN VIRTUAL  WINDOWS XP'S PC IN YOUR SOLARIS DESKTOP WITH QEMU:

Download Qemu and Kqemu from opensolaris.org

http://www.opensolaris.org/os/project/qemu/downloads/
Note: kqemu now supported down to Solaris 8/X86

Compile kernel kqemu 

kqemu is a kernel accelerator doc is available at: http://fabrice.bellard.free.fr/qemu/kqemu-doc.html

- Enter in kqemu src directory
# cd kqemu-1.3.0pre11__osol20070214

- Run make
# cp Makefile.opensolaris_i386 Makefile
# make
gmake -C common all

- Run make install
# make install
cp kqemu-solaris-i386 kqemu
/usr/sbin/install -f /usr/kernel/drv -m 755 -u root -g sys kqemu

( cd /dev ; /usr/sbin/mknod kqemu c `/usr/bin/grep kqemu /etc/name_to_major | /usr/bin/awk '{print $2}'` 0 )

- Check that kqemu is load into the kernel
# modinfo |grep kqemu
238 f977a000  19ec8 211   1  kqemu (kqemu accelerator v0.2)

WARNING: If you wish to run qemu as non-root user then check rights of /dev/kqemu

Install qemu package from opensolaris.org

# pkgadd -d ./SUNWqemu-0.8.2_cvs20070120_REV_2007.01.24-sol10-i386-opt.pkg

The following packages are available:
  1  SUNWqemu     qemu
                  (i386) 0.8.2__cvs20070120sat

Select package(s) you wish to process (or 'all' to process
all packages). (default: all) [?,??,q]: all
...
...

Create a disk image file with qemu

# /opt/SUNWqemu/bin/qemu-img create /var/qemu/disk1.img 4GB
Formating '/var/qemu/disk1.img', fmt=raw, size=4194304 kB
# chown jblanche /var/qemu/disk1.img

Start Qemu and Install Windows XP

- Insert your Windows XP's DVD/CD SP2

WARNING: Used CD With Windows XP SP2 or the installation will failed.

-  Start Quemu and boot on cdrom

[18] id
uid=18557(jblanche) gid=18557(jblanche)
[19] /opt/SUNWqemu/bin/qemu -m 512 -k fr -boot d -hda /var/qemu/disk1.img -cdrom /dev/dsk/c1t0d0s2

My cdrom is located on /dev/dsk/c1t0d0s2 my TOSHIBA M3 LabTop

- Follow Microsft Windows XP Install Program

Wait....a long long long time...
Windows XP will reboot and will Finish the installation

Start Windows XP after Windows Installation with Network user

By default QEMU used the user mode network stack (http://fabrice.bellard.free.fr/qemu/qemu-doc.html#SEC30) you don't need root priviledge to use the virtual network.
The QEMU VM behaves as if it was behind a firewall which blocks all incoming connections. The DHCP server assign addresses to the hosts starting from 10.0.2.15.
The Firewall address is 10.0.2.2 (Which is your Solaris hosts).
So you can simply communicate with Solaris using the 10.0.2.2 network address in Your Virtual Window's XP PC. See next example (telnet to solaris from Windows XP)

 # /opt/SUNWqemu/bin/qemu -m 512 -k fr -boot c -hda /var/qemu/disk1.img

How to share DATA between Solaris (host OS) and your Virtual Windows XP's PC (Guest OS)

You can start QEMU with -smb (http://fabrice.bellard.free.fr/qemu/qemu-doc.html#SEC10) option to share data with SMB.

When using the user mode network stack, activate a built-in SMB server so that Windows OSes can access to the host files in `dir' transparently. In the guest Windows OS, the line: 10.0.2.4 smbserver
Then `dir' can be accessed in `\\10.0.2.4\qemu'. Note that a SAMBA server must be installed on the host OS see following example:

qemu -m 512 -k fr -hda /var/qemu/disk1.img -smb /var/qemu/SMB

How To Use Internet In you Virtual Windows XP's PC (Guest OS)

With QEMU in user mode network stack there is nothing to do. Every ouput traffic from you Virtual Windows XP's PC (Guest OS) is send to the default router (10.0.2.2) and then QEMU will NAT all network traffic to the ouput Solaris Network Interface.
