Install Solaris (SNV 84) DomU at Xen 3.2 CentOS 5.1 Dom0 (64 bit)
This posting is targeting cloning Mercurial Repository for Xen 3.2 on CentOS 5.1 and creating 64-bit Xen 3.2 CentOS 5.1 Dom0. To verify Dom0 functionality Solaris
(Navada Build 84) has been installed as DomU. Xvnc has been set up per Sun manuals
and it appeared that only CDE Desktop was functional on DomU. Gnome Desktop
crashed immediately after logging in.
However , that’s quite enough to perform Oracle 10g R2 installation at DomU
and evaluate I/0 performance provided by new Xen Hypervisor for Solaris Paravirtual guests.
First install Xen 3.2 from mercurial repository on xen-disabled CentOS 5.1 instance
# cd /usr/src/
# hg clone http://xenbits.xensource.com/xen-3.2-testing.hg
# cd xen-3.2-testing.hg
# make world
# make install
Determine the name of the Xen Linux kernel version that was installed.
# ls /lib/modules
There should be a directory for the Xen Linux kernel (e.g., 2.6.18.8-xen)
Generate the module dependency list and map files
# /sbin/depmod 2.6.18.8-xen
Create the Xen initial ramdisk image
# /sbin/mkinitrd /boot/initrd-2.6.18.8-xen.img 2.6.18.8-xen
Disable tls
# mv /lib64/tls /lib64/tls.disabled
Set xend service to start
# /sbin/chkconfig --add xend
# /sbin/chkconfig xend on
Edit /boot/grub/grub.conf and copy one of the existing boot entries to make the
required changes for Xen and reboot into new kernel.
title Xen-3.2 x86_64 (2.6.18.8-xen)
root (hd1,4)
kernel /xen-3.2.gz
module /vmlinuz-2.6.18.8-xen ro root=/dev/VolGroup01/LogVol00 rhgb quiet

eth2 was reported by command "brctl show" as xen bridge
with virtual interface peth2 attached.
Create installation SNV84 DomU profile:-
# cat SNV84.install
name = "Solaris84pvm"
vcpus = 1
memory = "1024"
kernel = "/usr/lib/xen-solaris/unix-84"
ramdisk = "/usr/lib/xen-solaris/x86.miniroot-84"
extra = "/platform/i86xpv/kernel/amd64/unix - nowin -B install_media=cdrom"
disk = ['file:/usr/lib/xen-solaris/snv84.iso,6:cdrom,r','phy:/dev/sdb7,0,w']
vif = ['bridge=eth2']
on_shutdown = "destroy"
on_reboot = "destroy"
on_crash = "destroy"
# xm create -c SNV84.install
Runtime profile:-
name = "Solaris84pvm"
vcpus = 1
memory = "1024"
kernel = "/usr/lib/xen-solaris/unix-84"
ramdisk = "/usr/lib/xen-solaris/x86.miniroot-84"
extra = "/platform/i86xpv/kernel/amd64/unix"
disk = ['phy:/dev/sdb7,0,w']
vif = ['bridge=eth2']
root="/dev/dsk/c0d0s0"
on_shutdown = "destroy"
on_reboot = "destroy"
on_crash = "destroy"

P.S.
Jurgen Keil pointed my attention to CR 6631419 at opensolaris.org:-
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6631419
This CR contains workaround bringing Gnome Desktop back to life.
Run as root:-
for d in /usr/share/icons/*;
do
[-d $d ] && gtk-update-icon-cache --force $d;
done
