Install OpenSolaris 2008/05 DomU at Xen 3.2.1 CentOS 5.1 & Ubuntu 7.10 (Desktop) Dom0 (64-bit)



Install OpenSolaris 2008/05, based on Nevada build 86, requires workaround
recently suggested by Jurgen Keil ([1]). It's runtime profile differs from
reqular one due to utilizing ZFS filesystem (vs UFS for regular Nevada
builds) as was noticed by Mark Jonson at xen-discuss forum @opensolaris.org.
Place OpenSolaris 2008/05 DVD in drive, wait until gets mounted
and run:-



# dd if=/dev/hda of=/usr/lib/xen-solaris/os200805.iso



Then copy 64-bit xen-solaris kernel and x86.microroot to Dom0:-



mkdir -p /mnt01/tmp
mount -o loop,ro os200805.iso  /mnt01/tmp
cp /mnt01/tmp/boot/x86.microroot /usr/lib/xen-solaris/x86.microroot
cp /mnt01/tmp/boot/platform/i86xpv/kernel/amd64/unix /usr/lib/xen-solaris/unix-0805
umount /mnt01/tmp



Installation profile:-



name = "OpenSolaris"
vcpus = 1
memory = "1024"
kernel = "/usr/lib/xen-solaris/unix-0805"
ramdisk = "/usr/lib/xen-solaris/x86.microroot"
extra = "/platform/i86xpv/kernel/amd64/unix -kd - nowin -B install_media=cdrom"
disk = ['file:/usr/lib/xen-solaris/os200805.iso,6:cdrom,r','phy:/dev/sdb8,0,w']
vif = ['bridge=eth0']
on_shutdown = "destroy"
on_reboot = "destroy"
on_crash = "destroy"



During startup manage like in [1]:-



Welcome to kmdb
Loaded modules: [ unix krtld genunix ]
[0]> gnttab_init+0xce/W 403
gnttab_init+0xce: 0x3 = 0x403
[0]> :c



Login as jack/jack and follow [2] to perform
graphical install from Live CD to hard drive.
When graphical install ends don't click reboot.
Open root's terminal session,with password assigned by yourself
at installation startup, and run:-



# mdb -w /a/platform/i86xpv/kernel/amd64/unix
> gnttab_init+0xce?W 403
unix`gnttab_init+0xce: 0x403 = 0x403
> $q


# /usr/bin/scp -S /usr/bin/ssh /a/platform/i86xpv/kernel/amd64/unix \
> IP-ADDRESS-Dom0:/usr/lib/xen-solaris/unix-0805


# /usr/bin/scp -S /usr/bin/ssh /a/platform/i86pc/amd64/boot_archive \
> IP-ADDRESS-Dom0:/usr/lib/xen-solaris/boot_archive


bash-3.2# shutdown -y -i0 -g0



Runtime profile:-



name = "OpenSolaris"
vcpus = 1
memory = "1024"
kernel = "/usr/lib/xen-solaris/unix-0805"
ramdisk = "/usr/lib/xen-solaris/boot_archive"
extra = "/platform/i86xpv/kernel/amd64/unix -B zfs-bootfs=rpool/27"
disk = ['file:/usr/lib/xen-solaris/os200805.iso,6:cdrom,r','phy:/dev/sdb8,0,w']
vif = ['bridge=eth0']
on_shutdown = "destroy"
on_reboot = "destroy"
on_crash = "destroy"



Notice that patched kernel and boot_archive are already copied to Dom0.
Login as user, been created during graphical install,into domU and tune
vncserver startup in same way like after boot from Live CD ([2]).
Your environment may be picked up from another loaded just for several minutes Live CD's instance.


Snapshots:-















Same schema also works at Xen 3.2.1 Ubuntu 7.10 (Desktop) Dom0.
Pygrub may be used for original install , but still cannot help
at runtime (no ZFS support for pygrub in Xen 3.2.1)





Patching kernel and copy it along with boot_archive to Dom0:-








Starting up DomU:-
