Simple 12 steps for installing OpenSolaris 2008.05 into xVM or XEN VM in PARA mode, in

This entry is part of ‘OpenSolaris on Amazon EC2’ Workshop

For installing into XEN on Linux see more detail in discusion Installing OpenSolaris 2008/05 as a PV guest

1) Download OpenSolaris 200805 version for primary languages only (os200508.iso) it is compressed by GZIP, All languages GLOBO version (os200805g.iso) is compressed by LZMA and installation in xVM/XEN (or other virtualizations can be much slower)

2) Install OpenSolaris 200805 in xVM or XEN PARA mode

Get predefined fix mac address with prepared DHCP setup

 cat hostnames | grep xen-2
xen-2             00:16:3E:3f:fb:0f  Amazon AWS EC2 Virtualisation testing

Create 4GB root file

mkdir /stuff/os200805
mkfile 4g /stuff/os200805/osoljeos.img

We will use pygrub to boot xVM or XEN PARA kernel from CD-ROM

name = "inst-os200805"
vcpus = 1
memory = "1700"
bootloader = "/usr/lib/xen/bin/pygrub"
kernel = "/platform/i86xpv/kernel/amd64/unix"
ramdisk = "/boot/x86.microroot"
extra = "/platform/i86xpv/kernel/amd64/unix -B console=ttya,livemode=text"
disk = ['file:/stuff/os200805/os200805.iso,6:cdrom,r',
vif = ['mac=00:16:3E:3f:fb:0f']
on_shutdown = "destroy"
on_reboot = "destroy"
on_crash = "preserve"

xm create -c

3) Select languages

4) Login as jack/jack and switch to root

su - root

5) Check network connection and get IP

ifconfig xnf0
xnf0: flags=201004843<UP,BROADCAST,RUNNING,MULTICAST,DHCP,IPv4,CoS> mtu 1500 index 2
inet netmask fffffc00 broadcast
ether 0:16:3e:3f:fb:f

6) Installation is GUI only, we need for installation X display

I prefer to use remote X leaving more memory for OpenSolaris installation

6a) Use for installation vncserver

Exit root shell with


Start vncserver server

mkdir .vnc;cp .Xclients .vnc/xstartup
jack@opensolaris:~$ vncserver
You will require a password to access your desktops.
xauth:  creating new authority file /jack/.Xauthority
New 'opensolaris:1 ()' desktop is opensolaris:1
Starting applications specified in /jack/.vnc/xstartup
Log file is /jack/.vnc/opensolaris:1.log

Connect to desktop on VNC server


6b) Use for installation ssh with X redirection

ssh -X jack@
export DISPLAY=computer:0.0
pfexec gui-install

7) Select whole first disk and install

Whole 4Gb disk
root password: opensolaris
priv user: osol Passwd: osol0508
Important: Select UTC – England (UK) as time zone !

8) Click reboot

On Linux based XEN copy /platform dir to get Kernel/Ramdisk

xVM or XEN will destroy install VM

9) Boot just installed OpenSolaris 200805 VM

This will automaticaly use PyGRUB, on Linux based XEN use kernel/ramdisk from /platform dir

name = "os200805"
vcpus = 1
memory = "1700"
disk = ['file:/stuff/os200805/osoljeos.img,0,w']
vif = ['mac=00:16:3E:3f:fb:0f']
on_shutdown = "destroy"
on_reboot = "destroy"
on_crash = "preserve"

xm create -c

11) Disable X login (if don’t want it)

login as osol/osol0508
svcs -a | grep gdm
online         13:14:35 svc:/application/graphical-login/gdm:default
su - root
svcadm disable svc:/application/graphical-login/gdm:default

12a) Backup OSOL domU comfig

virsh dumpxml osol0508 >/stuff/osol0508/osol0508-boot.xml

12b) Halt system with init 0 and backup root file

Issue: Under PARA mode system time after boot start from1.1.1970, use ntpdate to fix it.

6574993 zfs_mountroot() may need to call clkset() to set the boot_time kstat
