Here's a little howto get Ubuntu Hardy working as a domU under Opensolaris :)
This should be fairly applicable to other variants of opensolaris. We assume that you have a functioning xend for this article. See my other howto on how to achieve this.
If you already have a physical hardy machine, you can save some time. You can skip step 1 and 2.
Basically what we will do, is setup a fully virtualized (HVM) Hardy installation, create a disk image, debootstrap a base Ubuntu installation in to this disk image and setup this disk image to be used under Xen.
Lets get started....
* Use virt-install to create fully virtualized (HVM) Ubuntu hardy install. You can also use the server or alternative installation media and text mode if you wish, the rest of the information in this howto is not specific to any of them.
* Use vncviewer to connect to your newly created VM and install Ubuntu as per normal. Once it is installed, login to the VM and open up a terminal.
* Create a sparse file to use as the disk image for the paravirtualized install of Ubuntu (you can use mkfile -n on solaris, but no such luxury exists in linux). Here we create a 20GB sparse file (which only actually uses up space as we add data to it). We'll also make a 2GB swap file that we can use later.
* Create an ext3 file system on the sparse file.
* Create swap space by running mkswap on our swap image
* Lets now loopback mount our file system.
* All looking good?
* Now we need to install debootstrap, which is a utility to install a base debian/ubuntu system.
* Lets use debootstrap to setup our base system. Be sure to use a mirror geographically close to you so its faster.
* Lets change root in to our shiny new environment
* Edit the sources.list file to include hardy-updates. Unfortunately there is a bug in the default linux kernel shipped with hardy that will cause segfaults when bringing up a network interface - so we need to use the updated kernel from hardy-updates (see this bug - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/218126). Remember to use a mirror geographically close to you.
* Install our Xen enabled kernel, kernel modules, and the grub boot loader. Kernel image and modules are both pulled in as part of the linux-image-xen metapackage, so we only need to install it.
* Almost there! Now we setup our /etc/fstab file
* Setup the grub boot loader. It doesnt like xen kernels for some reason, and wont automagically create them. Normally making the /boot/grub directory and running update-grub is enough, but not in this case...
* Turn off the hwclock. We'll get our time from our host OS.
* Create an xvc0 tty for our xen console to talk to. We will just copy tty1 and replace any occurance of tty1 with xvc0 using sed.
* Setup our networking configuration
* Also setup our hosts file
* And one last file to create, our hostname
* Congratulations - your disk image is built! Only a few more easy steps.
* Exit the chroot environment
* Unmount our disk image
* Copy our two disk image files (remember creating swap waaay back in this howto?) back to our Xen dom0.
* You can now exit out of your fully virtualized (HVM) Ubuntu. Back on the Xen dom0, move the .img files to where you would like to store them permanently. I'll assume you want them in /vm/ here
* Create a suitable xen configuration file. Use a MAC address inside the range 00:16:3e:xx:xx:xx. This address range is reserved for use by Xen.
* Now to see if it all worked... Lets boot her up and connect to the console. If you see output like this, then its all worked! The formatting is a little messed up from my terminal.

* Lets change root in to our shiny new environment
# chroot /mnt # export LANG=C
* Edit the sources.list file to include hardy-updates. Unfortunately there is a bug in the default linux kernel shipped with hardy that will cause segfaults when bringing up a network interface - so we need to use the updated kernel from hardy-updates (see this bug - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/218126). Remember to use a mirror geographically close to you.

* Almost there! Now we setup our /etc/fstab file
# cat <<EOF >/etc/fstab > /dev/xvda1 / ext3 defaults 0 1 > /dev/xvdb1 none swap defaults 0 0 > proc /proc proc defaults 0 0 > EOF # cat /etc/fstab /dev/xvda1 / ext3 defaults 0 1 /dev/xvdb1 none swap defaults 0 0 proc /proc proc defaults 0 0
* Setup the grub boot loader. It doesnt like xen kernels for some reason, and wont automagically create them. Normally making the /boot/grub directory and running update-grub is enough, but not in this case...
# mkdir -p /boot/grub # update-grub # mv /boot/grub/menu.lst /boot/grub/menu.lst.bak # cat <<EOF >/boot/grub/menu.lst default 0 timeout 3 title Ubuntu 8.04, kernel 2.6.24-17-xen root (hd0,0) kernel /boot/vmlinuz-2.6.24-17-xen root=/dev/xvda1 ro console=xvc0 initrd /boot/initrd.img-2.6.24-17-xen EOF # cat /boot/grub/menu.lst default 0 timeout 3 title Ubuntu 8.04, kernel 2.6.24-17-xen root (hd0,0) kernel /boot/vmlinuz-2.6.24-17-xen root=/dev/xvda1 ro console=xvc0 initrd /boot/initrd.img-2.6.24-17-xen
* Turn off the hwclock. We'll get our time from our host OS.
# update-rc.d -f hwclockfirst remove # update-rc.d -f hwclock remove # rm /etc/udev/rules.d/85-hwclock.rules
* Create an xvc0 tty for our xen console to talk to. We will just copy tty1 and replace any occurance of tty1 with xvc0 using sed.
# cat /etc/event.d/tty1 | sed -e "s/tty1/xvc0/g" >/etc/event.d/xvc0
* Setup our networking configuration
# cat <<EOF >/etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp EOF # cat /etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp
* Also setup our hosts file
echo "127.0.0.1 localhost" >/etc/hosts
* And one last file to create, our hostname
echo "ubuntupvm" >/etc/hostname
* Congratulations - your disk image is built! Only a few more easy steps.
* Exit the chroot environment
# exit exit
* Unmount our disk image
# umount /mnt
* Copy our two disk image files (remember creating swap waaay back in this howto?) back to our Xen dom0.
scp /var/tmp/ubuntupvm.img /var/tmp/ubuntupvm-swap.img user@hostname:/var/tmp/
* You can now exit out of your fully virtualized (HVM) Ubuntu. Back on the Xen dom0, move the .img files to where you would like to store them permanently. I'll assume you want them in /vm/ here
# mv /var/tmp/ubuntupvm.img /var/tmp/ubuntupvm-swap.img /vm
* Create a suitable xen configuration file. Use a MAC address inside the range 00:16:3e:xx:xx:xx. This address range is reserved for use by Xen.
# cat <<EOF >/vm/ubuntupvm.cfg memory = 512 name = "ubuntupvm" vif = [ 'mac=00:16:3e:00:00:00' ] disk = [ 'file:/vm/ubuntupvm.img,xvda1,w','file:/vm/ubuntupvm-swap.img,xvdb1,w' ]
* Now to see if it all worked... Lets boot her up and connect to the console. If you see output like this, then its all worked! The formatting is a little messed up from my terminal.
# xm create -f /vm/ubuntupvm.cfg -c
