Xen : OpenSolaris 2008.11 DomU running on a Linux Dom0

This post is a step by step explanation about how to get an OpenSolaris 2008.11 run as a Xen DomU on a Linux Dom0.
To follow this, you’ll need a Linux machine ready for Xen (I run Xen 3.3.0), with vncviewer installed.

This post doesn’t explain the basics of Xen, so you might want to start by learning Xen if you don’t already know a bit of it.

shell tip : identify broken symlinks

If you need to identify broken symlinks, you can do the following :
find -L . -type l

The -L options instructs find to follow symlinks when possible. Hence no “working symlink” will ever get returned as the targets won’t match -type l (meaning “file is a symlink”).

On the other hand, find will not be able to follow broken symlinks, so the information will be taken from the symlink itself and not from the non-existent or otherwise unreachable target. The -type l will then be a match and the broken symlink filename will be returned.

Broken symlinks

Case solved 😉

Thanks to the “Ferg’s Gaff” blog (especially the comments) for showing the way !

Ubuntu 8.04.1 : Xen 3.2 package broken ?

I’m trying to install xen on Ubuntu 8.04.1 and here is what I get :

spaghetti% sudo apt-get install ubuntu-xen-server
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
ubuntu-xen-server: Depends: python-xen-3.2 but it is not going to be installed
Depends: xen-utils-3.2 but it is not going to be installed
E: Broken packages

I’ve tried to follow the package dependencies but without success. As for now I’m growing tired of Ubuntu and I’m considering moving away to a more robust distribution … I’d be glad to hear your point of view about that too.

Backups : a personnal implementation

If you’ve been following my blog for a while, you might have seen posts about SSH, RSYNC, ZFS Snapshots and so on. This article aims at describing the big picture, and to explain how I’ve been using those tools and technologies to build my own home backup system.
