Last week, Linux kernel father Linus Torvalds announced the release of version 3.0 of the Linux Kernel. This release does not introduce any binary incompatibility neither major changes.
Virtualization.info already covered the 3.0 release with regards to the integration of both KVM and Xen in the mainline tree of the kernel sources.
For Xen, this release means no more patches to the Linux kernel in order to make Linux virtual machines run as guests. In fact, Xen is a Type-1 hypervisor, so hosted operating systems need to have proper support built-in to run smoothly on virtualized hardware. Until now, a substantial Linux kernel patch had to be applied in order to add this support in the linux guest.
KVM, instead, is a Type-2 hypervisor, which runs itself on top of and operating system.
A full list of Xen related changes in the Linux kernel can be found here on the Xen wiki.

Login to your Xenserver with ssh and create a iso folder
mkdir -p /var/opt/xen/iso_import
Then, create the ISO store like this
xe sr-create name-label=”Local ISO” type=iso device-config:location=/var/opt/xen/iso_import/ device-config:legacy_mode=true content-type=iso

If You want to install Debian Lenny, as defined VM, maybe is better to use Remote URL:

Ukoliko želite da iskoristite sve mogućnosti ubuntu servera na xen virtualizaciji potrebno je da se instalira xenserver-tools alatka. Međutim, montiranje slike diska i pokretanje instalacije ne pomaže.
Uradite po ovom uputstvu:

Jedna napomena je da će trebati mnogo više pažnje ukoliko imate više diskova. Tada treba voditi računa o njihovim identifikacijama.
Naravno, podrazumeva se da ste kreirali snepšut (snapshoot – slika trenutnog stanja).
Ukoliko imate problema možete iskoristiti i sledeće uputstvo za instalaciju ubunta na xen server:
