+The interresting aspect of using {{Command|pygrub}} as ''bootloader'' instead of specifying a kernel and a ramdisk is that the linux kernel will be taken from the ''DomU'' virtual machine and not from the ''Dom0'' host. Obviously we will have to override that during the installation.
 Note that Enterprise Linux keeps track of the network interface MAC address, and you will get warnings when it changes. So do not forget to specify a MAC address in the ''vif'' parameter to avoid the default one which is random.

 There is no way to install directly from the CD-ROM or ''ISO'' in para-virtualized mode (''PVM''), so you have to copy the files somewhere.
-<br />The installer can get its packages in several way, but the easiest in my view is via the web. So we copy the content the 5 distribution CDs (or the DVD) on a web server. It can be done on the ''Dom0'' system, but it does not really matter.
