Once you have selected a mirror then you can download the Debian Installer kernel and initrd. The following instructions assume that you are using, substitute the mirror which you have selected or the name of your apt-cacher/mirror machine as appropriate. Alternatively you can simply use the (unofficial) service to automatically select a nearby mirror. In general you should select the mirror which is nearest to you. If you are not using your own mirror or a tool such as apt-cacher then you will need to choose a nearby mirror from Debian's list of worldwide mirrors. If you are installing lots of guests then you may find it beneficial to create a local mirror (which will require a large initial bandwidth investment) or install a caching proxy such as apt-cacher to reduce the number of external downloads. If you are only installing a single guest this has the advantage of only downloading exactly what is needed for the installation. After this Debian Installer will take over and you can install the guest direct from the network. You start by downloading a small (approximately 20MB) installer kernel and initrd which you boot as a PV guest. Workarounds are available to build an unofficial iso image that can be used to prevent the crash from occurring, as discussed in this Debian bug report and on the debian-user mailing list.Ī netboot installation is a quick and easy way to install Debian. There is an unpatched bug in the Linux kernel that causes the Bullseye (Debian 11.x) Debian Installer to crash when trying to install Debian 11.x in a Xen HVM DomU using official Debian installation media such as the debian-11.x.0-amd64-netinst.iso that can be downloaded here. Installing a Xen guest Debian Installer produces a fully configured Debian system without the need to setup things such as /etc/fstab by hand. You also end up with an installed system which is as similar as possible to a native Debian system installed via the same mechanisms.

The main benefit of using Debian Installer to install a Xen guest is that you are able to use all the technologies (like pre-seeding) which you are used to using on a native system. Debian Installer has supported netboot installation of Xen as a PV guests (both i386 and amd64) since Lenny (Debian 5.0) was released and has supported CD-ROM (and DVD, Blu-Ray etc) installations since Squeeze (Debian 6.0).

6.2 Development (testing and unstable) Linksĭebian Installer is the standard installer used to install Debian on native systems.
