For maximum benefit I suggest using the discussion page for page editing collaboration.
Firstly, some things on the current page aren't really clear, imho:
- "The standard arch kernel can be use to boot the domUs."
So, domUs can use the standard kernel?
- "In order for this to work one must add 'xen-blkfront' to the modules array in /etc/mkinitcpio.conf"
On the domUs?
- "The basic idea behind adding a domU is as follows. We must get the domU kernels (...)"
BUT one can also use a standard archlinux kernel? Maybe there is an inconsistency.
- Maybe someone more experienced can explain how to use encrypted (LUKS) filesystems with xen;
- Maybe someone more experienced can add a section on how to use other OSs like Microsoft® Windows&trade.
- I opt to delete the alternative installation method because experienced users can figure this stuff out for themselves and it might be horribly outdated;

Thirdly: This is incorrect - was stated before to be a frontend for Xen - it is NOT - it is a frontend for xenserver by citrix
this is also not for xen directly - it is for xen cloud platform which is something different afaik
- xvp is web interface and vnc proxy.
After installing xvp, you need to generate /etc/xvp.conf with xvpdiscover tool and adjust your web server for using /srv/http/xvpweb/.

Old section about build failures with dom0 kernel 2.6.31:
Please note: At the time of this writing (23.5.2010) the current version uses a patched kernel version 2.6.31, which won't compile using gcc 4.5.
The problem can be worked around by temporarily downgrading gcc and gcc-libs to version 4.4.3. It may also be needed to build the gmp4 package. You can possibly find gcc-4.4.3 and gcc-libs-4.4.3 on ARM (see Downgrading Packages)
pacman -Ud gcc-* yaourt -S gmp4 # not sure if this is really needed
Note: this didn't work for me (friesoft, 23.5.2010)
necessary modules on Dom0
You need to load xen-blkback in Dom0 for /dev/xvda* devices. If you didn't load it, the DomUs won't find the device for the root file systems.
Similarly, you need to load xen_netback for the network connections, else xm create will pause for quite a while and then abort with a message that it could not configure vif.
After struggling with the apparently outdated install info, I finally managed to dredge up this tidbit: https://bbs.archlinux.org/viewtopic.php?id=133220
The current instructions make it seem as though the AUR xen package will put a new kernel & img in /boot with Dom0 in the name. This is apparently not the case, as it seems to just re-use the existing kernel files (at least in x64 installs). Any chance someone more familiar with the subject could update the install instructions? Zootboy 23:39, 11 January 2012 (EST)
The standard i686 kernel cannot be used as Dom0 kernel
- This is true. The regular x86 (i686) Arch Kernel does not have Xen Dom0 support compiled in. I know that the x64 Kernel does have Dom0 support compiled in by default, and users are strongly encouraged to run Xen on a 64-bit host machine. It's good to have this section, but it should probably be reworked to explain better which Kernels have Xen Dom0 support and why. (I believe the LTS Kernel may have Dom0 compiled in the i686 version, but I'm not sure and I'm having trouble finding where I read that.) Zootboy (talk) 00:05, 28 May 2012 (UTC)
