+## Xen dom0, PAE-disabled hypervisor

/!\ Since GNU Mach doesn't handle PAE yet, you'll need a PAE-disabled hypervisor.
On Debian Lenny, for example, you can install xen-hypervisor-3.2-1-i386-nonpae.

-If you have a free partition, you can fdisk to type 0x83, create a filesystem using:

-Replace /dev/sda4 with your partition. Install and use crosshurd to setup a GNU/Hurd system on this partition.

This also means that you'll currently need a PAE-disabled `dom0`.

- If `xm` complains about networking (`vif could not be connected`), it's Xen scripts' fault, see Xen documentation for how to configure the network. The simplest way is network-bridge with fixed IPs (note that you need the bridge-utils package for this). You can also just disable networking by commenting the vif line in the config.
- If `xm` complains `Error: (2, 'Invalid kernel', 'xc_dom_compat_check: guest type xen-3.0-x86_32 not supported by xen kernel, sorry\n')`, you most probably have a PAE-enabled hypervisor, and you just need to install and boot non-PAE hypervisor and kernel.
+## Building from sources

If you want to generate these images, first get the `gnumach-1-branch-Xen-branch` branch from gnumach CVS.
Then look for "Ugly" in `kern/bootstrap.c`, how to generate `hurd-modules` is explained there, and you'll have to fix `EXT2FS_SIZE` and `LD_SO_SIZE` by hand.
Then use
