This also means that you'll currently need a PAE-disabled `dom0`. [[Stefan_Siegl|stesie]] is providing a PAE-disabled Linux kernel image at <http://brokenpipe.de/GnuHurd/XEN/>. - You can either get binaries at <http://youpibouh.thefreecat.org/hurd-xen/> or build them yourself. - Copy `gnumach-xen` and `hurd-modules` to your dom0 /boot. - Copy `hurd` into `/etc/xen`, edit it for fixing access to your hurd / and swap -- Run `xm create -c hurd`, gnumach should get started. + +## GNU/Hurd system + +/!\ You need an already installed GNU/Hurd system. + +If you have a free partition, you can fdisk to type 0x83, create a filesystem using: + + sudo mke2fs -b 4096 -I 128 -o hurd /dev/sda4 + +Replace /dev/sda4 with your partition.

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 |
