Dom0: Arch Linux

DomU: Arch Linux

The problem seems to be that the DomU can't find the Video Card.

/etc/mkinit.conf (DomU)

# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run.  Advanced users may wish to specify all system modules
# in this array.  For instance:
#     MODULES="piix ide_disk reiserfs"
MODULES="xen-blkfront xen-fbfront xen-netfront xen-kbdfront"

# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image.  This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=""

# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way.  This is useful for config files.
FILES=""

# HOOKS
# This is the most important setting in this file.  The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
##   This setup specifies all modules in the MODULES setting above.
##   No raid, lvm2, or encrypted root is needed.
#    HOOKS="base"
#
##   This setup will autodetect all modules for your system and should
##   work as a sane default
#    HOOKS="base udev autodetect block filesystems"
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS="base udev block filesystems"
#
##   This setup assembles a pata mdadm array with an encrypted root FS.
##   Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
#    HOOKS="base udev block mdadm encrypt filesystems"
#
##   This setup loads an lvm2 volume group on a usb device.
#    HOOKS="base udev block lvm2 filesystems"
#
##   NOTE: If you have /usr on a separate partition, you MUST include the
#    usr, fsck and shutdown hooks.
HOOKS="base udev autodetect modconf block filesystems keyboard fsck"

# COMPRESSION
# Use this to compress the initramfs image. By default, gzip compression
# is used. Use 'cat' to create an uncompressed image.
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"
#COMPRESSION="lz4"

# COMPRESSION_OPTIONS
# Additional options for the compressor

  • Is your DomU a PV or a HVM? Are you trying any sort of VGA pass through? How are you expecting to see the screen (e.g., did you enable the vnc viewer)?

  • PV. No. I don't know what a VGA pass through is. I just I would just see the screen? And yes, I'd eventually use remmina from another computer.

It looks like I'll be going down this path too. I just acquired an AMD Athlon 5150 system, myself (Athlon 5150 with integrated Radeon HD 8400 graphics). I can't speak to Dom0/DomU being Arch Linux, but for straight Debian it looks like this is a solution:

    AMD/ATI Proprietary Driver
    https://wiki.debian.org/ATIProprietary

Googling "AMD/ATI Proprietary Driver" and "Arch Linux" yields these two promising pages:

    AMD Catalyst - ArchWiki - Arch Linux
    https://wiki.archlinux.org/index.php/AMD_Catalyst

    ATI - ArchWiki
    https://wiki.archlinux.org/index.php/ATI

  • AMD_Catalyst failed me so far. Trying out the open source drivers.

  • Same problem :( . They seem to only support older drivers.
