Neporozumel jsem asi presne jak je to s tema serverama, ale budes-li mit ten prvni, tak doporucuju xen
Dom0 + DomU rooty na ten raid 1 (73.4G scsi)
Veskera user data na ten raid5 (patrne planujes 5ku)

# Example Python setup script for Debian guest installation.
#============================================================================
#
# Standard options are configured as normal. Only a subset are included below.
# See /usr/share/doc/xen-utils-common/examples for full examples.
#
# After standard options are configure use
# xm create xm-debian.cfg install=true"
# to start the Debian Installer.
#
# In the installation case the following additional variables exist:
#
# COMMON OPTIONS
# install-method: "cdrom" or "network"
# install-arch: which architecture to install. e.g. i386 or amd64
# install-installer: URL or path to the Debian Installer bits. By
# default for a network install these are located under
# install-mirror. For a CDROM install the default is a fixed path on
# the CD.
# install-kernel, install-ramdisk: URL/path to the installer kernel and
# ramdisk to use, by default these are located via install-installer.
# install-extra: extra command line arguments
#
# CDROM SPECIFIC OPTIONS
# install-media: Path to the Debian install media (i.e. an ISO)
# install-cdrom-device: Name of the CD-ROM device within the guest.
#
# NETWORK SPECIFIC OPTIONS
# install-suite: which Debian version to install. e.g. lenny, squeeze or sid
# install-mirror: which Debian mirror to use
# e.g. http://ftp.uk.debian.org/debian
#============================================================================
## launching command:
# xm create xm-debian.cfg install=true install-method=network install-arch=i386 install-suite=lenny install-mirror=http://ftp.cz.debian.org/debian/ install-kernel=/var/xen/boot/vmlinuz-lenny install-ramdisk=/var/xen/boot/initrd-lenny install-extra=" DEBIAN_FRONTEND=newt "

# Standard variables
# Initial memory allocation (in megabytes) for the new domain.
memory = 256

# on each call to 'xm create'.

#----------------------------------------------------------------------------
# Define network interfaces.
# By default, no network interfaces are configured. You may have one created
# with sensible defaults using an empty vif clause:
#
# vif = ['']
#
# or optionally override backend, bridge, ip, mac, script, type, or vifname:
#
# vif = ['mac=00:16:3e:00:00:11, bridge=xenbr0']
#
# or more than one interface may be configured:
#
# vif = ['', 'bridge=xenbr1']
vif = ['bridge=xenbr0']
#----------------------------------------------------------------------------
# Define the disk devices you want the domain to have access to, and
# what you want them accessible as.
# Each disk entry is of the form phy:UNAME,DEV,MODE
# where UNAME is the device, DEV is the device name the domain will see,
# and MODE is r for read-only, w for read-write.
#
# NB: Only xvd devices are supported by the kernel in Debian Lenny and later.
disk = ['phy:/dev/sdb8,xvda,w']
#----------------------------------------------------------------------------
# Define frame buffer device.
#
# By default, no frame buffer device is configured.
#
# To create one using the SDL backend and sensible defaults:
#
# vfb = [ 'type=sdl' ]
#
# This uses environment variables XAUTHORITY and DISPLAY. You
# can override that:
#
# vfb = [ 'type=sdl,xauthority=/home/bozo/.Xauthority,display=:1' ]
#
# To create one using the VNC backend and sensible defaults:
#
vfb = [ 'type=vnc,vncdisplay=11,vnclisten=0.0.0.0' ]
#
# The backend listens on 127.0.0.1 port 5900+N by default, where N is
# the domain ID. You can override both address and N:
#
# vfb = [ 'type=vnc,vnclisten=127.0.0.1,vncdisplay=1' ]
#
# Or you can bind the first unused port above 5900:
#
# vfb = [ 'type=vnc,vnclisten=0.0.0.0,vnunused=1' ]
#
# You can override the password:
#
# vfb = [ 'type=vnc,vncpasswd=MYPASSWD' ]
#
# Empty password disables authentication. Defaults to the vncpasswd
# configured in xend-config.sxp.
