# bunzip2 ttylinux-xen.bz2
# mv ttylinux-xen ttylinux.imgこれで、HDDのイメージができました。
"xmexample1"をコピーして、以下のように"/etc/xen/ttylinux.conf"を作ります。

# Python configuration setup for 'xm create'.
# This script sets the parameters used when a domain is created using 'xm create'.
# You use a separate script for each domain you want to create, or
# you can set the parameters for the domain on the xm command line.

#----------------------------------------------------------------------------
# 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.
disk = [ 'file:/root/ttylinux.img,sda1,w' ]
#----------------------------------------------------------------------------
# Set the kernel command line for the new domain.
# You only need to define the IP parameters and hostname if the domain's
# IP config doesn't, e.g. in ifcfg-eth0 or via DHCP.
# You can use 'extra' to set the runlevel and custom environment
# variables used by custom rc scripts (e.g. VMID=, usr= ).
# Set if you want dhcp to allocate the IP address.
#dhcp="dhcp"
# Set netmask.
#netmask=
# Set default gateway.
#gateway=
# Set the hostname.

# Root directory on the nfs server.
#nfs_root = '/full/path/to/root/directory'
# Sets runlevel 4.
extra = "4"
#----------------------------------------------------------------------------
# Set according to whether you want the domain restarted when it exits.
# The default is 'onreboot', which restarts the domain when it shuts down
# with exit code reboot.
# Other values are 'always', and 'never'.
#restart = 'onreboot'

起動してみます。

何度か試しましたが、いろんなところでハングアップします。
UNIX Magazine（2005年8月号）の記事をみますと、FedoraCore4のXenは、不安定だと書いてありますが、確かにそうでした。
