==== Howto add a new Xen vm ====


First create /etc/xen-tools/partitions.d///hostname// containing something like the following:
[root]
size=6G
type=ext3
mountpoint=/
options=defaults,errors=remount-ro

[swap]
size=2G
type=swap

[home]
size=4G
type=ext3
mountpoint=/home
options=errors=remount-ro

[tmp]
size=4G
type=ext3
mountpoint=/tmp
options=nodev

[var]
size=4G
type=ext3
mountpoint=/var
options=defaults,errors=remount-ro



After that run xen-create-image --hostname //hostname// --dist lenny --memory 512Mb --partitions //hostname// --ip //designated IP// --gateway //gateway IP (usually XenServer IP)// --netmask //netmask// --broadcast //broadcast IP//


Few things to do before starting the vm:

Mount the created volumes and start a chroot:

mount /dev/mapper/xxx /mnt
chroot /mnt

You now want to install udev (into the chroot):
apt-get install udev

Perhaps set a root password you know:

passwd root

next few tasks should be done in the chroot as well:

modify /etc/inittab:

#1:2345:respawn:/sbin/getty 38400 tty1
# comment all /sbin/getty lines

 add:
1:2345:respawn:/sbin/getty 38400 hvc0


edit /etc/sysctl.conf

xen.independent_wallclock=1

followed by the command:

sysctl -p

this should already be done so check:
xen-tools.conf:x slower than LVM partitions, then specify a directory here and uncomment
xen-tools.conf:x LVM volume group here instead
xen-tools.conf:lvm = vg0

when you are done start the vm:
xm create /etc/xen/$host.cfg
xm list shows running vms
