boot.
eth0 will get IP from 10.xx.x.X range from the xenbr0 of the dom0
the default gw is 10.x.x.y1 ...the chottu machine running w/ one leg in xenbr0 (as eth1)
IP FORWARDING HAS been setup on chottu between xenbr0 (eth1) and br0 (eth2) interfaces - also IP_FORWARD is allowed. THUS, CHOTTU IS HOP + ROUTER
setup-alpine...take it till the end (i.e. choose xvda for install).
then fdisk /dev/xvda
delete the swap and root partitions.
create a new partition w/ ext4 for root (xvda2).
xvda1 should be boot (of circa 100 MB).
mount /dev/xvda2 /mnt
cd /mnt
mkdir boot
mkdir root
mount /dev/xvda1 ./boot
mount /dev/xvdb1 ./root
setup-disk -v -m sys /mnt
cd /mnt/boot/
mkdir grub
cd grub

poweroff.
------------------------------------------
change the XL CONFIG:
dharra [~/alpineInternal]# cat xen_config_alpineServer_RUNNING.xl
name = "alpineInternal_A"
# Kernel paths for install
kernel = "/usr/lib/xen/boot/pv-grub-x86_64.gz"

'/dev/mapper/sataAB_swap-internal_alp_A_VG3,raw,xvdc,rw',
###'/media/floppy/images/alpine-virt-3.7.0-x86_64.iso,raw,xvdd,devtype=cdrom,ro' ###hide this to boot in HVM w/o the cdrom
]
##domU settings

maxvcpus = 3
memory = 8192
vif = [ 'mac=xx:xx:xx:xx:xx:42, bridge=xenbr0' ]
on_reboot = 'restart'
on_crash = 'restart'
## scary name but it means domain is shut down.
on_poweroff = 'destroy'
### remote GUI
stdvga = 1

vncpasswd = "some_secure_shit"
======================
boot w/ the new XL config... VIOLA ... gets 10.20.1..IP adress and can reach internet.
dharra [~/alpineInternal]# xl list

======================================
cloning VM
lvcreate -L 40G -n sataAB_data-xen_VG2_P_Internal_A sataAB_data
....similarly for the other 2 volumes.
cp /etc/xen/alpine_Internal1_RUNNING.xl /etc/xen/alpine_Internal2_RUNNING.xl
edit Internal2 - mac/name/vnc address and CHANGE to NEW DISK
boot the new VM. Change /etc/hostname & /etc/network/interfaces (hostname here).
