Xen
Notes préliminaires pour la migration de vmWare à Xen...
==================================================
==================================================
Xen Virtualization
==================================================
==================================================
The machine needs to be prepared with LVM
a free partition on your harddrive which is partioned for LVM
and has usually a name lets name "mygreatlvmvolume"
You can make it with the pvcreate commando.
On my machine a pvscan give the following output:
PV /dev/sda5 VG mygreatlvmvolume lvm2 [372,52 GB / 45,29 GB free]
Then you can create within this partition a specific volume
lvcreate -n sme_lv -L 60GB mygreatlvmvolume <<<this creates an logical
volume where your sme installation will go inside.
mkfs -t ext3 /dev/mygreatlvmvolume/sme_lv
after this you type lvscan in your command prompt and this will show
something like this:
/dev/mygreatlvmvolume/sme_lv' [60,00 GB] inherit
==================================================
# create LVM With an empty space on the disk:
==================================================
# use tpe "Linux LVM" for "Physical Volume" (pv)
pvcreate /dev/sdb1
# Volumegroup on this Physical Volume (vg)
vgcreate mygreatlvmvolume /dev/sdb1
# Logical-Volumes inside your Volumegroup (lv)
lvcreate -n sme_lv -L 60GB mygreatlvmvolume
# format this volume
mkfs -t ext3 /dev/mygreatlvmvolume/sme_lv
==================================================
# Prepare for sme
==================================================
# To deal with the problem with
# "Could not find an installable distribution".
# replace http://distro/.ibiblio.org/pub/linux/distributions/smeserver/releases/7/...
# with "/mnt"
#Downloaded smeserver-7.4-i386.iso on /img
# http://distro.ibiblio.org/pub/linux/distributions/smeserver/releases/7/s...
mount /img/smeserver-7.4-i386.iso /mnt -o loop
# Create a VM with virt-manager (GUI) or virt-install
virt-install --paravirt --name hermes --ram 1024 --file /dev/vg0/hermes --nographics --location /mnt
==================================================
# RHEL5/CentOS5 box you can also do this which is a whole lot easier and quicker:
# /dev/main/sme => empty lvm
virt-install -n sme -r 512 -f /dev/main/sme \
-b xenbr0 --nographics -l \
