Xen users - Apr 2010 - how to install centos/rhel PV domU on debian dom0 ?

Hello

i''m using Xen mainly to virtualize debian domUs on debian dom0 (lenny +
xen 3.2.1 kernel package)

to install my debian DomUs, i use xen-tools with a .tar reference domU 
to create new debian domUs

i would like to install a paravirtualized (not HVM) Centos or Red Hat 
Enterprise domU by the standard install mode,  i mean with anaconda with 
cd-rom or .iso file media or via nfs/http/ftp server


it is possible to use LV to store centos/rh disk and swap ?


i would also like to use the CentoS / RHEL domU kernel using pygrub


how can i do that ?


thank for your help and tips about this.

Arnaud

Arnaud, I did several tutorials based on other (much longer) tutorials that
I still use. This one uses a disk image but you could modify it for an LV.
This uses a kickstart file to do a partially automated install of CentOS5
over the network.

Hello Grant

Thank you for your links / tutorials !
I have installed with success PV centos/rhel DomU with LV virtual disks 
instead of image file) + pygrub.

To do the graphical installation, i used a virtual frame buffer for the 
console.

i used a LV ''iso'' (with CentOS ISO) to do Hard Disk
Installation


sample config files

for CentOS installation
-----------------------
kernel = "/boot/vmlinuz-centos-install"
ramdisk = "/boot/initrd-centos-install"
name = "vmcentos"
memory = "512"
disk = [ ''phy:vg_xen/vmcentos-disk,xvda,w'', 
''phy:vg_xen/vmcentos-swap,xvdb,w'',''phy:vg_xen/iso,hda3,r''
]
vif = [ ''bridge=xenbr0'' ]
vfb = [ "type=vnc,vncpasswd=xxxxxxx,vnclisten=0.0.0.0,vncdisplay=1" ]
keymap="fr"
vcpus=1
on_reboot = ''restart''
on_crash = ''restart''
on_poweroff = ''destroy''


after CentOS installation
-------------------------
bootloader="/usr/lib/xen-3.2-1/bin/pygrub"
name = "vmcentos"
memory = "512"
disk = [ ''phy:vg_xen/vmcentos-disk,hda1,w'', 
''phy:vg_xen/vmcentos-swap,hda2,w'',''phy:vg_xen/iso,hda3,r''
]
vif = [ ''bridge=xenbr0'' ]
vfb = [ "type=vnc,vncpasswd=xxxxxxx,vnclisten=0.0.0.0,vncdisplay=1" ]
keymap="fr"
vcpus=1
on_reboot = ''restart''
on_crash = ''restart''
on_poweroff = ''destroy''
