I'm using Xen 3.0.3 as packaged within CentOS 5 as my Dom0 system. I
was able to easily get the system to talk to our SAN and then use RAID
level "multipath" to group the multiple paths to the SAN into one
/dev/md0 which I then sliced up with LVM into: /dev/xenstore/Zimbra-root
and /dev/xenstore/Zimbra-swap. Zimbra-root is 500 gigs (which I
recently found out won't work because of the Bochs BIOS in Xen's HVM
version of QEMU) and Zimbra-swap is 16 gigs. When I boot up off of my
RHEL 4.5 iso, the installer boots, but then says that no hard drives
were found. Now I'm aware that there are massive changes being made to
the config files, but since this is 3.0 I suspect the old Python style
configs are still valid. Here's what I have to present my Dom0 logical
volumes to the DomU:
disk = [ 'phy:xenstore/Zimbra-root,hda1,w',
'phy:xenstore/Zimbra-swap,hda2,w' ]
I've tried different iterations of that as well with Zimbra-root as hda
and Zimbra-swap as hdb, as well as trying to present them as sda or sda1
and sdb or sda2. Nothing seems to work.
Here's my full config:
----------
import os, re
arch = os.uname()[4]
if re.search('64', arch):
arch_libdir = 'lib64'
else:
arch_libdir = 'lib'
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 4096
shadow_memory = 8
name = "Zimbra"
vcpus=2
pae=1
vif = [ 'type=ioemu, mac=00:16:3e:03:00:00, bridge=xenbr0, model=ne2k_pci' ]
disk = [ 'phy:xenstore/Zimbra-root,hda1,w',
'phy:xenstore/Zimbra-swap,hda2,w' ]
disk = [ 'file:/usr/src/RHEL4-U5-x86_64-AS-disc1.iso,hdc:cdrom,r' ]
root = "/dev/hda1 ro"
extra = "selinux=0 3"
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
boot="dca"
sdl=0
vnc=1
stdvga=0
serial='pty'
usb=1
usbdevice='tablet'
----------
The hardware it's running on is an HP DL380 G5 with dual 64-bit Intel
Xeons with multiple cores and 8 gigs of RAM. The eventual goal is to
run RHEL with Zimbra on it and a few other DomUs as well. I'm pretty
sure my problem here is simply one of not quite having the right syntax
for the disk config.
Thanks,
George
