[Xen-users] configurations for domU installation

[kibirango moses <kibsmoses@xxxxxxxxx>]

Hullo Everybody 

I am trying to install slackware 13 as a guest OS on  VM and i am using Citrix Xen platform  and i am failing below are my steps

[root@virtualintranet /]# fdisk -l

Disk /dev/sda: 1998.2 GB, 1998233534464 bytes

255 heads, 63 sectors/track, 242938 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System

/dev/sda1   *           1         523     4194304   83  Linux

Partition 1 does not end on cylinder boundary.

/dev/sda2             523        1045     4194304   83  Linux

/dev/sda3            1045      242938  1943010845+  8e  Linux LVM

[root@virtualintranet local]# xe sr-create host-uuid=<>content-type=user name-label="Local SR" shared=false device-config:device=/dev/sda3 type=lvm

[root@virtualintranet local]# xe vm-install template="Other install media" new-name-label=PVG1

vm-uuid=xxxx

 [root@virtualintranet local]# xe vm-param-set uuid=xxxx  PV-bootloader="pygrub"

[root@virtualintranet local]# xe vm-param-set uuid=xxxx PV-args="console=tty0 xencons=tty

[root@virtualintranet local]# xe network-list

[root@virtualintranet local]# xe vif-create network-uuid=<> vm-uuid=<> mac=random device=0

I renamed the Volume group to XenVG

[root@virtualintranet slack]# lvcreate –L 50G root –n XenVG

[root@virtualintranet slack]# mkfs –t ext3 /dev/XenVG/root

[root@virtualintranet slack]# mount /dev/XenVg/root /xen

[root@virtualintranet slack]# lvcreate –L 1G swap –n XenVG

[root@virtualintranet slack]# mkswap /dev/XenVG/swap

[root@virtualintranet slack]# mount /dev/XenVg/root /xen

 

I then edited the /etc/fstab

[root@virtualintranet ]# mkdir  xen

[root@virtualintranet xen ]# mkdir  images

[root@virtualintranet xen ]# mkdir  domU

[root@virtualintranet xen]# mount /dev/XenVg/root /xen

The file ‘slackware.13-0.x86.20090904.img.tar.bz2’ is in the xen directory

[root@virtualintranet images]# bunzip2 slackware.13-0.x86.20090904.img.tar.bz2

 [root@virtualintranet images ]# tar xvf slackware.13-0.x86.20090904.img.tar

slackware.13-0.x86.img

slackware.13-0.x86.xen3.cfg

slackware.13-0.x86.xen3.pygrub.cfg

[root@virtualintranet sl]#

Edit the /etc/fstab file

[root@virtualintranet /]# cat etc/fstab

Booting the Guest OS
[root@virtualintranet xen ]# umount  domU/

[root@virtualintranet / ]# umount  xen/
# xe vm-start uuid= xxxx

[root@virtualintranet /]# xe vm-start uuid=xxxx

Caller not allowed to perform this operation.

message: illegal kernel path

How can I fix these Xen Guest Boot Problems and what other options can I have since slackware 13 does not support pygrub and grub2 .

Thanx
