XenServer/DDK

Installation

1. Download Extract the xvda from the DDK ISO (ddk.iso)
2. Import the XVA (ova.xml) into XenServer
3. The VM should auto start after import (takes a while to import)
4. View the console and set the root password.

Installation as ESX VM

yes, I know, blasphemer and all that...

Still looking for a good way to convert it to OVF...

• Maybe: XenCenter Linux VM -> vCenter Converter -> ESXi Server [1]
• or http://didyourestart.blogspot.com/2013/03/convert-xenserver-xva-to-vmdk-for.html
• or http://www.mytechrants.com/converting-citrix-xva-file-to-microsoft-hyper-v-vhd/

My ugly ugly solution:

1. deploy XVA to Citrix and power on
2. create larger (10G+) ESX VMDK attached to running CentOS 5.9 VM
3. dd/netcat to ESX VM's secondary hdd
   • xen vm:

     dd if=/dev/xvda1 | nc [OTHERSERVER] 8000

   • esx vm

     nc -l 8000 | dd of=/dev/sda

4. fdisk, delete partition, recreate as full disk size, mark as bootable
5. expand file system

   resize2fs /dev/sda1

6. mount file system

   mount /dev/sda1 /mnt

7. reinstall grub on secondary drive

   grub-install --root-directory=/mnt /dev/sda

8. fix /etc/fstab and /boot/grub/grub.conf and change /dev/xvda1 to /dev/sda1
9. chroot to the file system and rebuild initrd

   chroot /mnt

   /sbin/mkinitrd /boot/hack.img 3.10.0+0

10. finally point grub to the new initrd /boot/hack.img
11. boot and profit... phew...

Version

DDK Based off of RedHat EL5.

XenServer DDK 6.2.0-70446c
Linux xenserver-ddk 2.6.32.43-0.4.1.xs1.8.0.835.170778xen #1 SMP Wed May 29 18:06:30 EDT 2013 i686 i686 i386 GNU/Linux

Second HDD

Perform an online resize:

1. With the DDK VM powered off, go to storage and edit the virtual disk
2. Increase the size (Ex. 20G)
3. Power on the VM
4. fdisk /dev/xvda
   • p d 1 n p 1 [enter] [enter] w
5. resize2fs /dev/xvda1
6. profit!

-- alternative method --

The DDK VM has minimal space free. Let's add a second for development room.

Add second virtual disk for data:

fdisk /dev/xvdc
# partition: n p 1 [enter] [enter] w
mkfs.ext3 -L /data /dev/xvdc1
mkdir -p /data
echo "/dev/xvdc1      /data           ext3    defaults,noatime 0 0" >> /etc/fstab
mount /data

mkdir /data/src
ln -s /data/src /root/.src

Note: You will end up with this error in yum if you don't add a second data disk:

Insufficient space in download directory

Yum Configuration

Disable broken Citrix repo:

sed -i "s/enabled=1/enabled=0/" /etc/yum.repos.d/Citrix.repo

This fixes this error:

# yum list
...
Could not retrieve mirrorlist http://updates.vmd.citrix.com/XenServer/6.4.93/domain0/mirrorlist error was
[Errno 14] HTTP Error 404: Not Found
Error: Cannot find a valid baseurl for repo: citrix

Exclude kernel from updates: (already built into /etc/yum.repos.d/CentOS-Base.repo, with "exclude=kernel-xen*, *xen*")

#echo "exclude=kernel-xen*, *xen*" >> /etc/yum.conf
echo "exclude=kernel*" >> /etc/yum.conf
