Installing Ubuntu 14.04 LTS (Trusty Tahir) VM on a XenServer 6.2 host

I had a hard time getting Xenserver 6.2 to install a new VM with the latest long-term-support version of Ubuntu (14.04). The process documented below, pieced together from several posts, leads to a fairly straight-forward install.

Fix your pygrub on the Xenserver host

Based on this post, do the following:

  1. Login as root on your Xenserver host (dom0):

  2. Edit the file /usr/lib/python2.4/site-packages/grub/
    • Change line 428 from:

      if arg.strip() == "${saved_entry}":


      if arg.strip() == "${saved_entry}" or arg.strip() == "${next_entry}":

Apparently this is patched in the xenserver sources, but no idea why there's no update to the release yet.

Create a new VM template for XenCenter

Now, make a new template that you can use in XenCenter to create a Ubuntu Trusty VM.

  1. Login as root on your Xenserver host (dom0):

  2. Execute the following 3 commands:

    TEMPLATE_UUID=`xe template-list name-label="Ubuntu Lucid Lynx 10.04 (64-bit)" params=uuid --minimal`
    NEW_TEMPLATE_UUID=`xe vm-clone uuid=$TEMPLATE_UUID new-name-label="Ubuntu Trusty 14.04 (64-bit)"`
    xe template-param-set other-config:default_template=true other-config:debian-release=trusty uuid=$NEW_TEMPLATE_UUID

Create the VM from template using XenCenter

Now, run XenCenter on a Windows box, and go to VM -> New VM, and scroll down to this new template you created:


Next, when, prompted for install media, use the following URL:

And follow the remaining steps in the normal way.
