Cloudstack: OS type & xenserver templates

I’ve been using cloudstack for circa a month now for virtualising Solaris workloads. It has been mostly working like a charm, once I applied the appropriate workarounds (cf. my relevant findings, courtesy of my IoannisB citrix identity). However one thing has been bugging me for some time:

# xe vm-list name-label=i-2-271-VM params=name-description
name-description ( RW) : Template which allows VM installation from install media

My Solaris VMs are launched using the generic Xenserver template. This is not really to my liking for two reasons. Firstly, I have to apply the viridian:false modification to the default template. Secondly, there is no reason to appreciate whether a VM is a Solaris one or not using the Xenserver CLI.

The fix is to have Cloudstack using the “Solaris 10 (experimental)” template for my Solaris workloads.

  1. Download the cloudstack source code and uncompress to a folder of your choice.
  2. Apply a rather simple diff to the file:
    $ diff
    > _xenServer600GuestOsMap.put("Sun Solaris 10(64-bit)", "Solaris 10 (experimental)");
    > _xenServer602GuestOsMap.put("Sun Solaris 10(64-bit)", "Solaris 10 (experimental)");
  3. Build the JAR files, per the instructions in the Cloudstack installation guide page 16. No need to build DEB or RPM packages
  4. Replace /usr/share/java/cloud-plugin-hypervisor-xen.jar with cloud-plugin-hypervisor-xen-4.0.0-incubating-SNAPSHOT.jar that was built in the step above
  5. Restart the management server.

Slashdot geeks may want to add a Step-6: Profit. Launch again a Solaris 10 64-bit template and enjoy:

# xe vm-list name-label=i-2-272-VM params=name-description
name-description ( RW) : Clones of this template will automatically provision their storage when first booted and then reconfigure themselves with the optimal settings for Solaris 10 (experimental).
