UEC: Windows instance on Lucid Lynx [HACK]

with 3 comments

Bundling Windows instances on UEC setup on Lucid Lynx (Ubuntu 10.04) was not as straight forward as it was with Karmic Koala (Ubuntu 9.10).  The steps for bundling, uploading and registering were the same as I mentioned here. The instance comes up nicely from pending to running state, acquires the public and private ip addresses.

Lo!!! there ends the similarity….

I wasn’t able to access the instance. No network connectivity….. neither PING nor RDP works. And this was frustrating!!!

As mentioned in my earlier post about UEC/Eucalyptus – Debugging instances, I tweaked the /usr/share/gen_kvm_libvirt_xml file on the Node Controller and added the VNC display option.

The outcome of this was surprising!!!!

When I connect to VNC, the following error stares at me….

Invalid BOOT.INI file
Booting from C:\WINDOWS
Windows could not start because of a computer disk hardware configuration problem.
Could not read from the selected boot disk. Check boot path and disk hardware.
Please check the windows documentation about hardware disk configuration

UEC/Eucalyptus – Debugging instances

with one comment

I have had an issue with my MS-Windows 2003 server instance raised on one of the Node Controllers (NC) on my UEC setup on Lucid Lynx( Ubuntu 10.04 ). The instance came up moving from pending state to running state as expected and my hybrid fox showed public and private IPs. However, I was not able to ping or RDP into the instance. The Windows image was custom bundled and tried and tested on my Karmic UEC setup, so I was quite puzzled as to why I was unable to connect to the instance. I wished I had the luxury of connecting to the instance for troubleshooting using VNC, like I normally do when I start a VM on KVM or Xen. A little bit of probing of the Eucalyptus files on NC proved useful. Here is the hack that helped me attach a VNC display to the instance and ultimately I could identify and fix the actual problem.

It is not safe to leave this option enabled on a production setup.
