NoHCL0 ABD support

If you are told by support that your Xen environment cannot support the Quadric Software ABD due to a bug in your XenServer release, please apply these steps to deploy a specialized version of the ABD that has no console (no "HC0").

1. Download the special ABD template from http://www.quadricsoftware.com/download/a2/agent_nohc0_a2_61.dat.gz
2. Open a SCP (e.g. WinSCP) session to your A2, logging as "alike"
3. Navigate to /home/alike/Alike/ext
4. copy the .gz file downloaded above to this area
5. Log into your A2 console (via SSH or console) and use option 4 to drop to shell
6. cd /home/alike/Alike/ext
7. mv 12.1.7620.dat OLDIMAGE.old
8. gunzip agent_nohc0_a2_61.dat.gz
9. mv agent_nohc0_a2_61.dat 12.1.7620.dat

Next, redeploy your ABDs and retest with ABD diagnostic jobs.
