 +===== Detach a VHD from the Control Domain =====
 +
 +<note important>It is suggested to rename the REAL virtual disk so you DO NOT delete the wrong one!  Rename the real one because you can't rename the one connected to the control domain.  You can rename the REAL one back to the original name when you are done.</note>
 +
 +List out the VBD (connector object between VM and VDI) based on the VDI UUID:
 +
 +<file>
 +xe vdi-list | grep -B1 -A5 -i "part-of-vm-name"
 +
 +xe vdi-list name-label="<VDI-name-label>"
 +
 +xe vbd-list vdi-uuid=<UUID of VDI>
 +
 +</file>
 +<note important>Verify the VBD is the one connected to control domain!
 +</note>
 +
 +Once done, you want to first try to make VBD inactive (it may already be inactive),
 +
 +<file>
 +xe vbd-unplug uuid=<UUID of VBD>
 +</file>
 +
 +Once done, you can then break the connection:
 +
 +<file>
 +xe vbd-destroy uuid=<UUID of VBD>
 +</file>
 +
 +Check in XenCenter to verify and delete the virtual disk.

 +===== XenTools =====
 +
 +FIXME Incomplete and needs verification
 +
 +This is a procedure to fix XenTools networking issues:
 +
 +  - Remove network interface via XenCenter
 +  - Uninstall all Citrix XenTools packages from Add/Remove Programs
 +  - Remove Citrix from filesystem and registry
 +    * ''c:\program files\citrix''
 +    * ''c:\program files (x86)\citrix''
 +    * ''HKLM\Software\Citrix''
 +  - Run in an admin command shell
 +    * Stop all running XenTools services
 +    * ''sc delete xenlite''
 +    * ''winmgmt /resetrepository''
 +  - Reboot
 +  - Check things out and remove any 'ghosted' or hidden network adapters
 +  - Reboot again
 +  - Add network adapter in XenCenter
 +  - Reconfigure the networking until it works properly again
 +  - Reboot
 +  - Reinstall XenTools patiently
