Issue and Background
The administrator encountered the error at the end of the Machine Catalog setup of “The master VM: “xxxx.vm/CTX.xxxxxxx.date.snapshot”, has an invalid configuration”. A rather obscure and vague error merely eludes to an issue with the VM.
Root Cause and Resolution
Citrix Machine Creation Services (MCS) cannot provision machines from a master image if the OS/C drive disk isn’t in the 0:0 SCSI controller position.
Edit the master VM while it is offline on the hypervisor and adjust the SCSI controller C drive disk to 0:0 per the example below in VMware.
Special thanks to our Reubin Huckle for his quick diagnosis of the issue.
