In the DevTest Portal under Monitor -> Virtual Service Environments -> VSE, no virtual Services were shown.
The vseDeploy/VSE_2013 folder in the DevTest showed several Virtual Services as .mar files.
When deploying a new Virtual Service it did not show this Virtual Service as .mar file in the vseDeploy folder.
Also stopping the VSE and then renaming the VSE_2013 folder to VSE_2013-backup, and restarting the VSE, did not create a new VSE_2013 folder.
Release : 10.1
Component : CA Service Virtualization
Searched the new Virtual Service with the following Linux command:
find / -name new-vs.mar -print
This found the new-vs.mar in a different vseDeploy location.
After stopping the VSE and copying all .mar files to the new vseDeploy location and starting the VSE again, all Virtual Services showed up in the Portal.
