Cloning and/or moving vMA is not supported by VMware, this has been the case since VIMA 1.0. If you take look at the "Known Issues" in the vMA release notes, you will see there is no still workaround. Users may find it useful to be able to clone vMA for backup purposes or to deploy another vMA without having to re-download or re-uploading .OVF from your local desktop/VMware's website.
If you ever tried to clone VIMA 1.0 and boot the system up, you will notice a warning message during the init process when vMA verifies the system's UUID. If it detects that it has been cloned, it will actually disable itself and makes the vMA components unusable until you reinitialize vMA using vimaclean. This is still the case with vMA 4.1, except the vMA components are no longer disabled when you perform a clone.
You will just see the warning message during the init process, but all functionality continues to work. Before the vMA specific components starts up, it makes a call to /opt/vmware/vma/bin/verifyuuid. It verifies the system UUID which you can extract using dmidecode, this is the same UUID found within the .vmx entry called uuid.bios. When you clone a VM, a new UUID will be generated which causes an issue when it tries to verify.
Prior to vMA 4.x, VIMA 1.0 stored all it's configurations within a set of XML files located in /etc/vmware/viconfig, these files held the config for both the vi-fastpass targets and vilogger config and policies. With the release of vMA 4.0, these configurations were migrated to a sqlite3 database which is stored in /var/opt/vmware/vMA/vMA.db. Within this database, it also stored as the old flat file configuration, the system UUID of vMA. This is what verifyuuid was checking against to see if it was cloned or moved, you can actually query the vMA DB to extract this information using a simple SQL query.
To resolve the warning message, you just need to update the new UUID in the vMA DB using an update statement.
Instead of manually typing all that out, I actually created a very simple script that queries for the current system UUID and then updates the vMA DB with the correct UUID. Here is a sample execution:
I suspect that VMware may have allowed cloning of vMA, but just did not update their release notes? The only thing you have to do is manually fix the UUID if you do not want to see the warning message. If you would like to fix this for VIMA 1.0, you will need to do the same thing except you need to modify the UUID found in /etc/vmware/viconfig/viconfig.xml and restart vMA for the changes to effect.
