------------------------------
Summary: VMware may fail to register VM if existing invalid VM is
registered
Key: VCL-977
URL: https://issues.apache.org/jira/browse/VCL-977
Project: VCL
Issue Type: Improvement
Components: vcld (backend)
Affects Versions: 2.4.2
Reporter: Andy Kurth
Fix For: 2.5
Under some circumstances a VM may become _invalid_. It looks like this:
VCL will fail to load a VM if an _invalid_ VM exists on the host that is using
the same .vmx file path as the new VM. As you can see in the image, there are
3 _invalid_ VMs all using the same computer, _vi1-154_. Each VM had been
loaded with a different image revision. If you attempt to load the same VM
with any of the same revisions, the VMware host would not allow the new VM to
be registered because it finds the existing _invalid_ VM using the same .vmx
path. The following appears in *vcld.log*:

The code is not detecting the existing _invalid_ VM because it is ignoring the
_Skipping invalid VM_ lines returned from {{vim-cmd vmsvc/getallvms}}:

The invalid VMs can be unregistered via {{vim-cmd vmsvc/unregister}}. The code
could be updated to try to unregister _invalid_ VMs if it fails to register a
.vmx file.
