VMWARE snapshot breaks cluster service

Hi,

We have VMWARWE ESX 3.5i running and we use VMWare converter to convert one of our servers into VM.  The server we converting is Windows2003 with cluster services.
Eveything is working fine after initial convert, then we tried rebooting like 3-4 times everything comes up fine.
2 issues:
1.  After installing VMWARE tools it breaks the cluster service and unable to start cluster.
2.  After taking a snapshot it breaks the cluster service also and unable to start cluster.

Issue 1 we can live without vmware tools, but issue #2 we need help figuring out.

If we delete the snapshot after, then boot up the server everything comes up fine.

Please help!

VMware supports MSCS in very specific configurations. Please look at the PDF on this site.

I personally do not recommend converting a cluster, but building it as outlined and migrating the services.

I agree with Stappmeyer, also I would not take a snapshot of a clustered server because you can really screw up the clustering service if you revert to a snapshot. The cluster service on the other server is expecting a specific time code and if you revert to your snapshot your counting will be off.
