I do have a client with an EM12c on VMware. There are some issues with the timedrift, but it was minimal and they have been running successfully for 9 months now. I believe this client had more concerns as their main systems are HP-UX than the actual VM, but they signed off on the risk document and that was my main concern. If the client is willing to sign off on the risk of their choice for platform, then it's mostly up to me to eliminate as many of those risks as possible and address any problems as they arise.

Hans:
Great point on the time drift issues that can often plague virtualized environments (VMware, OVM, Hyper-V) etc. I can't tell you how many times we've seen what would normally be straightforward troubleshooting/diagnostics exercises get ugly real quick due to collections of related servers with offset system clocks.
On a related note, Blue Medora is currently beta testing a new Time Drift Plug-in for Oracle EM12c focused on detection of time issues vs a set of defined NTP servers, time drift related EM incidents, and Oracle BI Publisher reports that summarize any EM managed agents that are time drifting.
If anyone on mailing list has any interest in participating in the Time Drift Plug-in Beta feel free to shoot us a note at: beta_at_bluemedora.com.
Thanks, --Nathan
