Subject RE: New capture failed atttempting Windows post-load tasks
Date Thu, 02 Aug 2012 20:37:53 GMT
Thanks Dmitri,

I was able to ssh to the vm from the management node before I captured. 

Curious.. because I never thought about it before... I can re-capture an existing vm that's
already been captured? I guess it makes logical sense. It's still just a vm existing in VMWare
Server. 

I'll give that a try.

Adam
