Hi All,
I "googled" extensively this error but nothing seemed to be similar to my case so I decided to post here.
I have a WORKING Server 2008 R2 64bit VM - it works fine in Fusion and in VMWare Workstation.
I want to Import it into an ESXi host with Converter but I get "Unable To Determine OS" error.
The log entry is not very helpful: "image processing task has failed methodfault exception sysimage fault unabletodetermineguestos"
What may be going on? Any suggestions?
I would really appreciate ANY help 
Thank you,
KK
