Subject RE: XenServer nested on XenServer
Date Fri, 24 Jun 2016 07:54:03 GMT
Dear Paul

Thank you for your advice.
Is it XenServer on ESXi???

It is no problem that my aim is the resource reducation.
But there are many haedware limitation for ESXi.
It cannot install ESXi to my poor machines...

Regards
