Kashyap,
I was unable to install any graphical environment on F21 Server.
Just "MATE Desktop" group install reports no such group and so on.
A couple of times F21 WKS failed with MAC address detection of RTL 8169 32-bit 
on new ASUS Board. Server did perfect,but . . . .
Thank you
Boris

 Subject: [Rdo-list] [Upcoming] Fedora 22 Virtualization Test Day on	16-APR-2015
 
 Heya,
 
 If you use Virtualization on Fedora for OpenStack development/test, and
 have a few spare cycles, you might want to participate in the upcoming
 (day after tomorrow) Virtualization test day for Fedora 22.
 
 Announcement[1] from fedora-virt list[1]:
 
   "A reminder that the Fedora 22 Virt Test Day is this coming Thu Apr
   16.  Check out the test day landing page:
   
   
https://fedoraproject.org/wiki/Test_Day:2015-04-16_Virtualization
   
   It's a great time to make sure your virt workflow is still working
   correctly with the latest packages in Fedora 22. No requirement to run
   through test cases on the wiki, just show up and let us know what
   works (or breaks).
   
   Updating to a development release of Fedora scares some people, but
   it's NOT required to help out with the test day: you can test the
   latest virt bits on the latest Fedora release courtesy of the
   virt-preview repo. For more details, as well as easy instructions on
   updating to Fedora 22, see:
   
  
https://fedoraproject.org/wiki/Test_Day:2015-04-16_Virtualization#What.27...
   
   Though running latest Fedora 22 on a physical machine is still
   preferred :)
   
   If you want to help out, pop into #fedora-test-day on Thursday and
   give us a shout!"
