Citrix XenServer 6.5 Service Pack 1

At Citrix Synergy, Mark T announces the availability of Citrix XenServer 6.5 Service Pack 1.
This is an important step for Citrix and shows the value of how Citrix is supporting their Hypervisor.

From my view its great to see Intel GVT-d joins the GPU pass-through which NVIDIA have been doing for a long time. NVIDIA is the leader of GPU for desktop/server virtualization and with NVIDIA GRID vGPU density makes it more affordable for every business.

NVIDIA GPU pass-through for Linux VM’s is now supported, great move and needed for Virtual Desktop Agent for Linux so you can connect to a GPU enabled desktop that is virtualized on Citrix XenServer

Service Pack 3 is a 379MB file, so it contains lots of hotfixes 🙂

Your map of Australia is wrong. You have put the state of Victoria inside the West Australian state.
