What Are Your Thoughts On VirtualBox 5.0?

I've been using Parallels for quite some time now but just realised that I never gave VirtualBox 5.0 a proper test run.

VirtualBox 5.0 features

From the official release notes it seems there's lots of useful stuff:

  • Better Windows and Linux VM performance thanks for para-virtualization
  • Improved CPU utilisation – larger set of CPU instructions is now visible to each guest VM so you may see improvements if using recent enough software
  • USB 3.0 support – have to try this with one of my external HDDs
  • Disk image encryption – could be a useful alternative to built-in encryption of OS filesystems

Recent improvements in VirtualBox 5.0

And from the most recent VirtualBox 5.0 release (5.0.14), there seems ot be a few OSX related improvements:

  • fixed audio capture on OSX
  • proper limiting of vCPUs (not very relevant on my dual core laptop, I think)
  • several El Capitan related bugfixes

What do you think of VirtualBox 5.0?

So the questions are:

  1. What are your thougths on VirtualBox 5.0?
  2. Are you still using VirtualBox?
  3. Is primary use still desktop or are you looking at Docker containers or anything else server related?

Thanks for taking the time to comment, feel free to let me know on Twitter as well (@glebreys)

VDI with vGPUs

It seems the 3D acceleration is constantly getting improvements at different levels of virtualization.

As of VMware vSphere 6.0,  there's now a concept of Virtual GPU (vGPU). This is a technology that provides special direct access from a VM to the GPU hardware. Each ESX host is getting a NVIDIA's vGPU Manager installed which manages resource allocation for all the participating VMs.

NVIDIA developed a special class of GPUs for this, called NVIDIA GRID cards. Some of the cards can be shared among 16 VMs which is an impressive density. I believe you need to have a server hardware certified by NVIDIA as well, but it seems that all the major vendors are there (Dell, HP, Lenovo and even Supermicro).
