Yes, its almost there. Check out http://www.virtualizationteam.com/microsoft/hyper-v/videos-on-the-new-version-of-hyper-v-and-hyper-v-server.html to find out a video of the new hyper-v Live migration. In addition, they had further more showed the different between the existing quick migration and the upcoming live migration. I thought it was definitely worth sharing. Enjoy, Virtualization Master Hi,

Thanks for reading and commenting! Greg K,

We use DRS set to “Fully Automated”. Being that DRS is dependent on vmotion, without either of these features I would guess (have not run without them) we would be plagued with performance complaints and would have had to move many VMs to a Physical platforms. In my opinion VMotion and DRS are vital to a successful virtual platform implementation and I would discourage against virtualizing with any solution that does not have comparable features.
