Host hardware: Intel Core 2 Duo, 8GB RAM, Intel graphics, wired Internet. Intel DQ45CB motherboard, Virtualization active.

Guests: One 64-bit MGA6, Plasma, tainted activated
        One 64-bit MGA6, Plasma, tainted inactive
        One 32-bit MGA6, Plasma, tainted activated

Used QA Repo to update all systems, using the package lists in the Description. 

Everything seems to work. I don't have any definitive benchmarks, but there seemed to be a significant improvement in startup/shutdown times. I'm taking that to indicate that virtualization is working where it didn't before.

mga6-32 (plasma) and mga6-64 (plasma) clients launched normally,
both with more than 1 CPU enabled. 
Previously I had to reduce the number of CPU's to one

updated vboxadditions and vboxvideo on mga6-32 and mga6-64 clients
both re-launched normally
no regressions noted

OK for mga6-64 on this system:

Host system 1: HP Probook 6550b, i3, 8GB RAM, Intel graphics, Intel wifi, 64-bit Plasma system.

Host system 2: Athlon X2 7750, 8GB RAM, nvidia340 graphics, atheros wifi, 64-bit Plasma system.

Each system has Mageia 6 guests, at least one 64-bit and one 32-bit, all Plasma.

Updated both hosts, and both guests on each host. No regressions noted. On this hardware, no particular visual difference in performance before and after the updates, either.

On real hardware, M6.1, Plasma, 64-bit
