Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers


"With PD4 you can run 32-bit and 64-bit guests and allocate more than one CPU to a virtual machine, for a total of 8. To this VM you can attach 16 virtual NICs, 8GB of virtual memory, and virtual disks worth 2 terabytes.

"This is comparable to the virtual hardware you can generate with both Workstation and VirtualBox. Unfortunately, PD4 too skips the last bastion of VM connectivity -- there's no support for connecting FireWire devices. To add to its disadvantage, it also lacks any 3D capability which is now pretty much standard (albeit in beta form only) with the competition.

"If you think they couldn't have blown it any further, here's another hardware gotcha. PD4 supports Intel VT-x and AMD-V hardware virtualisation technologies. But unlike Workstation and VirtualBox, PD4 wouldn't run without these extensions. Although processors with these extensions aren't expensive, insisting on them locks out a huge mass that didn't read the fine print when upgrading to dual-core processors."
