VGA device assignment - KVM
Assigning physical VGA adapters It would appear that assigning modern PCI/PCIe VGA adapters should not be any different from passing through normal PCI devices. But there are additional challenges to solve, specifically related to legacy VGA requirements and proprietary mechanisms to relocate I/O regions of the adapters. Moreover, some QEMU and SeaBIOS deficits contribute to the current situation

HOWTO VMGL - KVM
Most of these steps are covered in the README file in the vmgl tar ball Download VMGL from here install libXaw, libXext, libjpeg, libXmu devel files for your distro. Warning: compile problems from missing libraries do not stop the Makefile and so keep an eye of out for them as the compile flies by. On 64-bit, I had to download and patch tightvnc with the patches provided in extra/patches/Xvnc.patc
KVM
KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. Using KVM, one can run multiple virtual machines running unmodified Linux or Win
KSM - KVM
Kernel Samepage Merging KSM is a memory-saving de-duplication feature, that merges anonymous (private) pages (not pagecache ones). Although it started this way, KSM is currently suitable for more than Virtual Machine use, as it can be useful to any application which generates many instances of the same data Enabling KSM KSM only operates on those areas of address space which an application has adv
