XenParavirtOps - Xen
What is paravirt_ops? paravirt_ops (pv-ops for short) is a piece of Linux kernel infrastructure to allow it to run paravirtualized on a hypervisor. It currently supports VMWare's VMI, Rusty's lguest, and most interestingly, Xen. The infrastructure allows you to compile a single kernel binary which will either boot native on bare hardware (or in hvm mode under Xen), or boot fully paravirtualized in
Hyperthreading - Xen
Needs Refactor Mixes Glossary, FAQ & HowTo elements Hyperthreading FAQ What is hyperthreading? Hyper-threading is the Intel technology name, and commonly known name, for the Computing concept known as simultaneous multithreading. AMD have an equivalent technology known as Cluster Multi-threading. Hyperthreading is a technology designed to improve the computational performance of superscalar proces
Improving block protocol scalability with persistent grants - Xen Project
The blkback/blkfront drivers developed by the original Xen team was lightweight and fast zero-copy protocol that has served well for many years. However, as the number of physical cores and the number of guests have increased on systems, we have begun to identify some bottlenecks to scalability. This prompted a recent improvement to the protocol, called “persistent grants”. This blog post will des
Xen Common Problems - Xen
This page contains answers to some common problems and questions about Xen. This list contains the most frequently asked questions. You may also want to check out the articles in Category:FAQ. Each section in this document links to further questions in other FAQ documents. General I'd like to contribute to the Xen Project wiki pages, I have something to add/edit/fix, how can I do it?

Why xen slides
by Apurv Awasthi, Sr. Technical Product Manager, AWS This session introduces the concepts of AWS Identity and Access Management (IAM) and walks through the tools and strategies you can use to control access to your AWS environment. We describe IAM users, groups, and roles and how to use them. We demonstrate how to create IAM users and roles, and grant them various types of permissions to access AW
PVH : PV Guest in HVM container
PVH allows a paravirtualized Linux guest to run in ring 0 by using a hardware-assisted virtualization technique called PVH. PVH combines aspects of para-virtualization (PV) and hardware virtualization (HVM) by using a PV entry point to boot the guest faster while still allowing the guest kernel to run in ring 0. Performance benchmarks show that PVH provides significant performance improvements ove
VT-dを使ってXenでPCI-Passthroughを設定する手順 at nkjmkzk.net
システム環境 CPU: Intel Core-i7 860 チップセット: Intel P55 Express マザーボード: MSI P55M-SD40 Xen: 3.4.0 dom0: Oracle VM Server (Oracle Enterprise Linux 5.3ベース) Passthrough対象のdomU: OpenSolaris b134 PVHVM Xenは既にインストールされているという前提で始めます。/etc/grub.confのkernel行に「iommu=pv」と追記してI/O Virtualizationを有効化します。＊これはBIOSでの有効とは異なります。BIOSでI/O Virtualizationを有効にした上でこの設定を行います。参考までにgrub.conf全体を。 default=0 timeout=5 splashimage=(hd0,0)/
