Set up Ubuntu 10.04 Server PV DomU at Xen 4.0 Dom0 (pvops 184.108.40.206 kernel) Dom0 on top of Ubuntu 10.04 Server « Xen Virtualization on Linux and Solaris The procedure bellow in general follows Thiago’s Martins submission  to xen-devel mailing list. However,sequence of steps has been changed and also option of pvops kernel build via make-kpkg was added , /dev/xen/evtchn device hard linked with with pvops kernel, git checkout procedure is more straight forward and one Change-set from xen-4.0-testing.hg back ported to Xen 4.0 to support grub2 notation ‘(hd0,1)’ specific for Ubuntu 10.04 aka Lucid Lynx. Several suggestions have been also made regarding to have libvirt ,virtinst and related packages to work with Xen 4.0 on 10.04 Server.
Building A Virtual Cluster with Xen (Part One) Published on Thursday, 20 July 2006 21:00 Written by Angel de Vicente Hits: 126656 XenLinux kernel 220.127.116.11 aka Suse under Xen 4.0.1 on top of Ubuntu 10.10 Desktop « Xen Virtualization on Linux and Solaris Following post is a brief instruction of port 18.104.22.168 xenified aka Suse kernel to Ubuntu 10.10 desktop , to support Dom0 under Xen 4.0.1. Vanilla 22.214.171.124 gets patched via Andrew Lyon’s rebased patch set xen-patches-2.6.34-5.tar.bz2. Kernel configuration is similar kernel-xen config on Suse’s 11.3 . Linux and Virtualization The Xen solutions including installing and configuring Dom0 and DomU are summarized here. This post will be updated when our solution changes. Only the latest tested stable solutions are listed here. LVM volumes as backing for DomU’s file system is an appealing solution to Xen VBD. LVM volumes can dynamically grow/shrink and snapshot.
Setting up Stable Xen Dom0 with Fedora: Xen 4.0.1 with Xenified Linux Kernel 126.96.36.199 in Fedora 12 This is the latest stable and recommended stable Xen Dom0 solution on Fedora 12. No serious bug found till now and we will fix the bugs by ourselves if some appears. It also works on Fedora 14 as well. It should not be hard to use this solution on other versions of Fedora or other Linux distribution. How to set up Xen Dom0 with Xenified Linux kernel in Fedora 12 will be introduced in this post. Configuring Xen 4.0.1 & 188.8.131.52 pvops kernel for stable networking with OpenIndiana/OpenSolaris PV Guests on top of Ubuntu 10.04.1 Server « Xen Virtualization on Linux and Solaris This post is targeting pvops kernel 184.108.40.206 configuration close to 220.127.116.11 aka Suse 11.3 Xenified kernel. This config by some reasons allows OpenSolaris134/OpenIndiana147 PV Guest obtain IP address pretty stable on systems Xen 4.0.1 & PVOPS like it happens on OpenSuse 11.3 with Xen Hypervisor upgraded up to 4.0.1 and the most recent XenLinux 18.104.22.168 kernel. PVOPS systems with mentioned bellow drivers hard linked to the kernel have permanent trouble with providing IP via DHCP request,issued by OSOL/OI_147 PV guest, to this guest at least through my experience. Actually , only xen-netback module loaded separately from kernel is important. I just tried to change traditional PVOPS config , working perfectly for Linux guests, a bit more then usual and see what happens.

Create MD5 hash¶ Here is an example with a user jack and password abc123 echo -n 'jack:Ganeti Remote API:abc123' | openssl md5 How to Setup Xen4 and pvops 2.6.32.x on CentOS 5.5 Setting up Xen4 has been tricky, because of the move to the latest Linux kernels with paravirt_ops . Compiling it on CentOS, which uses 2.6.18 kernel, and old toolset is a bit more challenging. The following are my notes for setting up Xen4 + pvops 2.6.32.x on CentOS 5.5 on BL460c blades . Important note : I couldn’t get Xen 4.0.1 release work on CentOS 5.5 on our blades.

After a discussion on the torservers mailing list about setting up lots of Tor bridges for people to use to connect with the network in areas where it is otherwise blocked, it struck me that I should probably write up how I set up a few back in February during the uprising in Egypt. Seeing as how I have a limited amount of bandwidth where I live for various reasons (most of all Verizon halting deployment of residential fibre) I've been making use of VPS companies and pushing certain tasks off of my network and onto other people's. I know... I know..
