XenAPINFS – Integrated with Glance
Introduction This blog entry demonstrates the XenAPINFS - Glance integration. The feature's blueprint can be found on launchpad. At the time of writing this document, the driver only supports XenServer type ovf images (these images are specially named vhd files compressed to a .tgz archive). The cinder driver is using the nova xenapi plugins to upload/download the images. I am also working on a general case, ...

XenServer 6.1, XCP 1.6 and OpenStack Folsom
OpenStack has recently released Folsom. Also, last week Citrix have released XenServer 6.1 and Xen.org have released XCP 1.6 beta. I think now is a great time to point out some of what Citrix has contributed to OpenStack Folsom: Support for XenServer 6.1, XCP 1.6 and xcp-xapi in Ubuntu 12.04 Boot from volume for XenServer and XCP Live migration, without the need for shared storage using XenServer 6.1 and XCP ...

Convert a raw image to XenServer – VHD
If your choice of hypervisor is XenServer, and using ext storage, the virtual disks are stored in vhd format. I would like to show how to convert a raw image to VHD format. The first option could be to use the qemu-img tool, specifying vpc format. This solution works, until you decide to snapshot that virtual disk. OpenStack itself is creating snapshots of downloaded images, so ...

OpenStack, Xen and XenServer: a match made in Heaven!
I am just back from XenSummit and the Citrix sponsored CloudOpen in San Diego. It was great hearing about all the new things happening with Xen and all things Cloud. If you missed XenSummit you can find the slides on slideshare and hopefully videos will be available soon. There was lots of OpenStack related news in many of the CloudOpen sessions, including the announcement from SUSE that they have an OpenStack distribution that supports Xen. For ...

VHD to OpenStack using a XAPI host plugin
Four steps to upload a VHD to OpenStack. The goal was to use an existing OpenStack XAPI plugin to upload a VHD to OpenStack. For this demo, I was using two XenServers, one controlled by OpenStack, and the other holding a stopped instance. See the introduction on YouTube: Part 1 - Intro Create a Glance Image First, an image needs to be created on glance. Log in to ...

Citrix OpenStack Team take part in Xen Document Day
OpenStack has great support for XenServer (and XCP), but one of the stumbling blocks has been the lack of documentation in some crucial areas. Over recent weeks we have made some great improvements to the documentation. Please take a look, but do let us know your ideas on where you would like us to focus our next efforts: http://docs.openstack.org/ For a closer look at what we have planned, ...

CloudStack Community Growth?
We spend a lot of time answering questions about CloudStack community growth and progress since donating CloudStack to the Apache Software Foundation in April of this year. While my gut reaction is to roll my eyes and say “Um, it’s only been 3 months!”, the reality is that the project has been picking up steam faster than anyone could have expected. We thought it was mainly press and ...
