Welcome to the Newly Revised (and Revived) Xen Project Blog

After several days offline, the Xen Project blog has returned! Our blog had been subjected to malicious activities, so we had to take it down and remedy the situation. We’re back now, and although there are a few minor issues to address, we are ready to move forward. A few things you may notice: The […]

Xen & Docker: Made for Each Other!

By Olivier Lambert Containers and hypervisors are often seen as competing technologies – enemies even. But in reality the two technologies are complementary and increasingly used together by developers and admins. This recent Linux.com article talked about this supposed battle, noting however that developers are using Docker in traditional VMs to bolster security. Containers allow […]

Log Rotation and Syslog Forwarding

A Continuation of Root Disk Management First, this article is applicable to any sized XenServer deployment and secondly, it is a continuation off of my previous article regarding XenServer root disk maintenance.  The difference is that - for all XenServer deployments - the topic revolves specifically with that of Syslog: from tuning log rotation, specifying the amount of logs to retain, leveraging compression, and of course... Syslog forwarding. All of this is an effort to share tips to new (or seasoned) XenServer Administrators in the options available to ensure necessary Syslog data does not fill a XenServer root disk while ensuring - for...

Open Source and Code Signing

What is code signing   Code signing is the application of cryptographic hashes to code. Most people sign code in order to guarantee that no one has tampered with the code since publishing, and to explicitly be able to say that specific artifact originated somewhere. Most code signing relies on trusted third parties to effectively vouch for the identity of the signer.    Open Source   Code signing isn’t really new, even in the open source world. Most Linux distributions have been signing their packages for years. But Linux distributions are fortunate in many ways. They own everything from the kernel to user land applications, and...

XenServer Root Disk Maintenance

The Basis for a Problem UPDATE: Thanks to feedback from our community, I have added key notes and additional information to this article. For all that it does, XenServer has a tiny installation footprint: 1.2 GB (roughly).  That is the modern day equivalent of a 1.44" disk, really.  While the installation footprint is tiny, well, so is the "root/boot" partition that the XenServer installer creates: 4GB in size - no more, no less, and don't alter it!  The same is also true - during the install process - for the secondary partition that XenServer uses for upgrades and backups: The point is that this...
