The official Xen.org Press Release announcing Xen 3.3 has been posted here. There are many partner quotes in the release from Oracle, Novell, Intel, AMD, Sun, IBM, Fujitsu, Samsung, Neocleus, Citrix, SignaCert, etc and I encourage everyone in the community to take a look. I just got a
From Samuel Thibault: When having a look at how much CPU time is used when an HVM guest is idle, one can notice that the ioemu process used to permanently take something like 7%. This is because ioemu used to keep checking the content of the HVM video RAM for
From Samuel Thibault: The traditional way to configure a PV guest is to write in the configuration file the path to the kernel/initrd to be loaded. However, logically enough, these should be on the PV guest disk image, to allow them to be managed by the distribution installed
From Samuel Thibault: To provide HVM domains with virtual hardware, Xen uses a modified version of qemu, ioemu. It used to run in dom0 as a root process, since it needs to directly access disks and tap network. That poses both a problem of security, as the qemu
From Samuel Thibault: Domain 0 running a lot of components like physical device drivers, the domain builder, ioemu device models, PyGRUB, etc. has been worrisome from a security point of view, particularly since most of them run as root, and thus breaches there would potentially be disastrous. It also
I am currently working on the Xen.org Community Plans for 2009 Xen Summits and I wanted to share my thoughts with the community to get feedback on my ideas. In the past, Xen Summits have been held every 9 months with the majority of them being in North America.
From Dan Magenheimer at Oracle: Memory overcommit provides the ability for the sum of the physical memory allocated to all active domains to exceed the total physical memory on the system. For example, if your machine has 4GB of RAM and you want to run as many 1GB domains
Xen.org Community: As part of the Xen 3.3 release, I have asked the various development authors to supply me with information on their new features. Over the next few weeks, I will be posting their overviews to this blog to give everyone further information on the features in
Xen.org Community: As many of you are aware, I have been working the past few months to update the current Xen.org website to better target various users of the site as well as simplify the organization of the information. I have completed the web development and am now
