GHOST Vulnerability

You probably have heard of the GHOST vulnerability aka CVE-2015-0235. This one impact the glibc, which is running on XenServer. But is it dangerous for your hosts? What it is all about You can read more details on this excellent blog post. Basically, a gethostbyname() call can be triggered with any kind of DNS resolving stuff. So, what are the attack vectors on a XenServer host? Small attack surface XenServer privilegied domain (dom0) is built to offer the smallest attack surface. That's also why it's a best practice to let your dom0 as is after the install. The Citrix official statement so far is:...

XenServer at FOSDEM

Having just released Creedence as XenServer 6.5, 2015 has definitely started off with a bang. In 2014 the focus for XenServer was on a platform refresh, and creating a solid platform for future work. For me, 2015 is about enabling the ecosystem to be successful with XenServer, and that's where FOSDEM comes in. For those unfamiliar with FOSDEM, it's the Free and Open Source Developers European Meeting, and many of the most influential projects will have strong representation. Many of those same projects have strong relationships with other hypervisors, but not necessarily with XenServer. For those projects, XenServer needs to...

Using Grub 2 as a bootloader for Xen PV guests on Debian Jessie

I recently wrote a blog post on using grub 2 as a Xen PV bootloader for work. See Using Grub 2 as a bootloader for Xen PV guests over on https://blog.xenproject.org. Rather than repeat the whole thing here I'll just briefly cover the stuff which is of interest for Debian users (if you want all full background and the stuff on building grub from source etc then see the original post). TL;DR: With Jessie, install grub-xen-host in your domain 0 and grub-xen in your PV guests then in your guest configuration, depending on whether you want a 32- or 64-bit PV guest write either: kernel = "/usr/lib/grub-xen/grub-i386-xen.bin" or kernel = "/usr/lib/grub-xen/grub-x86_64-xen.bin" (instead of bootloader = ......

XenServer Support Options

Now that Creedence has been released as XenServer 6.5, I'd like to take this opportunity to highlight where to obtain what level of support for your installation. Commercial Support Commercial support is available from Citrix and many of its partners. A commercial support contract is appropriate if you're running XenServer in a production environment, particularly if downtime is a critical component of your SLA. It's important to note that commercial support is only available if the deployment follows the Citrix deployment guidelines, uses third party components from the Citrix Ready Marketplace, and is operated in accordance with the terms of the commercial...
