# Update the kernel on Rackspace Cloud Server

To change the kernel on a server hosted on Rackspace (using Debian) you just need to use aptitude as normal as always, but, If you want a 3.x kernel, it’s probably that you will get this error on your dmesg:

Then, apparently is a well know bug in Xen: debian bug and xen list then the solution is to add to /etc/fstab just like this:

/dev/xvda1 / ext3 defaults,errors=remount-ro,noatime,barrier=0 0 1

Well, that’s the only needed to fix it. Hope it help to someone.
