While reading up on various scalable file systems I came across the sheepdog project. For those new to sheepdog, their website describes it as: “Sheepdog is a distributed storage system for QEMU/KVM. It provides highly available block level storage volumes that can be attached to QEMU/KVM virtual machines. Sheepdog scales to several hundreds nodes, and [...]

In my KVM presentation, I discussed how to create KVM guests using the virt-install utility. To create a KVM guest, you can run the virt-install utility with one or more options that control where the guest will be installed, how to install it, and how to structure the guest hardware profile . Here is one [...]
I read over the latest KVM putback log last night, and saw that KVM now supports booting from ISO images that are accessible via HTTP (it uses libcurl under the covers). This is pretty fricking cool, and allow you to boot in recovery mode without requiring local media or PXE, and provides a super easy [...]
I gave a talk last night on the Linux Kernel Virtual Machine (KVM) at the local Linux users group. The talk gives some background on KVM, and shows how to get KVM working on a server that supports processor virtualization extensions. The slides are available on my website, and I will try to get them [...]
During my KVM testing, I wanted to be able to use the virsh “console” command to access the console of my guests. This would make remote management a whole lot easier, since the default remote management interface (vnc) was a bit of overkill. To get virsh to allow me to console in, the first thing [...]
I have been playing around with libvirt, which is a virtualization toolkit that sits on top of the native virtualization technologies in various operating systems. Libvirt provides built-in support for managing remote nodes, which is useful when you need to enable one or more virtualization properties, or when you need to perform some type of [...]
