Linode is cheaper than many of the other big names in VPS and they offer plenty of storage and bandwidth too. Monitoring their status page for a few days/weeks should give you a good idea of the kind of downtime you’ll be looking at.

10 tips, each summarized in a sentence or two. Speed up your WAN, Build a lab, know your apps, virtualization pitfalls, speed up backups, and more.

VirtualBox can’t operate in VMX root mode. Please disable the KVM kernel extension, recompile your kernel and reboot. You might see this VirtualBox error when trying to start a virtual machine or create a new one.

These two scripts are called when you start a qemu or kvm virtual machine. I removed the openvpn –mktun and –rmtun commands because qemu handles it for you.

So you want to setup networking so virtual machines will have access to the outside world through your hosts network connection. To do this you’ll need to share your host’s external interface with virtual machines through a bridge. A bridge can join two network segments and be used to inspect all Ethernet frames that pass between them. Create a bridge and a tunnel interface. Assign the tunnel and your host’s Ethernet interface to the bridge. Connect the bridge to the outside world. Your host uses the network card in promiscuous mode to handle packets for other interfaces connected to the bridge.

QEMU is a generic and open source machine emulator and virtualizer. When used as a machine emulator, QEMU can run OSes and programs made for one machine architecture on a different machine architecture. This is different than VMware, VirtualBox, or Hyper-V where you’re running different operating systems on the same architecture.

ATI eyefinity video cards support up to six displays and multiple cards can be used together in a single machine for a single virtual display. AMD says they’ll be able to chain together enough of their eyefinity cards to create a resolution that approaches eye-definition optical clarity at 12x 1080p.

Maybe i’m one of those minorities, but just last year’s Surrogates movie showed the darker side of avatars. Think of the expectations you face when avatars integrate into your working life. Avatars interacting between two coworkers is one thing, but between the HR department or other organizations is another. Now I’ll have to worry about being mistreated or discriminated against if I don’t choose the proper look.

Lets start by assuming you’ve already installed mhvtl, you have a few virtual tape drives, a media changer, and a bunch of virtual tapes. You can control the media changer or library device at /dev/changer. Using MTX utilities, you can ask the changer to load tapes into drives and list map, etc. But i’ve found it’s actually easier for testing to control the drives directly. You can load and unload tapes directly into and out of a drive by barcode label and tape drive queue.

Use the following steps to get an image of a HP Thin Client running as a virtual machine in VirtualBox. I’m running Fedora 11 and VirtualBox 3.0.0 r49315. The thin client is running a stripped down Debian Etchnhalf (no ‘less’ pager command, man pages?!) And finally, if you log in with root or another user, you’ll get to a full xfce desktop
