      OK so this has been bugging me for some time, and its how Xen manages orphaned vDisks.

      Specifically why does it create and leave these 0 GB disks on the system with no association to a VM?

      Also, remember it is XenServer and not Xen server, those mean two different things. I'm assuming you mean Citrix XenServer here?

      NFSv4 is only for security, typically you want to avoid this in a production virtualization environment. You would want to be on NFSv3 for performance reasons.

      @scottalanmiller said in Qubes OS - Using Xen to Secure Linux:

      I think that you have the wrong tool for the job. Others are correct, you just want a normal KVM install. Qubes is the wrong tool here.

      So would this be something like OpenStack or CloudStack? Or are those just a management/obfuscation layer?

      No, MaaS is designed to help OpenStack specifically (but you can use anywhere. OpenStack is the cloud layer. This is a hardware management layer that makes tons of sense in a cloud scenario. It could be used without cloud, like for a computer cluster (Hadoop maybe) but would be uncommon. And you normally use cloud without MaaS. But it works really well for clouds to make them less effort to manage at the hardware level.

      Not very exciting updates, but I suppose that that makes sense in the hypevisor these days. What exactly would we be looking for?

      How come they don't fail over the VMs to another server, then update the original server move them back and so on as to make it an update with no down time?

      Cloud is not high availability. That's a very common misconception. Cloud is beneath the HA layer. Anyone who had HA stayed up and running, of course, but cloud itself is not HA.

      They easily could have chosen to do so, but the workload would not offset the cost I am sure.

      Not really, because you can only do so much HA at that layer. Not every workload can be made HA in that way. But more importantly, HA is always an option and most importantly, HA is something you do, not something that you buy. But anyone who had an outage, like us, chose to not pay for HA because it is cheaper to have blips than to have the cost of HA.

      It's really the end users who opted out of HA.
