XenServer PowerShell: Capture Metrics


Sometimes, I need to capture CPU, RAM and disk metrics on my XenServer hosts.  I've been able to automate this process with PowerShell. Start-XSMetrics This script starts the metric gathering process on a XenServer host. The first block are the parameters. To make this work, I need to create a SSH session to the XenServer...

XenServer PowerShell – New Windows VM from ISO


I tend to build many Windows VMs on XenServer and want a way to automate as much as possible. I want to avoid using Sysprep.  I'm getting a Windows 10 ISO from Microsoft every 6 months (semi-annual release).  If I go with Sysprep, I have to manually create the VM, sysprep it, turn it into...

Let's take a step back and recall our best practice for sizing the RAM on Provisioning Services.  We would typically say allocate 2GB of RAM for each vDisk image the server provides.  This...

I like when new capabilities provides us with the means to monitor because this data gives me reassurance that the feature has an impact instead of me simply believing it does. Let's look at XenServer 7.1... Continue Reading →

Improving Logon Time with PVS Accelerator


The title is correct.  We can improve user logon time by implementing PVS accelerator in XenServer 7.1. This actually makes perfect sense. We already showed that PVS Accelerator drastically improves VM boot times because portions of the master vDisk image are cached locally.  Booting a VM equates to roughly 80% reads and 20% writes.  VMs...
