Connect to VM without XenCenter

Written by Ingmar Verheij on February 2nd, 2012. Posted in PowerShell, XenServer

Author: Ingmar Verheij

If you want to connect to the console of a virtual machine running on Citrix XenServer you either need XenCenter or the Web Self Service portal.

I created a PowerShell script that connects to the console of the virtual machine, without the use of both. This script can be used to offer a shortcut to a virtual machine without requiring the user to have XenCenter installed, or having a XenServer Enterprise or Platinum license (it works with the free license).

No network on WANem (Citrix XenServer)

WANem is (as the name implies) a WAN emulator that’s available for free and therefor ideal to use in a lab environment. WANem is built on the Knoppix distribution and supplied as a bootable ISO or a virtual appliance. Unfortunately the virtual appliance is only provided for the VMware hypervisor.

I’ve got a lab built on the Citrix XenServer hypervisor and should therefore use the ISO. Installing (or actually booting) WANem is no rocket science, using it is a bit more complex. A guy named José Luis Gómez Ferrer de Couto has written an easy to understand  tutorial  (in Spanish) how to use WANem in Citrix XenServer.

Unfortunately there is a small pitfall on my Citrix XenServer 5.6 machine, the network is unreachable.

HP Proliant DL380G6 unexpected reboot

Written by Ingmar Verheij on July 1st, 2011. Posted in XenServer

HP LogoCitrix XenServer 5.5.0 is installed on a HP Proliant DL380 G6 server. The customer complained that VM’s experienced unexpected shutdowns without finding the cause of the problem.

After spending some time troubleshooting on the virtual machines I couldn’t find the source of the problem. No BSOD on the VM’s, UPS showed no loss of power and there are no scheduled mechanismes that can cause the issue on the specified dates.

Eventually  I found that the cause of the issue is a bad driver as part of the HP Insight Manager Agent.

Do we need ‘fancy’ features for VDI?

Written by Ingmar Verheij on October 30th, 2009. Posted in Desktop Virtualization

Everyone knows that more and more people are thinking about VDI, or at least they’re talking about VDI. And most of these people don’t really know what they’re talking about, what they really want and what they need. There are more usecases, solutions, alternatives which might be better for most of them.
In this article i’m talking about ‘hosted virtual desktops’, the way most people see VDI. The desktop is a virtual machine running on a hypervisor in the datacenter.

Yesterday I attended a presentation where VMware was talking about VMware View, there product for VDI implementations. In this presentation one of the key-features of VMware View was there ESX plaform, and all the ‘fancy’ features this hypervisor has. And with ‘fancy’ features I mean features like VMotion, High Availability, DRS and Fault Tolerance.
These are all great features and very usefull, in enterprise environments, for servers. In smaller environments these features aren’t necessary or even needed. In fact, in most enterprise environments not all features are really required, there used because “we can”.
