Hypervisors and the features discussions, will this become obsolete?

With the upcoming release of Hyper-V 3.0 we see a lot of movement from both VMware and Microsoft on marketing level so all features are promoted, recently this type of marketing became a bit more ugly as VMware launched a ‘Get the facts‘  and older blogs from Microsoft on ‘Windows Server 8: Hyper-V 3.0 Evens the Odds with vSphere‘. Dan Brinkmann posted a very useful overview (from a Microsoft perspective) about the hypervisor on his blog.

Citrix: Setting up Merchandising Server, Task canceled by a user

Today I was setting up a Citrix Merchandising Server. This is the virtual appliance that you can download from MyCitrix and the one I downloaded was the OVA file for vSphere. When I tried to import the OVA file I got an error: Task canceled by a user at 99%. After some research I found the following article: CTX128895.

This contains the following:


When importing .obf files to Merchandising server running on VMWare 4.1.0 ESXi, the user receives the following error message:

“Task was canceled by a user”

The following report is returned when importing:

~~~Deploy OVF templateCitrix Merchandising Server 2.1The task was canceled by a user.Waiting for host <FQDN> (1/1) port data update task to complete<domain name>\<username><FQDN> ~~~


Extract the .obf files with WinRar and import them.

So I downloaded WinRAR, opened the .OVA file and extracted them to a seperate folder on my hard drive. After the extraction I followed the instructions to import the .ovf file from the Citrix eDocs pages.

Remarkable: In these eDocs pages the following is stated “Note: Unzipping and manually importing the .ova file is not supported.” But because the CTX article clearly states differently I just followed the instructions mentioned and in my case it did work.
