How to kill a hung VM on XenServer


Sometimes you run into a hung VM on XenServer. This is how to kill the VM running on XenServer :


First look up the UUID (in my case 50fa073a- etc)


Using the command list_domains you can find the id’s (0, 6, 7, 9 etc)


Now use the grep command to find the domain ID you need and use the following command to kill the VM : /opt/xensource/debug/xenops destroy_domain –domid <domainid>



Identify memory modules used on XenServer


Today a customer requested to upgrade the amount of memory on their XenServers. This is how you easily can determine which memory modules are being used.

Ofcourse you can use ILO, but then you only see the size and location but not the specific type of (memory) module :


This is how you can identify the specific type :


In the above screendump you can see it’s a dual rank module.


Review Xackup XenServer backup software Part 2


After my review of Xackup XenServer backup software I received serveral emails and tweets with people asking me if I had ever done a restore test. The answer is : ….. YES! Ofcourse. :-)


I did several migrations and restores for testing purposes and they all succeedeed. I advise to install the software on a separate server because it has some impact on the CPU.

Anymore questions? Please leave a comment. :-)


Review Xackup XenServer backup software


The last couple of days I ran into some problems with restoring VM’s on Xenserver. I started looking for Hypervisor backup software for Xenserver. I took a deep dive into the wonderful world called the Internet and found Xackup from Fungusware. Alright, strange name but let’s take a look at the product itself.

I downloaded the software, requested a trial key and after 5 minutes I was ready to go! Installing the software was as easy as hitting next a couple of times and entering the license (trial key). No uploading appliances, no proxy IP addresses or something like that. Let’s take a look at the main interface :


I created a new backup job, look at the pictures below :


Select the VM you wish to backup:


Use a snapshot to create a backup or use NFS/CIFS volume directly :


Specify location, compression, differential etc :



Pre- and post jobs :



Schedule the backup job :


Send email on completion :



And here we go : :-)


You can also use this program to migrate VM’s hot or cold to a new XenServer. Using the steps (source and destination XenServer).

The cost of this al :


85 AUD is approx 55 EUR. You can select as many Xenserver servers as you would like. No per Xenserver limit. :-)

How to : Request (or renew) SSL certificate for Webinterface


This is how you request and install (+bind) a SSL certificate for example Citrix Webinterface.

Before you start you must now the external DNS name of your webinterface. In this case I use
Test to make sure the webserver is responding and the firewall is configured. You notice a SSL warning/error. Something like this :


(The following screendump is a Firefox warning in Dutch Glimlach)

Now go to your Webinterface server and open IIS manager :



Go to the servername in the left pane, select Server Certificates in the middle pane and…

portal003 Create Certificate Request in the right pane.

Fill in the following screens :



Make sure the common name equals the name of your Webserver (Webinterface) on the Internet, for example (For security reasons I greyed out some of the information in the screendumps)



Make sure you select at least 2048 bits. None of the SSL providers don’t accept anything less.


Provide a name for the certificate request file. In this file you will find the CSR. You will have to give this to your SSL provider. When you have done that, you can complete your Certificate Request in the same screen, only one option lower :



Unzip the file you received from your SSL provider and select next :


(Make sure that your friendly name is spelled correctly)

After this step your new certificate is imported :


Now you have to bind this certificate to the right port :portal011

Go to the default website, select SSL settings and choose in the right pane the option bind. Select port 443 and your newly imported certificate. Now stop/start your (web) services and you are ready to go :

All the standard solutions, like internet explorer intranet zones etc. didn’t work.

After some troubleshooting I found out the following group policy setting fixed my issue :

After installing Roll Up Pack 1 for XenApp 6.5 a customer of mine ran into the problem that the 2 services mentioned wouldn’t start. The mfcom service was hanging in a starting fase and the IMA service reported several errors.

I found many many people on the internet with the same problem and I would like to share with you what the solution was that fixed my problem Smile

Fixing ProductFeature error

I wanted to remove the server from the farm and after a reboot tried to join the domain. After removing from the domain and rebooting, I was unable to join the server because of the following error :


I also received some errors about licenses etc. I found out that ProductFeature registry key was empty. HKEY\LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix and check out ProductFeauture option. In my case it’s the Advanced feature edition, so I had to use the ADV option. Other options are :

  • STD (Standard Edition)
  • ADV (Advanced Edition)
  • ENT (Enterprise Edition)
  • PLT (Platinum Edition)

After a reboot there were no more licensing problems and I was able to remove/join the server to the domain :



Fixing DSN files

I checked the DSN files (C:\program Files (X86)\Citrix\Independent Management\Independent Management Architecture). Check out the contents (with Notepad) of the dsn files.

It should look something like this :


ODBC] DRIVER=Microsoft Access Driver (*.mdb)
FIL=MS Access
DBQ=C:\Program Files (x86)\Citrix\Independent Management Architecture\Imalhc.mdb


In my case the WSID entry was missing (make sure you edit it with the name of your server)

After saving the file, execute the following commands :

  • dsmaint recreatelhc
  • dsmaint recreaterade

Reboot the server

Settings security (DSMAINT)

In case the problem still persists, you could try the following command :

  • dsmaint /config user:<user> paswd:<password>

After rebooting I was able to start both services. Both services are using the Network service account
