The following procedure was tested by me, and was found to be working. The version of the XenServer I am using in this particular case is 6.1, however, I belive that this method is generic enough so that it could work for every version of XS, assuming you’re using iSCSI and LVM (aka – not…
It is an amazing news to me. I really love XenServer. I think that Citrix were able to make a good use of Linux mechanisms for the purposes of virtualization, without abusing the OS layer (like some of the other virtualization solutions did). The file locations are decent (for example – most parts are located…
In this part I will discuss a possible solution to a problem I encountered several times already – failure to understand XenServer use of LVM, but first – a little explanation of the topic. XenServer makes extensive use of LVM technology in order to support the storage requirements of virtual disks. It is being utilized…
One of the worst things you can have in XenServer, is some wize-guy performing a ‘forget storage’ on a storage device still holding virtual disks related to VMs. As XenServer database is internal (for the whole pool) and not per-VM, all references to this virtual disks disappear, and you remain with bunch of VMs without…
I have had a single node of a pool using a different license server. Temporary, unfortunately. It has expired, and as the purchase process was somewhat prolonged, I have had to extend it. I did not want to disconnect my other-four-hosts-pool from the permanent license server, which works so fine for the last year or…
Using the GUI, it could be somewhat complex identifying a VM based on its MAC address. There are several solutions on the network using PowerShell, but I will demonstrate it using a simple bash script, below. Save, make executable, and run. Enjoy #!/bin/bash if [ -z “$1” ] then echo “Requires parameter – MAC…
