XenServer get VM by MAC

Byetzion

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 address"
	exit 1
fi

MAC=$1
# You might want to check MAC correctness here. Enjoy doing it. RegExp, man!

# XenServer is agnostic to case for MAC addresses, so we don't care
VIF_UUID=`xe vif-list MAC=$MAC | grep ^uuid | awk '{print $NF}'`

VM=`xe vif-param-list uuid=$VIF_UUID | grep vm-name-label | awk '{print $NF}'`

echo "MAC $MAC has VM $VM"

XenServer – Setting virtual disks names based on the VM names

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…

Quick and dirty delete old files, with exclude list and support for filenames with spaces

Byetzion

Here’s a little script I’ve written which deletes older than AGE days files, and has an exclude list, just in case. It’s meant to be run by cron on a daily basis: #!/bin/sh # Source of all evil DIR=/ftp # Age of file in days AGE=10 # Exclude list – Use pipe (|) seperated values….

  1. Hi,

    you can try this:

    xe vif-param MAC=$MAC params=all

    It will produce some unneeded data, but still you can find it useful. Or if you don’t need the whole package, you can play with the params option:

    xe vif-param MAC=$MAC params=uuid,vm-name-label

    Regards,

  2. Correction:

    xe vif-list params=vm-name-label,MAC MAC=96:f4:60:b2:f7:f7

    1. Thanks for the heads up. I have checked it on several browsers. It is true that I need to fix something to the right of the screen (but I am a bit lazy here…), but the text seems fine on several browsers I’ve tested, following your comments. Anyhow – thanks!
