I am setting up my own dev environment, but in the mean-time I would like to
propose the following:
PROPOSAL
Auto Ejection of All Mounted CDs
PURPOSE
To make application of patches/hotfixes easier in large environments where ISO
images may be mounted to VMs
TARGET COMPONENTS
XE command line, ie:
xe eject-all-isos
XenCenter (API call to eject-all-isos)
OR in our XSxxxxx.upadate package format as a pre-req script.
EXAMPLE CODE
An example is a file I wrote, xe-eject-all-isos (using Bash for simplicity):
#!/bin/bash
echo "CHECKING"
# Get list of VMs from xe vm-list -- specifically UUID
VMLIST=`xe vm-list is-control-domain=false | grep uuid | awk '{print $5}'`
# Loop through list and see if a DVD/CDROM is present
for VMUUID in $VMLIST
do
VMNAME=`xe vm-list uuid=$VMUUID | grep "name-label" | awk '{print $4}'`
ISOMOUNTED=`xe vm-cd-list uuid=$VMUUID | grep "empty" | awk '{print $4}'`
if [ "$ISOMOUNTED" = "false" ] ; then
xe vm-cd-eject uuid=$VMUUID
echo "UNMOUNTED DVD/CD IMAGE FROM $VMNAME"
fi
done
# END
echo "DONE"
