Prerequisites
Adding a CD to a running VM is not a difficult task if you know which commands to use. By adding I mean we're going to insert a virtual CD disk into a virtual machine using our little virtual hands. ;-)
1. Get the name of your Virtual Machine
In this case the name is CentOS6 and the UUID is cefb9f88-0424-6701-5ba1-070490c69203.
[ root@cloud2 ~/bin ] xe vm-list
uuid ( RO) : cefb9f88-0424-6701-5ba1-070490c69203
name-label ( RW): CentOS6
power-state ( RO): running
2. Get the name of the CD disk
In this case our disk is named CentOS-6.3-x86_64-LiveCD.iso.
[ root@cloud2 ~/bin ] xe cd-list
uuid ( RO) : 0549c68a-e38d-4cd8-9974-ba0b9167ff5a
name-label ( RW): CentOS-6.3-x86_64-LiveCD.iso
3. Identify a free Virtual Block Device number
Use the VM UUID that we retrieved in step 1.
[ root@cloud2 ~/bin ] xe vm-param-get uuid=cefb9f88-0424-6701-5ba1-070490c69203 \
param-name=allowed-VBD-devices 5; 6; 7; 8; 9; 10; 11; 12; 13; 14; 15
4. Add the CD to the VM. Use the VM UUID from step 1, the CD name from step 2 and the VBD device number from step 3.
[ root@cloud2 ~/bin ] xe vm-cd-add uuid=cefb9f88-0424-6701-5ba1-070490c69203 \
device=5 cd-name=CentOS-6.3-x86_64-LiveCD.iso
5. Verify using xe vm-cd-list
By using xe vm-cd-list we can list the CD's currently plugged into our VM.
[ root@cloud2 ~/bin ] xe vm-cd-list uuid=cefb9f88-0424-6701-5ba1-070490c69203
CD 0 VBD:
uuid ( RO) : 40f6b5c9-14fd-4379-d82c-d0ff34472a04
vm-name-label ( RO): 955300270
empty ( RO): false
userdevice ( RW): 5
CD 0 VDI:
uuid ( RO) : 0549c68a-e38d-4cd8-9974-ba0b9167ff5a
name-label ( RW): CentOS-6.3-x86_64-LiveCD.iso
sr-name-label ( RO): NFS ISO
virtual-size ( RO): 725614592
6. Unplugging the CD disk
When done with the CD you can unplug it even easier. We specify the VM UUID and tell it to eject the CD which it does.
[ root@cloud2 ~/bin ] xe vm-cd-eject uuid=cefb9f88-0424-6701-5ba1-070490c69203
