Description of problem:
Up until the change that moved the boot property to the relation between a disk and a VM the boot option could not be set when attaching a disk to VM and depended solely on whether the disk is defined as boot or not.
After this change we can decide whether to attach a disk as bootable or not and in that case if we know that VM already has a disk that is marked as boot this option should be grayed out to begin with.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Create a disk with one bootable disk
2. Attempt to attach another disk from the VM disks subtab -> "Attach"
3. A list of disks will be displayed along with a changeable boot checkboxes for each
The boot checkboxes are changeable
The boot checkboxes should be grayed out
Verified to be fixed on build 220.127.116.11-0.1
oVirt 4.0.0 has been released, closing current release.
