Ok, the field is now editable but when add a new disk and enter:
Type: Image File
Disk type: IDE CD-ROM
Target device: /dev/hdd (unused)
Source file: /etc/blah.iso
Driver name: qemu
And apply i get: Failed to define domain from /etc/libvirt/qemu/debtest.xml.new
Error: Unknown failure.
When I then select the new disk in the left frame under VMs (KVM, Xen)
it is detected as /dev/hdc (The first CD-ROM drive) so I guess a

I created a VM using LCMC, the domain name is listed under VMs (KVM, Xen).
When I click disconnect i go to the LCMC 'home' screen again, now when
i click the same cluster again to re-connect the virtual domain under
VMs (KVM, Xen) is gone.

Ok, i tried to add a tablet device which worked. But I could not
remove the mouse device (it keeps re-appearing).
I stopped the VM
Added the tablet
Clicked on remove device for the mouse. (It got removed on the left
frame under VMs (KVM, Xen), but remains on the right frame where i
clicked remove device)
Start the VM again
The mouse re-appears on the left frame under VMs (KVM, Xen)!
PS. I have the same problem when removing disks.
Btw, is there a way to add/remove hardware while the VM is running? I
now shutdown the VM to add/remove hardware.
Another question, is there a way to easily add the created VM using
LCMC to the CRM/pacemaker config?
So after creation click a button like "make highly available" so that
LCMC creates a VirtualDomain primitive resource for it?
