Edit the vm.cfg file and make the new boot virtual disk the first disk on the list.
12.
Note:
The driver domain device use the following root path /u01/app/
sharedrepo. The boot disk root path is /OVS/Repositories.
The entries in the disk section of the vm.cfg file will look something like the
following:
u'file:/OVS/Repositories/rcrepo/.ACFS/snaps/OL6U7/VirtualMachines/
OL6U7/15f96d92a66c4b808035116ab6348d0d.img,xvda,w',
<<-- original boot/root disk

<<-- original u01 disku'file:/OVS/Repositories/rcrepo/.ACFS/snaps/OL6U7/
VirtualMachines/OL6U7/newboot.img,xvdc,w'
<<-- new boot disk
Move the new boot virtual disk, newboot, to the first disk on the list.
u'file:/OVS/Repositories/rcrepo/.ACFS/snaps/OL6U7/VirtualMachines/OL6U7/
newboot.img,xvda,w'
<<-- new boot disk

<<-original u01 disk
The new boot device (xvdc) becomes the first device (not driver domain) and xvda
is the second domain driver device.
