I am trying to install RHEL4 as a guest OS using .hvm configuration. Since the 
istallation needs 4 CDs, how to specify muliple CD-ROM ISOs in the 
configuration? I tried to override the ISO file with next ISO file each time 
it pops up a "change CD" screen. It works only for the first time "change 
CDROM", then it shows error "unable to access CDROM" for the next "change 
CDROM". Any suggestion how to handle this? Thanks.
