First of all, let me thank you for the tip on guestfish.  I am a newbie to 
Fedora-virtualization and am not aware of all the packages involves let alone 
all of the functions/packages that could be useful.  It would be nice if there 
was a list somewhere which listed such packages along with a brief description 
of what each did.

The vmware virtual disk file I used was first made into a single file rahter than 
split using vmware-vdiskmager.

OK, I used guestfish to verify that my "raw" image of a virtual disk was good.  
I then realized that part of my problem was that the rescue-mode system on the 
Fedora 9 netinst and the one on the Fedora 11 netinst differed in the order of 
disks (what was sda and what was sdb).  Once I figured that out, things looked 
better.

I deleted the ide disk definition so that only the sda scsi virtual disk 
pointing at my converted file was defined.  I tried booting up ... the kernel 
boots but then cannot find anything.  Well, this guest uses LVM for swap and 
"/".  lets, try something simpler.

I next built a small (minimal install) Fedora 9 vmware guest with sda1, sda2, 
and sda3 as /boot, swap, and "/" respectively..  I took the vmdk file and 
converted it to raw. OK, plug this file into Fedora-virtualization as sda.  
First, boot up with the Fedora 9 netinst ISO image and I am able to "chroot 
/mnt/sysimage" to the system ... looks great.  Try booking ... kernel; loads 
but fails because it cannot find anything such as "/dev/root", "/sys", or 
/selinux".

Any suggestions?

Gene
