yum groupinstall "Desktop" "Desktop Platform" "General Purpose Desktop"

appears to have worked.  As I had already installed two of these I
infer that the missing bit was "Desktop Platform".  Is there a purpose
served by making the process of installing the gnome-desktop so
opaque?  Not that it matters much to me for I am likely to be
switching to kde once Redhat embraces Gnome3.  But it does seem
needlessly convoluted.  I thought that the whole purpose of
groupinstall was to avoid this sort of peek-a-boo package selection.

Anyway, it is installed and working.  This is a temporary arrangement
as I intend to remove the desktop components from the kvm host OS once
I am finished.

There is one 'gotcha' however.  When I installed the three of these
packages NetworkManager got turned on.  This evidently overrode the
NM_CONTROLLED=NO configuration in the ifcfg files.

This is not a good thing when you have eth0 linked to a bridge and you
have a dhcp server somewhere on your lan.  I ended up with br0 having
one IP and eth0 having another, which had, shall we say, interesting
effects on connectivity.

Thank you for the help. I am very much afraid that I would never have
sorted this out on my own.
