Thanks for that. I now feel re-assured!

Yes, I realized that... and seeing as how I want to have Windows as a
guest, I guessed I
wouldn't find a 'tweaked' OS around. Hence I needed 'full
virtualization' (I think). Darned
terminology, every time you move into a new domain of interest :-)

I doubt running it will do that. I certainly need to do some more reading.

seems worth it
but a little out of date?

One Linux is enough for me (bear of tiny brain). I need windows for odd apps,
and am curious about Windows 7, it's getting a good reputation.

Nearly. Long time back I wrote an OS for some dedicated hw, in assembler,
with all its drivers. I'm fairly happy next to the hardware.. .Just
not with the x86
setup and it's VT ideas.

Definately Niels. Tks.
Also found another workaround for the tools/curl problem.

http://forums.fedoraforum.org/showthread.php?t=234928

Workaround:

disable libcurl.so.4 in VMWare, e.g.

mv /usr/lib/vmware/lib/libcurl.so.4 /usr/lib/vmware/lib/libcurl.so.4.DISABLE

P.S. Leave the certs untouched, you can install the vmware tools.


HTH others.
