[virt-tools-list] Question regarding "No OS found" when trying to boot VM's

Hi Inverge:

I have the same problem.
Have had it for a while.
If your problem is the same as mine, I'll define it for you.

You are on your machine, running KVM, which you're using to create a VM.
At some time, the other KVM -- Keyboard, Video, Mouse -- has to switch 
from 'your machine/KVM-QEMU to your 'VM' so you can answer the set-up 
questions as when you set up any machine. Since the switch was never 
made, and you never interacted with the build, the VM is built with no 
software, it's got everything else: your processors of choice, memory, etc..

I run KVM (create) time and time again, using every sourcing I can (i.e, 
sometimes loading the .iso, sometimes trying to use the DVD, etc. etc.), 
and one time in a 100, it makes the switch. It's now been years since 
I've been able to make a new VM.

I gave up, after doing all suggested to no avail.

Every now again, the CentOS update lists losts of KVM/QEMU updates, so I 
try it again, hoping the problems has been found by my betters and 
fixed. Still to no avail.

If my described problem is the same as yours, I wish you the best.

Maybe you'll be able to give the Powers That Be the information they 
need to fix this -- I evidently was not.
