Koan virt install hanging
 
Hey,

Happy New Years!

I am having an issue with doing a koan virt install. I am trying to
build a Centos5.1 Xen VM and during the initial boot it hangs at the
same spot every time. I am using Cobbler version 0.6.4-2 and Koan
version 0.6.3-3. Below is the output from the install during the boot
where it hangs. Can some one help direct me on what might be my
problem?

Regards,
Jason Hartley

I think I know what is going on.

It's not hanging, what is happening is that the virtualized console no
longer becomes useful once the VNC graphics mode engages -- in other
words, you should be able to watch the rest of the install with
virt-manager.


Older versions of koan had a flag to disable VNC support, but this was
missing in recent versions (because I was not aware of the virt console
issue). In newer versions of koan (such as the test builds...
http://cobbler.et.redhat.com/download/testing) there is once again a
--nogfx flag.


When this flag is used, the installation will happen entirely in the
virt console (and is watchable in text mode), though you will not be
able to get VNC graphics at the same time.


qemu/KVM (another virtualization type cobbler supports) does not support
the --nogfx flag.


I suspect most folks using VMs in an automated context would want to
disable the VNC/graphics bits so that they could use the text consoles.


Since koan in the "testing" directory does not contain any new features
that require the newer cobbler, I can look at releasing this version
(with the --nogfx flag) in a few weeks to Fedora/EPEL.

Thanks, for the quick response. Your explanation is spot-on. I
played around with virt-install, turning the graphics support on and
off, and I got the same behavior with the graphics on.

Thanks,
Jason Hartley
