[et-mgmt-tools] koan --virt error



Hey guys,

I am trying to use "koan" to provision a xen guest instance but it is
failing and I can't work out why.

I have imported my distros, created my profiles and that side of things
all seems to be fine.

I have cobbler installed on a RHEL4 system and I am trying to create the
guest instance on a CentOS5.0 system. I can create a guest instance
using "virt-install" using the same config that koan uses and it all
works fine.

The output from koan follows:

[root gbw607su1041 ~]# koan -s 221.206.29.50 -x -p CentOS5.0-xen-i386 -V

As you may see, it says that "/tmp/vmlinuz" doesn't exist but I can
confirm that it does by inserting an "os.listdir( '/tmp' )" into the
code.

Any clues?

TIA
