So I forgot to answer the last two.

--virt-type (see manpage).   This specifies whether (if being installed 
virtually) the guest should be Xen paravirt ("xenpv") or qemu/KVM 
("qemu").   There is also a new notion of "auto" which means, "see what 
I have installed and if the kernels are appropriate".     If your script 
gets rolled into koan, we'd also add a "vmware" here,  though you can ignore
this for now.   If --virt-type is not specified in Cobbler, it can also 
be overriden on the koan command line.

--virt-path (see manpage).   This is related to the patch Adam Rosenwald 
sent over.   Basically it allows for specifying where the disk image 
file (or paritition) needs to go.
This also might specify a LVM volume group.   Again, syntax on valid 
options is documented in the manpage.   If left blank, koan decides the 
defaults.   If --virt-path doesn't make sense for VMware, you can ignore 
it for now.   It might be something we would want to do later.
