[Xen-users] Can't get a CentOS pv working on NetBSD dom0

[Rob G <rob@xxxxxxxx>]

I've been working with this for several, several weeks now.  I'm finding 
it fairly impossible to get a Linux (CentOS specifically is my test 
case) domu running as a pv, under a NetBSD dom0.
I'm running xen 3.3.2

I've tried several different kernels for CentOS.  When using the Generic 
CentOS kernel, I get:
# xm create -c Rob1CentOSpv
/usr/pkg/lib/python2.6/site-packages/xen/util/acmpolicy.py:20: 
DeprecationWarning: the sha module is deprecated; use the hashlib module 
instead
  import sha
Using config file "./Rob1CentOSpv".
Error: (2, 'Invalid kernel', 'xc_dom_parse_elf_kernel: ELF image has no 
shstrtab\n')
Ok, .. The tutorial on CentOS's site claims to use the xen kernel/initrd 
images from their FTP.. here is the results:
--

# xm create -c Rob1CentOSpv
/usr/pkg/lib/python2.6/site-packages/xen/util/acmpolicy.py:20: 
DeprecationWarning: the sha module is deprecated; use the hashlib module 
instead
  import sha
Using config file "./Rob1CentOSpv".
# Error: Device 0 (vif) could not be connected. Hotplug scripts not working.

--

The kernels installed via the CentOS kernels-xen package, the same 
result as above occurs.
I'm just quite confused, there is a large amount of resource out there, 
but not many let you know what specific Xen version such applies to, 
etc.  I'm pretty much stuck with 3.3.2 for now with NetBSD and I'm fine 
with it.
I just don't know what kernel I should be using, and what method(s) I 
should be using to start it.
Here is my cfg file, the kickstart file mentioned is the same one in the 
CentOS pv tutorial: (http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU)
