virsh - specifying openvz vm sample in domain creation xml

Hello

I need to specify the "vm sample name" in domain creation xml. This is 
the option which is provided to vzctl wtih  --config parameter,  I can 
see that in openvz_driver.c there is below code .....

if ((vmdef->profile && *(vmdef->profile))) {
         ADD_ARG_LIT("--config");
         ADD_ARG_LIT(vmdef->profile);
}

But i am not sure what to put in "domain creation xml" to avail that 
option ? I cant find anything about it in documentation or around google.

Regards

James

It looks really nice. But not an easy fix. I'm
at the moment crossing my fingers and running an
update to pre-release Ubuntu Precise on my test
box... I need to confer with another person before
adding in the backports.org version to get it on
our squeeze based production server. One does not
do such things lightly on production boxes!

call for volunteer: FLOSS weekly podcast opportunity

The FLOSS weekly podcast is interested in doing an interview about
libvirt development on June 6, at 9:30am Los Angeles time (UTC-7).  For
more information on past podcasts, see:

http://twit.tv/show/floss-weekly

With prodding from Justin Clift, I have volunteered to take on the task,
but the show host, Randal, prefers to have two developers per show, so
I'm looking for anyone else who has developed for or with libvirt, who
would be interested in sharing the opportunity.  You don't have to have
a lot of commits under your belt, so much as having enough active
interest in the project and what it enables you to do.  In fact, having
someone not directly tied to Red Hat as the second contact will probably
provide a nicer balance to the interview.

Reality check requested...

Is this going to do what I think it will
do? ie will the output be runable on a
current licensed vmware server?

qemu-img convert -f raw test.img -O vmdk test.vmdk

I don't know, since qemu-img is not maintained by libvirt.  It's worth
asking this on the qemu lists instead.

The disk format should be fine but the VM may not work you didn't say what kind of VM it is - for example is it
KVM/Xen/etc 
VMware uses different emulated hardware and different drivers so your mileage my vary.

This particular test was a linux Ubuntu server built
this weekend via virt-manager. The goal is to be able
to build a disk with the tools I have in linux and
ship it to someone who is running a current licensed
ESX version.

I had the impression that libvirt could handle a vmdk
from a VMware server; but can it go the other way?

it's not about libvirt it's about your hypervisor.
You say virt-manager but that could be kvm, qemu or xen. I'll presume kvm for now.
KVM emulates a different set of hardware components than VMware does - eg. PIIX3 chipset, IDE (or virtio),
ich9 (or maybe ac96/es1379) soundcard, etc
When you take a VM from one platform to another it will see different hardware - eg. it might see SCSI on VMware.
Linux is much better than Windows at adjusting to hardware changes but you have to be careful about how you
configure the guest - eg. use emulation (IDE) rather that paravirt devices (VirtIO) that means you lose
performance but are more likely for the VM to boot on VMware.
