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. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

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.
