I'm guessing CentOS 6.2.
Correct.
The error is right there in the output:
qemu-kvm: -drive file=/VM/Ubuntu-Media/Ubuntu-Media-Copy.vdi,snapshot=on,if=virtio: could not open disk image /VM/Ubuntu-Media/Ubuntu-Media-Copy.vdi: Operation not supported
qemu cannot understand this file. It could well be that VDI support is disabled in CentOS, or the file format is some later variant that qemu doesn't support.
I saw that but assumed there was something else wrong.
There's a newer version of libguestfs in RHEL 6.3, but the basic problem here is with qemu.
According to Red Hat virtualization documentation qemu-img supposedly supports converting vdi images, so qemu should know how to read them at least. Libguestfs is not standalone? So it requires qemu-kvm to load the image before it can mount it? I don't find any reference to whether vdi is officially supported in RHEL 6 or not other than the qemu-img.
