I did something different, that will build a raw image directly from a
xenserver export, on the fly.
Compared the resulting file (via MD5) with xenmygrate.py and there is a match.
Currently, this is the faster way to convert a XenServer image to a
raw file. Don't need to wait
for export, tar extra

I think it's even possible to modify that shell script to pipe into
nbdkit and from there to ‘qemu-img convert’. I'm too lazy to actually
do that right now, but the basic idea is here:

You'll probably have to add ‘-m 1’ to the qemu-im

Here's my solution, as a nbdkit plugin written in Perl.
As with Max's solution I don't bother to parse the virtual size out of
the XML file, so you need to specify that on the command line
otherwise the disk will be truncated to the largest extent stored in
the file. Also the ‘.xva’ file must not

Nice, I didn't know qemu-img convert could concat

That's fine to download. Also you could compress it
I'm thinking on how to prove you a sample XVA
I have to create (and populate) a VM because an empty image will result in
an empty XVA
And a VM is 300-400Mb as minimum
