Biggest issue is that you have to extract the tarball, then
reconstruct the raw image and then move it
to the new server.

If you have a multi-gigabyte tarball, this operation is very time
consuming (in example, we have some 400GB
VMs)

With my script, the whole operation needs only the transfer time,
becase I'm extracting, converting and moving
to Proxmox in realtime during the download from the xenserver host.
I've moved from many hours (and many, many
gigabyte needed as free space) to about 45 minutes and no space
needed, all is done on the fly in a single pass.

But I'm planning to create a new php-version that directly talks to
proxmox api and xenserver api, reading the OVA.XML
file and creating the new VM on proxmox node, by reconstructing it
automatically (with network interface, disks, etc etc)

Something like:

$ php xen2pve --host my.host --user my.user --password my.password --vm vm.uuid

just to migrate a single vm in a single pass from xen to pve.
