Currently at openvz.org, the templates are packed as tar.xz. HyperVM does not recognize them.

Can someone dig into this?

I am working on some numbers to present, but I think that xz would be a very bad idea. I would suggest anyone who wants to use one of those templates should decompress it and then gzip it. If multiple people were to rebuild at the same time it would really bog down the host. Again, I will have some numbers shortly.

An Ubuntu template of mine
Size
xz - 169 MB
gz - 256 MB
34% savings in disk space for xz
Time to decompress
xz - 25 s
gz - 9 s
64% davings in cpu time for gz
To avoid CPU usage, I have even wondered whether uncompressed tar files would be a better option as storage is the cheapest thing around.

The contributed templates at openvz.org are now in xz format.
So we have to support it or provide a conversion script from xz to tar.gz
