Hi,
I found the following issue. When I try to use pigz with vzdump/gzip I got the following error:

pigz is installed:
root@ckc-b-p0005:~# pigz --help
Usage: pigz [options] [files ...]
will compress files in place, adding the suffix '.gz'. If no files are
specified, stdin will be compressed to stdout. pigz does what gzip does,
but spreads the work over multiple processors and cores when compressing.
...
As you see the pigz command is in single quotes. This doesn't work. There should be none or backtricks. KVM works.
