You are using -o local for virt-v2v, I guess?
Comment 2 kwsk 2015-11-10 01:13:37 UTC 
Yes I'm using -o local -of qcow2
Comment 3 kwsk 2015-11-10 01:46:34 UTC 
And editing v2v.ml directly now
Comment 4 Richard W.M. Jones 2015-11-10 08:41:59 UTC 
It seems reasonable to have a --qcow2-compression option
or something like that.  It would just add the -c option
to the qemu-img convert command.

It seems as if it would work with all output modes too,
although it is possible that -o glance and -o rhev do a
reconversion step (not in v2v).
