Description of problem: It is not a bug but a request It would be possible to compress in creating qcow2 image (qemu-img convert -c option) But, there was not option like that in virt-v2v Could you add compression option Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
You are using -o local for virt-v2v, I guess?
Yes I'm using -o local -of qcow2
And editing v2v.ml directly now
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).
