If c:\ has less than 50 MB free it will refuse to convert it. Use 'virt-df' to check. That said I would be surprised if the 'cp' succeeded but v2v crashed suddenly because of insufficient space.

The partition I'm trying to convert is 50Go large, filled up with something like 40Go. Even with a big error margin, it seems comfortable. Before the P2V, I did no fsck, but I used to microsoft defrag tool (the old 2003 one). I'm not sure it also checks the filesystem integrity... - Finally, when you write about the "NEW" v2v, what version do you speak about? Is the one I used (0.9.1.2) not new enough? (I know it is not the very last, but quite decent though). Well, thank you for having answered. On this conversion, I have no choice but succeed. I also tried the old livecd+netcat+dd option, but the OS did not even boot, even if I copied the MBR and double check the special flag with an hex editor ("FF"). So I will keep trying until success. -- Nicolas Ecarnot
