Hello,
this can be the same problem, I found with partitions under my SuSE.
You can see the error, if you would start colinux-debug-daemon before starts colinux (see in debugging.txt).
Please try coLinux version 0.7.3 from snapshots. There have fixed a fault while getting partition sizes. An opened device blocked it self from getting size information. The error was mostly for partitions, and a raice condition how the Linux kernel opens and closed the block device.
