First you need to make sure the host filesytem is ok. In the guest, QNX in your case, you treat it just as a normal
machine, the fact that it`s a virtual machine is irrelevant. First you need to figure out if QNX is using a qnx4 or qnx6
filesytem. You can tell be running the mount command, no argument,. For each partition fount it will show the type.
If it`s a qnx4 filesystem you use chkfsys, if it`s qnx6 use chkqnx6fs ! For the argument read the doc on each ;-) Also
in the case check out the doc to chattr +-snapshot as you might need it.
