My QNX virtual machine was terminated unexpectedly when the host OS crashed. Since then, QNX starts saying:

    Read-only file system

that I assume due to an inconsistency on the file system (cf: http://askubuntu.com/questions/197459/read-only-file-
system). I've been trying to use QNX equivalent of `fsck` such as chkfsys, chkdosfs or chkqnx6fs but haven't really 
figured out what arguments I should give especially with virtual machine entity. How can I run those commands? Or how 
can I recover the file system?

Thank you.
