ubuntu - Mount VMWare Disk Images Under Linux

Is it still possible to mount VMWare disk images under Linux?

I found the following two articles, both of them recommend to use kpartx -av diskimage-flat.vmdk. However both the articles are old and, when I try it on my Ubuntu Utopic 14.10, it no longer works any more.

$ sudo kpartx -av MyWin81.vmdk

$ sudo ls /dev/mapper/loop* | wc -l 

ls: cannot access /dev/mapper/loop*: No such file or directory
0

Disclosure: My VMWare disk image IS a flat disk image. Furthermore (before you recommend loop mount), it is a multi-partition disk image, with first partition being Window8 and next two in Linux. It is the next two Linux partitions that I'm more interested to work on.

Can someone confirm please? Thanks.

UPDATE:

vmware-mount looks very promising, but I can't get it working yet:

NB, the 2nd and 3rd command is run directly as root, yet I get "Insufficient permissions to perform this operation"?
