 Is it possible to expose raw partition from libguestfs (and

I'm not sure what you mean by this.  Do you mean, expose the encrypted
device as a block device on the host?  (ie. guestmount)
 I found it's surprisingly hard to access VeraCrypt partition
inside
 VHD file. 
I'm not sure what VeraCrypt is, but I don't think we have support for
it in libguestfs, which is going to be a problem.  Unless kernel /
cryptsetup knows about it somehow.
