Cannot mount any files on debian VPS, virtualization restrictions?

I can't mount any files on my VPS

Code:

$ mkdir 1
$ mkdir 2
$ sudo mount --bind 1 2
mount: permission denied

Thing is, due to the virtualization technology, I'm forbidden from doing anything to the kernel ( I can't load modules, etc ). I'm wondering if that would also stop me mounting things. ( This would make sense as far as mounting external media goes, but since I'm only trying to mount things which are already in the file system, well, dash it all I rather thought I could you know! )

Well if you're not crossing a partition boundary, just use a hard link, or explain what you're actually trying to accomplish and we can tell you a work around.

My program needs to bind sockets, but I want to run it in a chroot. In a chroot, I need /dev to bind the socket. Which must be mounted.

The work around is to bind the socket outside the chroot, and then call chroot from the program code - this is what I'm intending to do, once my x86 development box is working again ( the screen broke
