If you have a Swift installation, it's quite easy.

1) Snapshot your instance in your VMWare or Virtualbox environment
2) Convert the snapshot to a format that the hypervisor used in your 
OpenStack environment supports (ISO or QCOW2 is easiest for KVM)
3) Upload your converted image into Swift
4) Issue a call to Glance to register your image from Swift:

glance image-create --disk-format=<FORMAT> --container-format=<FORMAT> 

The image will then appear in your tenant's list of images in Horizon or 
glance image-list, and you may use it to launch an instance.

All the best,

p.s. You don't necessarily need to use Swift, either... you could always 
just place your converted image on a web server somewhere and replace 
<SWIFT_URI> with the URI of your image.
