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.
