A 7z archive Compress knows to deal with starts with the six bytes 37 7A BC AF 27 1C - the first two bytes are "7z" - and your archive doesn't seem to do so. The 7z utility supports a lot of formats beyond 7z, maybe it does support vmdks directly? If the vmdk format is https://www.vmware.com/support/developer/vddk/vmdk_50_technote.pdf or something similar then Commons VFS would look like a more natural place for support than Compress IMHO.
