Now it's in sysutils/vmdktool. However, it's not all that simple.

I have downloaded the VM disk from VMware ESXi and the image consists
of two files: myhost-flat.vmdk and myhost.vmdk. The latter is a small
text file containing meta-information about the disk. The former looks
like a RAW disk, at least I can mdconfig it and mount the
partitions.

$ file "myhost-flat.vmdk"
myhost-flat.vmdk: DOS/MBR boot sector; partition 1 : ID=0xee, start-CHS (0x0,0,2), end-CHS (0x3ff,255,63), startsector 1, 20971519 sectors

the problem is that sysutils/vmdktool does not recognize either of
them:

$ vmdktool -i myhost.vmdk
myhost.vmdk: File too small (must be at least 1024 bytes)
$ vmdktool -i myhost-flat.vmdk
myhost-flat.vmdk: Bad VMDK magic (got 8ec031fc, want 564d444b)
$

Probably I don't need any converters at all because the *-flat.vmdk is
already a RAW image.
