The following should do it:

dd if=/dev/hda bs=1024 | gzip | ssh root at host_ip 'gzip -d | dd
of=hda_file.img bs=1024'

hda_file.img will be an image (bit by bit) of the hda disk. You may
then try to use the image with virtualbox (perhaps the raw image or
using  some conversion tool to convert it to a vdi image type, etc).
