My advice to you is that you change the file system on drive that holds the 
VMs files from NTFS to EXT2.

NTFS file systems on FreeBSD or even Linux are OK only for doing small r/w 
stuff. I use the ntfs-3g which is really good but don't trust NTFS for heavy 
usage under those OSs. Sometimes it's not even trustable under windows itself.

EXT on the other hand, is very stable in FreeBSD and has very good drivers for 
any version of 32/64 windows (Ext2IFS_1_11a) so you can access you vdi files.

hope this helps.
