Any and all can do that.
Just point it at using a device name instead of the file path.
Xen, KVM, VirtualBox, VMWare ...
They just use it for backing storage, and internally convert the file based images to block devices anyway.
I guess probably not the same efficient. As far as I know if the hard disk of the guest os is an image file on the host OS, the host OS treats it as a file and offer to cache it in the main memory. However if vmplayer access a partition or harddisk it is not cached by the host OS's file system. That might make it even slower. Unless of course the database is in particular on a raw device that is directly accessed from the guest OS, as Sandy pointed out. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
