I have a Qemu problem. I already searched the man page.

I have a HD image file (called ReactOS.img) and want a directory (called ros-hd) to be used as second HD.
I envoke:
Code:
qemu-system-x86_64 -L . -m 1024 -hda ReactOS.img -hdb ros-hd

But it expects a file for "-hdb", not a directory.

Any help?

Greetings and thanks in advance
Peter

Any reason why it has to be a directory and not another image file?

I want to try to run Windows programs I download (which don't work with Wine). For example games.
I could create an image file every time I download a program but I would like to avoid that.

Greetings
Peter

If you only need read access you can use a virtual FAT filesystem: https://en.wikibooks.org/wiki/QEMU/Devices/Storage

create a small .vhd file and use it as a second hard drive. but if you want to use ReactOS for running "some games", I think, you are gonna get a lot of adventures. :mrgreen:

Someone's got to test them. PeterX just wants to see what it'll be like.

If it is the contents of the directory that's actually important, try 9pfs. But, guest (ReactOS here, I suppose) needs to support the particular devices that are involved.
