Qemu: Want to mount a directory as HD

Post by PeterX »

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: Select all

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.

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:
ANT - NT-like OS for x64 and arm64.
efify - UEFI for a couple of boards (mips and arm). suspended due to lost of all the target park boards (russians destroyed our town).

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.
