Date: Mon, 7 Nov 2005 09:32:40 +0300 From: Solar Designer <solar@...nwall.com> To: owl-users@...ts.openwall.com Subject: QEMU Hi, I'd like to share the (trivial) recipe for running QEMU on Owl. I'll start with some information on what QEMU is: http://fabrice.bellard.free.fr/qemu/ "QEMU is a generic and open source processor emulator which achieves a good emulation speed by using dynamic translation. QEMU has two operating modes: * Full system emulation. In this mode, QEMU emulates a full system (for example a PC), including a processor and various peripherials. It can be used to launch different Operating Systems without rebooting the PC or to debug system code. ..." To get QEMU to work on Owl, it is sufficient to install the unofficial packages (Fedora rebuilds) available under /pub/Owl/current/unofficial on our FTP mirrors, then additionally install libSDL (the binary package from Fedora Core 3 worked fine for me; to build it from source, one would have to install a few more tools, including nasm). Then QEMU 0.7.2 just works. To boot the Owl live CD image, use: qemu -cdrom Owl-current-20050913-i386.iso -boot d The system boots and works fine (in a window in X, or can be switched to full-screen with Ctrl-Alt-F), including networking (using the emulated RealTek 8029 NIC). Additional "hard drives" (located in sparse files on the host system) may be added with further options. FreeDOS and ReactOS also work fine (although ReactOS is not very reliable yet). I am installing Cygwin in ReactOS at the moment, -- it's very slow, but the installation works so far (download speed is limited to 25 KB/sec by the progress bar updates in the GUI, -- the "qemu" process is at 100% CPU). (I'm not sure if Cygwin itself will work under ReactOS once installed. We'll see. But this is not a QEMU issue.) (Update: ReactOS locked up at 56% of the Cygwin install, in the middle of groff download. I'm not sure why. I don't think QEMU is to blame, more likely it's a ReactOS issue.) -- Alexander Peslyak <solar at openwall.com> GPG key ID: B35D3598 fp: 6429 0D7E F130 C13E C929 6447 73C3 A290 B35D 3598 http://www.openwall.com - bringing security into open computing environments Was I helpful?
