Time to betray some serious virtualization ignorance; when do people use QEMU outside a datacenter (presumably for mapping multiple virtual machines to one physical machine)? How often does one need to run binaries compiled for another machine architecture? And setting aside banal scenarios like running Word on Windows inside Linux, when is a guest OS useful?

Re: QEMU 1.0 released
#12Yet another Bellard production (originally, anyway). Let's list a few things he has done: - QEMU: code from which has been used in Xen and KVM amongst others ( http://en.wikipedia.org/wiki/QEMU#Integration_in_other_virtu... ) - FFMpeg, which almost every free video tool uses in some form - The fastest known formula for calculating Pi - The x86 Javascript emulator That doesn't include things like his self-compiling C…
You can include TCC without fear i guess, small and fast C compiler based on the self compiling C compiler you were talking about.

The Android SDK is based on QEMU. This is what lets you develop and test ARM binaries for Android on your x86 PC.
There are many examples of embedded development environments like this.

#14Since the page seems to be down/loading slowly for me, here's the changelog: General - i386-softmmu is no longer named qemu but instead referred to as qemu-system-i386 for better consistency with other targets. A new tool is likely to be introduced that uses the qemu name so distributions are advised to not undo this change. - QEMU now uses a separate thread for VCPU execution. This merges the biggest difference betw…

I use VMs to test for bugs in my code on other platforms, and to test new releases of various Linux distributions.

Fabrice Bellard is an extraordinary human. I know about his work since 1990 when he wrote the LZEXE self-unpacking executable utility for DOS.

Let's say you have a hard drive with DOS and Stacker and you need to copy files from it.
Or you have a disk image and need to copy files from that, and for some reason you can't mount it (Windows or virtualized linux without loopback block devices)
qemu does wonders to disk images.

#18Thought I share this nugget: http://russell.ballestrini.net/virt-back-a-python-libvirt-ba...
Its a python application I wrote to backup guests using libvirt api.
Opensource and public domain.

#19Can I use QEMU to run Mac OSX on my Linux box (at decent speed)?

I run KVM quite regularly on my laptop. I use it to test the results of Linux kernel hacking, to test bootable Linux images of various types (installers, live images, demos), and to test BITS (http://biosbits.org/) without having to run it on dedicated hardware (at least, the bits that don't specifically test that dedicated hardware).
