Hi List.
I'm in contact with one of the writers for the german (large) computer
magazine c't (computer and technology) defending qemu (he neglected some
features qemu has in one of his articles). Now he asks me for an article
about what the average user would benefit from when he would use qemu

Qemu can be used without the need to install anything, which is
especially useful if you put a preconfigured OS image plus qemu
binaries (for different host OS') and

Not necessarily. It is true that QEMU offers a load of features that

G'day all,
Been playing with multiple vm's on linux and hacking around my suspend/resume
dropped interrupt issues.
I just noticed the /dev/rtc interface appears to be very single use oriented.
If I run multiple vm's
simultaneously on the same machine, the 1st one picks up the interrupt driven

I must admit I haven't used Virtual PC and have no idea about what it
can do, but I tried VMWare.
In terms of using, apart from the source code, I think the biggest
advantage of QEMU is the amount

Well, in addition to system emulation qemu that I'd guess most users
want qemu for, it has user emulation where you can

Hah, and of course that bit is only found in Xen's qemu-dm. Doh!

With a proper async API, is there any reason why we would want this to be

You're right. This O_SYNC bandaid should

I'll write this here instead of answering to each to keep the noise down :)
Thanks a lot for the good ideas and comments!
I'll simply collect the ideas and leave my cynical comments about lazy readers

QEMU version 0.8.2 is out. You can download it at

Is there a reason there isn't a tag in CVS?

I use both QEMU and VMWare (commercial version),
but for very different reasons. Both are excellent tools that make my job
easier.
I'm primarily a Windows developer, but I do have
some Linux
It seems to me you missed the most important qemu feature. That is qemu will emulate different processors. Just try running an PPC version of Linux on an x86 with VMWARE. To my knowledge the only other programs that can do this are either very expensive or extremely slow.
