qemu vs. vmware

Post by welly » Fri Jan 21, 2005 4:04 pm

Hello all,

Trying to improve the performance of reactOS while I'm testing software on it. Do many people run reactOS under vmware? And if so, any thoughts on the execution speed of reactOS compared with QEMU?

Still have had no joy in running reactOS under virtual PC 2004.

Cheers,

Welly

looks like the performance is significantly better in vwmare.

The performance is better in VMWare, but I prefer Qemu because it's free ;)
With ros, Bochs is the slowest of all, but I find it can run some OSes faster than Qemu (MenuetOS)...

I also found vmware the fastest, but must agree with AcetoliNe in that Qemu is free and so I use it.

OH CRAP!! in vmware it starts in 5 seconds and the vmtools graphical
driver literally rocks!!!!!!!

i believe it even starts faster than if i run it on direct hardware o_0

the only problem that is still present is, the graphics - like if you run
task manager and go to performance tab.. the cpu usage is very
unstable and display drawing is again slow..

but the biggest problem you have is the win32k.sys INstability you know..

VMware is nice and easy, but there are some things that can really upset it (Diskeeper and SETI@Home are the 2 I've found). If those are running when you try and run a VM, be prepared for a slow freeze, long wait, and eventuall crashscreen (NO_PAGES_AVAILIBLE). Other then that it's pretty nice and a new major version is coming out soon.

Coming on, coming up, let me help ROS and I'll be able to look @ a life well used.

Well, the normal OS I run can't run VMWare but runs QEMU just fine. It is interesting, QEMU can run under almost any 32-bit version of Windows, even under Windows 95!

ReactOS is (the last time I was able to get a QEMU build) rather sluggish in QEMU but for laughs I loaded Windows 95 inside QEMU and that actually seemed to run at a decent speed.

Ya didn't they stop development on Qemu?
