Welcome to our new home!

It’s taken some time to move the site, especially the moving of the DNS.
SVN and TRAC where moved entirely… unfortunately we missed a post and some comments.
But now we are back up! There will be some graphical tweaks, but the technical foundation is standing.

download Q-0.9.1d104


Special txs go to andreasf for helping patching and porting things to Leopard and QEMU 0.9.1.

Sparc emulation is unfortunaltely still not running on intel. But as soon as we have tracked down these issues, we hope to provide you a stable 0.9.1. So please test and let us know, if You find any bugs.
As You do report, bear in mind, that all interface changes and new features requests should go right to Q2 Milestone. This Milestone is only providing bugfixes and QEMU 0.9.1.

QEMU 0.9.1

mike Q Read on

QEMU 0.9.1 was released some days ago. This means work for us :).
Thank You for all the imput. OS 9 compatibility was asked several times, I’ll look into that.

But meanwhile we are about to patch QEMU to fit into Q.

Andreas F has sent us some patches, which we apply soon.

I, myself have continued with the rewrite of Q, which now works with QEMU 0.9.1. Lots of functionality is already in. Right now I’m working on qControl to add some more comfort. So stay tuned for the checkin and the first 0.9.1 nightlies! Heres a little sneakpeek of Q2 running 0.9.1:

Q rewrite

mike Q Read on

Finally I did take the task of rewriting Q. There are some issues with the current app, that can’t be mended if we stay with the current architecture. The problems are mainly interface related.

If you are interested in what’s going on… have a look at my .plan file in the wiki section. Once I come up with a usable solution, I’ll put a download link on the frontpage.

This is also the moment to come up with ideas of yours… if you think Q is missing something, drop a line.


Finally: Q is going 0.9.0!

mike Q Read on

After heaps of improvement on qemu, heaps of improvement on Q and literally months of testing, we present you: Q-0.9.0.

The Changelog since Q-0.8.2 is epic.

Let me just hilite some of the major changes:

  • flashdrive: import/export Guests as executable pakages… send a guest-pc to a friend - he needs no programm installed to run it (cordney*)
  • Quartz support with faster selective drawing code: faster video output, as no unneeded screenregions are updated (mike)
  • toolbar in fullscreen: have handy functions ready with “cmd-b” (cordney*)
  • network and firewall settings tabs: routing ports was never easier (cordney*)
  • German, French and Polish translation (Katios, Krzysztof)
  • new icons: we now have micro-, fullscreen- and toolbaricons (andy)
  • animated windowcycling: change between fullscreen guests as you would expect ;) (mike)
  • bootorder that supports multiple bootdrives
  • tons of bugfixes

Now: go and enjoy!
