[Qemu-devel] QEMU 0.4 release

[Qemu-devel] QEMU 0.4 release

[Fabrice Bellard]

Hi,

The QEMU x86 CPU emulator version 0.4 is available at 
http://bellard.org/qemu. QEMU can now launch an unpatched(*) Linux 
kernel and give correct execution performances by using dynamic 
compilation.

QEMU requires no host kernel patches and no special priviledge in order 
to run a Linux kernel. QEMU simulates a serial console and a NE2000 
network adapter. X11 applications such as xterm have been launched.

QEMU can be used for example for faster kernel testing/debuging and 
virtual hosting.

Enjoy!

Fabrice.

(*) Two bytes must be changed in order to remap the kernel at user 
addresses.

Wow, this is very very cool! Has the hosting been testing on anything
else than x86?

[I made a private reply but it may interest other people!]

Currently vl only supports x86 as host, but nothing would prevent it 
from supporting other hosts provided the host page size is 4 KB. Some 
small patches are needed for precise timer support (rdtsc) and to fix 
endianness issues in the kernel parameters.

this is the Bochs mailing list and QEMU's release announcements are
offtopic here. please could you stop that? it just adds more noise
to the bulk of mail everyone recieves from bochs-developers.

I disagree.  QEMU is potentially quite relevant to the Bochs project,
in much the same way that Plex86 is.  Bochs and QEMU are both GPL'd,
and it has been suggested before that QEMU's code translation layer
could be merged into Bochs to give it a portable dynamic translation
mode.

Actually this is the uml-devel mailing list, and while the announcemant
was interesting, this discussion is offtopic here. So please cut the
cross-post-list.

Thanks.
