32-bit and 64-bit x86/x64 pre-compiled QEMU 0.8.2 binaries for Solaris
10 / 11 / OpenSolaris

Should run on Sol10-x86 FCS aka 03/05 or higher (has been built under
Solaris 10 03/05 FCS).
More details later, on request.
Will not require LD_LIBRARY_PATH through both -R and -L plus crle (had
been required for 64bit vs. 32bit libgcc to avoid conflicting versions) :


# crle -c /opt/SUNWqemu/var/ld/ld.config

Configuration file [version 4]: /opt/SUNWqemu/var/ld/ld.config
  Default Library Path (ELF):   /opt/SUNWqemu/lib:/usr/sfw/lib:/lib:/usr/lib

Make sure you have
http://www.opensolaris.org/os/project/qemu/downloads/kqemu-osol-1.3.0pre9-v0.2.tar.gz
installed  :-)


New features:
===========* provides qemu-system-i80586 target identifying itself with cpuid of
586 (i.e. for WinNT3.10 guest support)
* improved RAS  (runs on all hosts equal or higher Sol2.10_FCS; no
LD_LIBRARY_PATH trouble; no crashing SiSoft-Sandra inside Win98SE guest;
strongly enhanced sources wich much improved sparc host compatibility)
* IDE-UDMA patch derived from Juergen Keil''s original patch  (Solaris
x86 guests can now be booted with dma enabled, out of the box as default
/ no grub cmd line)
* Improved support for booting the Solaris10/11 amd 64 kernel 
(Attention: still crashes when in combination with the wrapped kqemu
module, but works okay w/out kqemu)
* New sdl lib
* delivered as SVR4 pkgadd package
* /opt/SUNWqemu/bin/$ISAEXEC instead /opt/SUNWqemu/[32|64]


--Martin

Sorry, the new version doesn''t work with kqemu very well.
This affects the old and the new src equally.
The compiler or build env seems to be the problem.

Please continue to use the previous version that can still be obtained
from
http://opensolaris.org/os/project/qemu/downloads/qemu-osol-0.8.2-bin-x86.tar.gz

Sorry for any inconveniences.

Martin,
>>Sorry, the new version doesn''t work with kqemu very well
So kqemu not working in 64 Bit mode is a known bug (or do you talk about another
bug)?

Unfortunately the "old" binaries do not work on snv_49 - the
"new" ones do.

If you compile new binaries - can you please include the patch from Juergen Keil
for the bug in the info command? This bug is really annoying.

I had been wrong in a negative way: The previous binary tar archive
(installing in /opt/SUNWqemu/[32|64]) has pretty much the same problems
with almost all of the tested guests, on all of the tested hosts :-(
(This was my first major contact with kqemu / my first big testing
matrix session, since my primary platform is sparc and kqemu isn''t
available there.)

At least on my 3 current x86 host configurations.

Dammit, I have no time for games like this.
Not currently.


W/out kqemu anything should work as expected.


_-_-Martin

Just so I am clear, the amd64 binary, under an amd64 kernel, does not support
using kqemu? How can I tell if I am using the kqemu accelerator?

You can explicitly disable it via

# qemu  -no-kqemu  <foo>

Otherwise optionally use the qemu-monitor the verify current kqemu status:

i.e.:

(qemu) info kqemu
kqemu support: not compiled
(qemu)

I installed the kqemu kernel module and the new package and I get the following:

QEMU 0.8.2 monitor - type ''help'' for more information
(qemu) info kqemu
kqemu support: not compiled
(qemu)

Are you running the amd64 64 bit kernel?
Which qemu binary are you running?

I get the following when running /opt/SUNWqemu/bin/qemu on a 32bit HOST
kernel (with Win98SE as guest) :

/opt/SUNWqemu/bin/qemu -m 256m -k en-us -localtime
/export/home/c.img__WIN98SE -monitor stdio
QEMU 0.8.2 monitor - type ''help'' for more information
(qemu) info kqemu
kqemu support: enabled for user code
(qemu)


You are probably running the HOST''s 64 bit kernel, but are running a
32bit binary, and kqemu doesn''t work because of that (claiming, support
wasn''t compiled in).
Is that the case?

The current implementation of Fabrice Bellard''s closed src kqemu module
doesn''t yet support 32bit vs. 64bit bit-mixing of isainfo -k versus
bittnes of binary.
But future support may come some day, if I understood that correctly.
See into kqemu-wrapper''s src and README for more information.

To make it clearer:

See the same binaries as adm64 versions in

/opt/SUNWqemu/bin/64 for trying out (experimental) kqemu support on a HOST
running the 64bit kernel.

FYI:

This is what you would get with the totally unstable "-kernel-kqemu"
kernel kqemu support activated:

In the _next_ version, yes.
I just saw the patch.

This does include a new sparc pkg to come next week, but not x86 for now.
A pity that we didn''t talk a few days earlier about this / that I
didn''t
see it myself.

Yes, but that alone is not enough: The binary needs to match the kernel,
that is amd64 in this case.
You would have to use

/opt/SUNWqemu/bin/64/qemu-system-x86_64

NOT

/opt/SUNWqemu/bin/qemu-system-x86_64

See this:


bash-3.00# /opt/SUNWqemu/bin/64/qemu -m 256m -k en-us -localtime
/export/home/c.img__WIN98SE -monitor stdio
