Hi,
the qemu documentation states about sparc emulation: "... Please note
that currently NetBSD, OpenBSD or Solaris kernels don't work."
What's needed to get Solaris to word? Or any of the BSDs?

Is there anything that's cycle accurate at all?

Hi,
I get this error, when I don't give qemu a 'hda':
A disk image must be given for 'hda' when booting a Linux kernel.
Why is that? Isn't it completely legal to start without a IDE drive? For
example with:
qemu \
-kernel linux-test/bzImage-2.6.18 \
-append "root=/dev/nfs nfsroot=172.20.

Hm... you have to elaborate on that one. Aren't those caches like other

Agreed. So let's see what's needed to get a reliably corresponding

Hello qemu developers,
I've been unable to find information about date and time in qemu. Two
questions the simpler one:
Can I set the date and time of the system clock at start of the
emulation (or in the manager console)? I've seen a patch [1], but that
doesn't seem to be included in my bui
