Hello all,
I've trying to implement thread support for user-space Qemu, similarly
to what David has posted in a previous e-mail.
I understand that it is probably not possible to fully support threads
between very different architectures, but i am only interested on
getting x86 on x86 linux emulati
re it should work under all circumstances. It also works
when USE_CODE_COPY is not defined.

Hi guys,

I thought the best way to overcome the restriction imposed in tun/tap
interfaces is to set qemu as suid, and revoke privileges as soon as
the network interfaces are configured, and before any virtual block
devices are opened.
I wrote this little patch, which hopefully does just that.

Hello all,
I have recently installed the latest linux kernel, and i have been
having problems with the tap interface since.
I have been getting the following cryptic message:
warning: could not configure /dev/net/tun: no virtual network emulation
Could not initialize device 'tap'
The tun driver
r the code to be translated (guest code) is actually written to
guest memory before being translated? If the code is simply picked up
from the disk and translated, it would explain why this is the case.

Hello,
I have been in the process of porting Argos to Qemu 0.8.2.
In case you haven't heard of Argos, it's basically Qemu extended to
track network data entering the emulator to identify their illegal use
(exploits, etc).
I am using the softmmu to track all accesses to physical memory to
track wh
Actually, i have also noticed this.
It implies that an exploit might not succeed (this usually the case
with most exploits), since the attacker supplied shellcode will not be

My question is, does anybody know why this happens? Why this

I had a similar problem, but only when not using kqemu.
When using a stack overflow exploit, the shellcode provided only
executes when using kqemu. I can attribute this to either the

Does the copying of instructions occur in user-space or kernel-space?
I would like to port Argos to use the kernel accelerator, but i'm
unsure this is possible considering the accelerator is not open

I've been hacking Qemu for Argos, and i was wondering whether it is
possible to execute code from a virtual peripherals memory.
To be more explicit, i have coded a virtual peripheral that does
nothing, but register some physical memory for memory io. This

I was wondering whether anyone has experience with installing Qemu on
a dual-processor host?
Reading about the problems some of you had with hyper-threading, i
wonder if things become worse on multi-processor hosts?

Hi,
I've started looking at the source code to figure the best way to
write the extension, and I figures out it is best to write it as a new
target CPU based on the i386.
I'm adding some instrumentation code in op.c, which should make things
a bit slower but hopefully not too slow.
There are two

Hello,
I'm writing concerning a possible use for qemu in a project related to
network security.
I'm looking for an emulator where I could load an entire (recent) OS,
like Linux 2.6 or Windows XP and run multiple, potentially CPU
intensive, services (
