Thanks Vincent!
I guess I should have just looked in the parallel.c file.. Not being too
familiar with linux, I just assumed the port was forwarded to linux, I
didn't realize qemu had to code the transfer of data, and thus could easily
log it. Now that I think about it, that's pretty stupid of
Hi all, I ran successfully Qemu to simulate ARM system on Linux host with the following command: ./qemu-system-arm -kernel zImage.integratorCP -append "root=/dev/nfs nfsroot=192.168.7.1:/mnt/nfsqemu rw ip=192.168.7.2::192.168.7.1:255.255.255.0 " -net nic,vlan=0 -net tap,vlan=0,ifname=tap0,scr
As a follow up to my previous post - I'm debugging data via the host
parallel port to some custom hardware. The OS (which I don't have code for),
sets up the RTC for a very fast 0.25ms (4096Hz) time, and runs exclusively
off the interrupt geneted, ie all subsequent timing and functions are based
Hello Tieu,
Do you think that posting same long mail several times will get you more answers than careful reading of docs/some thought? ;-)

this:

access the cdrom.

Hi all,In Windows, I use ProNFS to create a NFS server on my host; OpenVPN to create a TAP-Win32 Adapter. When I run Qemu to simulate ARM system by the following command:qemu-system-arm -kernel zImage.integrator -initrd arm_root.img -net nic,vlan=0 -net tap,vlan=0,ifname=my-tapAnd after that, in Qe

Hi,
when using a higher resolutions then 640x480 resuming a guest freezes (I
ran into that problem with linux, fbsd and win xp guests).
The monitor still works, but the guest doesnt respond to anything.
Workaround: use -std-vga as argument to qemu (dont emulate cirrus vga
but a standard vga card)
Hi,
although it's not yet released, I tried the qcow2 format on some OSes.
Linux, Windowx XP and OpenBSD worked quite well, but I had a
reproduceable issue with FreeBSD:
qemu segfaults when creating a snapshot. Afterwards the disk is
unuseable (at least qemu hangs when reading it).
I just thought
This is a PCI save/restore issue. I am working on it. In between you can
boot and wait until the VGA is initialized by the guest OS and then do
the loadvm.

- card is not reset, current rx/tx descriptor number is not reset when card is stopped by d

I can confirm this happens under linux also. Never thought to try 24bit.

Hi,

Probably because:

If you did this, I would have thought you were letting the guest alter the state of the disk image,
