RE: [Qemu-devel] Linux 2.6.15 hangs with QEMU 0.8.0

Turned out that Thiemo's patch labeled "[Qemu-devel] [PATCH 3/8] Mips improvements" did not just clean up the code as its description said, but removed a call to do_raise_exception(EXCP_EXT_INTERRUPT); That made my Linux boot, finally, Sorry for the noise.

Re: [Qemu-devel] block device loopback

I've created a file that I'll call hda.disk like this : "dd if=/dev/zer of= hda.disk count=1 bs=1M seek=1023" and i use it like "qemu -hda hda.disk" The problem i meet is that i can't use this file outside the virtual machine and I'm trying to program a block device driver to read this file as a IDE drive. The aim of this driver is quite similar to the loop driver but instead of "emulating" a partition, it emulates a IDE Hard Drive and give an access to it via /dev/vdX and it's partition via /dev/vdXpY. Perhaps you will wonder why i use the qemu's mailing-list for this problem : - i don't know exactly where i can find a way to achieve this project ; - i wonder how you read your hda.disk without using qemu ; - i would like to know how qemu fix the virtual drive property inside the virtual machine (cylinders, sectors, etc...) ; - i don't know anyone interested by this problem and quite good enough linux driver developer to help me. Thank you very much and have a nice day ! Hi! how many partitions do you have on that virtual disc image? maybe 1 is enough in most cases.. once i've read on a forum the next 'trick': [EMAIL PROTECTED]:~$ /sbin/fdisk $HOME/image/qemu-win98.img You must set cylinders. You can do this from the extra functions menu. Command (m for help): p Disk /home/nyos/image/qemu-win98.img: 0 MB, 0 bytes 128 heads, 63 sectors/track, 0 cylinders Units = cylinders of 8064 * 512 = 4128768 bytes Device Boot Start End Blocks Id System /home/nyos/image/qemu-win98.img1 * 1 520 2096608+ c W95 FAT32 (LBA) Partition 1 has different physical/logical endings: phys=(518, 127, 63) logical=(519, 127, 63) Command (m for help): q so, there are 63 sectors/track, one track is 512 bytes long, and the 1st partition starts at 1th track 63*512*1=32256 so the following command: sudo mount $HOME/image/qemu-win98.img $HOME/win98loop -o loop,offset=32256 -t vfat will mount the 1st partition in that image into the apropriate directory by ignoring the first 32256 bytes of the image leaving only the partition in it.. hope it helps Light thinks it travels faster than anything but it is wrong.

[Qemu-devel] ESP fixed
I got the ESP Set ATN & Stop command working. Linux uses it only for probing disk sizes, but of course if that fails, the zero sized disks will not be very useful. Now all distro installers I tried detected the disks correctly. Some distros didn't detect ESP or Lance automatically when using Proll, but OpenBIOS didn't have this problem. _ Express yourself instantly with MSN Messenger!

Re: [Qemu-devel] qemu-i386 segfaults when running wine on a x86 CPU?
But, I am using a version of wine on Linux compiled for Linux? wine is a Linux program is it not? I got the segfault when I ran qemu-i386 /usr/bin/wine when I run file /usr/bin/wine I get /usr/bin/wine: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.4.1, dynamically linked (uses shared libs), stripped. I should be able to run 32-bit ELF executable compiled for Intel 80386 CPUs with qemu-i386, shouldn't I? Note that, I didn't even try to run a Win32 executable with wine, I just tried to run "wine", it should have printed its command line options/help and exited without doing anything strange...

(The usefulpart is of course that programs compiled for a different CPUarchitecture than the host's can be run.)However, encouraging progress has been made on qemu-darwin-user, which will do what you want to do.
