[Qemu-devel] how to begin with qemu and networking
Hi, I am documenting about qemu. I want this architecture: http://locataire-serveur.info/workspaces/members/mihamina/public/architecture-qemu/ The host is a Linux Debian amd64. - How could I set the "internal" IP of the host to 10.0.0.1? - Is the emulated guest a 32bit or a 64 like the host?

[Qemu-devel] VLAN inside qemu
Hello, I'm trying to experiment VLAN networking with qemu but the doc doesn't help me at all. I want to setup a LAN composed by qemu host, each guest communicating with each other. It's for testing etherboot. I want to have a host e.g. 172.16.12.1 acting as a DHCP/TFTP/nfs server and several clients (at least 2) connecting with it. What could be the command line to launch these qemu? Is tun/tap unavoidable?

(It is real easy to use dd to convert split images into single images, so support for this is not really needed.)

[Qemu-devel] Experiences with qemu-system-ppc
What are the prospects for qemu-system-ppc being improved to the point where I can do a vanilla install of popular ppc32-linux distros? I've tried a vanilla install of Debian Sarge (3.1). That went smoothly, except for the stage right at the end, where the disk image is made bootable. The resulting disk image is, despite much messing around, not bootable (using QEMU from cvs). Vesselin Peev made a ppc32 Debian Sarge image with a specially modified external kernel to work around this problem (http://free.oszoo.org/ftp/images/debian_sarge_ppc.tar.torrent) and that does work. Unfortunately QEMU consumes 100% host CPU even when the virtual machine is idle, which means it's not useful for a long-running virtual server. And the reliance on a specially modified kernel means normal updating/upgrading of the virtual machine isn't possible. My goal is to run a farm of QEMU virtual ppc32 machines to do overnight builds/tests of Valgrind on different ppc32 distros.

[Qemu-devel] SPARC iommu mapping
Hi!
I still have problems when using a disk image for the SPARC system emulator.
Reading and writing now works better than in previous versions, but sometimes
data written to image is simply corrupt. To find this problem I wrote a small
program writing data to the beginning of a disk image. Afterwards I compared
the written data in the image with the expected values. Most of the data was
correct, but sometimes a few pages mostly contains only zeros.
To find this problem, I enabled debugging in the esp.c file and printed the
mapped address (after iommu mapping). In some cases the mapped address is
zero:
Normal write:
ESP: DMA Direction: r, addr 0x008fd000 000b
ESP: DMA Direction: r, addr 0x0bea1000 e000
ESP: DMA address 0bea2000
ESP: DMA address 0bea4000
ESP: DMA address 0bea5000
ESP: DMA address 0bea6000
ESP: DMA address 0bea7000
ESP: DMA address 0bea8000
ESP: DMA address 0bea9000
ESP: DMA address 0beaa000
ESP: DMA address 0beab000
ESP: DMA address 0beac000
ESP: DMA address 0bead000
ESP: DMA address 0beaf000
ESP: DMA address 0beb
Faulty write:
ESP: DMA Direction: r
ESP: DMA Direction: r, addr 0x008fd000 000b
ESP: DMA Direction: r, addr 0x0beb1000 e000
ESP: DMA address 0beb2000
ESP: DMA address 0beb3000
ESP: DMA address 0beb4000
ESP: DMA address 0beb5000
ESP: DMA address 0beb6000
ESP: DMA address 0beb7000
ESP: DMA address 0beb8000
ESP: DMA address
I used this code in handle_ti to produce this output:
dmaptr = iommu_translate(s->espdmaregs[1] + i);
if ((olddma&0xf000) != (dmaptr&0xf000)) {
DPRINTF("DMA address %08x\n", dmaptr);
olddma=dmaptr;
}
Unfortunately, I'm no hardware or SPARC expert and it took a whole day to
track down this problem. So I'm not able to find the reason for this
behaviour. What may cause the wrong mapping? Is this some kind of page fault,
which must be handled by the kernel? Or just a bug?
regards,
Jörg
