[Qemu-devel] Summary of problems with Mandrake 10

[Qemu-devel] Summary of problems with Mandrake 10

[Jean-Michel POURE]

Dear all,

Mandrake 10 final version is available for download from 
http://www.mandrakelinux.com/en/ftp.php3

The installation CD has two boot options:
- alt1: kernel 2.6.3
- alt0: kernel 2.4.25

alt0 always results in "No CDROM device found".

alt1 results in:
- segfault if qemu started in frame buffer mode (no pci)
- segfault of X11 is qemu is started with -pci -cirrusvga. Installation 
continues in text mode.

Today, the only way to install Mandrake 10 is to start qemu in PCI mode with 
Cirrusvga and type alt1.

Maybe it would be nice to debug this Mandrake10 problems and understand the 
underlying causes. Just my 0.01 euro. I really would like to be able to 
install a Mandrake 10 distro under Qemu...

Cheers,
Jean-Michel

[Qemu-devel] Status of user-mode networking for win32

[Elefterios Stamatogiannakis]

  I managed to boot the slax live-cd with user mode networking with host 
win2k.

  It discovers the ne2000 as a RealTek RTL-8029 (found at 0xc000, IRQ 9, 
52:54:00:12:34:56)

  It gets an ip address from dhcp (it gets: 10.0.2.15 from the dhcp 
server:10.0.2.2, gateway:10.0.2.2).

  The problem is that it doesn't seem to connect to the outside world.

  Any idea on what else to check?.

  thanks.

  teris.

[Qemu-devel] Using QEMU-fast

[Sander Nagtegaal]

How to run QEMU in the fast mode? I compiled qemu using ./configure | make | 
make install and when I type qemu-fast my computer doesn't recognize the 
command. Only qemu and qemu-i386 work. How to use qemu-fast? Or how to enable 
it?

I have seen with a packet sniffer that the packet payload was 16 bits
misaligned.

I have tried the workaround here included as a patch and 
Win98+vdeqemu pci works.

I am trying to figure out if this is a correct patch or it is the 
writel/readl call parameter to be wrong. (word sized transfers should be
aligned...)

Re: [Qemu-devel] Status of user-mode networking for win32

[Elefterios Stamatogiannakis]

  Mmmmmm.

  If i understand correctly ne2000 links the guest with the host.

  This connection works for me because i can get a dhcp lease from the 
qemu-slirp throught ne2000.

  I can also ping the dhcp server.

  My problem is with the host -> internet connection from what i can 
understand.

  Qemu doesn't seem to open a "real" socket with the outside world at all.

  Also all the above are using win2k as a host with linux as a guest.

  teris.

Search for "CVS" at QEMU's homepage (http://fabrice.bellard.free.fr/qemu/).

Really? ;-)

Please show us the output of configure, especially line containing the
string "target list".

I have tried the patch also with -user-net and it seems  to work.

Windows 98 has a strange behavior with DHCP.
If it remembers an old lease it tries twice to have the address renewed
and regardless of the NAK or new address from DHCP it sends a ping (ICMP
echo), if nobody answers it picks up the old address.
TO solve this problem from a MS-DOS console window type the following commands

ipconfig /release 1
ipconfig /renew 1

Or you can use the graphical cervisia program.
Go to the "Repository" menu, then "Checkout"

fill the lines : 
Repository :           :ext:anoncvs@savannah.nongnu.org:/cvsroot/qemu
