Hi list,
some month ago, I submitted this issue:
http://www.mail-archive.com/[EMAIL PROTECTED]/msg16688.html
Recently, I "solved" the problem, here's how :
The backtrace of the generated core dump showed the following :
Program terminated with signal 11, Segmentation fault.

considering that the SDL initialization lead to a crash, I started
QEMU/KVM with the -nographic flag... and it worked. At this point, I
noticed that :
. Starting QEMU/KVM with the -net nic option (without specifying a model)
+ default SDL output : Segfault
. Starting QEMU/KVM without -net nic + default SDL output : everything's
fine except, obviously, the network
. Starting QEMU/KVM with the net -nic option along with -nographic :
everything's fine except I don't have SDL output (didn't tried VNC)
Then I tried to specifiy a NIC model (model=i82557b) and everything just
worked, this is my fix.
As far as I can tell, the following configuration is buggy (for me at
least) :
. Ubuntu Hardy (8.04), 2.6.24-19-generic
. QEMU/KVM > 61 (till I figured out how to solve this issue, I used KVM >
61 with QEMU/KVM 61)
. Default rtl8139 NIC
. SDL output
Googling showed me only one person that seems to have the same issue under
Debian (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=476469), but on
another machine of mine running Debian Lenny, I never had this problem.
Hope this helps,
regards
