qemu-kvm aborts - glibc "stack smashing detected"
Last modified: 2010-02-21 17:53:45 EST
abrt detected a crash.
How to reproduce
qemu-system-x86_64 -usb -usbdevice tablet -vga vmware -soundhw es1370 -m 1024 -cdrom soas04.iso
Process was terminated by signal 6
Created attachment 367225 [details]
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.
More information and reason for this action is here:
Thanks for the report Bernie
It looks like stack corruption:
#3 0x00000033058faae7 in __fortify_fail (
msg=0x3305941006 "stack smashing detected") at fortify_fail.c:32
Can you reproduce still? How about without '-vga vmware' or '-soundhw es1370'? Or with '-vnc :0' instead of using SDL?
Are you deliberately running qemu-system-x86_64 rather than qemu-kvm?
You have a custom kernel installed? I'm guess that has nothing to do with it, but if you could reproduce without it that would help
Also, note that we recommend people use e.g. libvirt and virt-viewer rather than running qemu directly.

I can still riproduce with qemu-system-x86-0.11.0-12.fc13.x86_64
"-vnc :0" worked without crashing (with or without a vnc client connected).

I tried to exclude other factors by using software emulation. qemu-kvm also crashes.

Now I do have a custom kernel, but I could reproduce the bug also with the stock kernel.

Graphics acceleration does not seem to be possible with libvirt & virt-viewer.
Any updates on this with the latest qemu from virt-preview? https://fedoraproject.org/wiki/Virtualization_Preview_Repository has details for updating to the virt-preview packages.
Both -vga cirrus and -vga vmware work nicely in qemu-kvm 0.12.2, thanks!
