Description Carlos Guidugli 2014-04-05 02:35:21 UTC 
Description of problem:
O Fedora 20 with a recompiled kernel 3.13 the command below did work fine, although the virtual machine often got blue screen when de r9 290 driver was loaded. PCI-Assign was not working well on FC20. With Rawhide 3.14 kernel, pci-assign did work well until I set up vfio to run the command below which generated the segmentation fault.

Comment 12 Cole Robinson 2014-04-08 15:28:45 UTC 
Looks like a vte crash. Carlos, you can work around it by using -display sdl
Comment 13 Egmont Koblinger 2014-04-11 21:51:29 UTC 
Carlos, can you recompile vte-0.36 with the patch from https://bugzilla.gnome.org/show_bug.cgi?id=728051#c3 ? I see a chance that it fixes the problem, but I'm really not sure.

Can you please help me reproduce the problem? I'm using ubuntu trusty, and I'm not familiar with qemu at all. Where do I get BATMAN.img (or any other suitable image file)?
Comment 14 Egmont Koblinger 2014-04-27 16:49:09 UTC 
vte-0.36.1 (already available in Rawhide) should fix it.
Comment 15 Carlos Guidugli 2014-05-22 23:33:26 UTC 
Sorry for the delay in answering. You may close the issue because I migrated my system back to Fedora 20, when the kernel 3.14 was released.

The problem occurred when I explicitly added the GPU to vfio driver. But if I configure the device to use PCI-STUB and configure PCI assign on virt-manager, everything works fine. 

Before starting the VM:
lrwxrwxrwx. 1 root root         0 May 22 09:30 driver -> ../../../../bus/pci/drivers/pci-stub

After starting the VM:
lrwxrwxrwx. 1 root root         0 May 22 20:25 driver -> ../../../../bus/pci/drivers/vfio-pci

I'm still learning about all these so not sure if I did something wrong in the first place by explicitly associating the driver to vfio. 

Thank you for the great support.
Comment 16 Jaroslav Reznik 2015-03-03 15:40:01 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle.
Changing version to '22'.

Comment 17 Fedora End Of Life 2016-07-19 11:18:07 UTC 
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
