Description:
================
After each time I run qemu-kvm it crashes


Additional info:
================
Package: extra/qemu-kvm 0.13.0-1
Kernel: aur/kernel26-pae 2.6.35.8-1 Linux uw000459 2.6.35-pae #1 SMP PREEMPT Mon Nov 22 08:49:31 CET 2010 i686 Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz GenuineIntel GNU/Linux (processor family: "Core 2/newer Xeon")

$ modinfo kvm-intel
filename: /lib/modules/2.6.35-pae/kernel/arch/x86/kvm/kvm-intel.ko
license: GPL
author: Qumranet
depends: kvm
vermagic: 2.6.35-pae SMP preempt mod_unload CORE2
parm: bypass_guest_pf:bool
parm: vpid:bool
parm: flexpriority:bool
parm: ept:bool
parm: unrestricted_guest:bool
parm: emulate_invalid_guest_state:bool
parm: ple_gap:int
parm: ple_window:int



Steps to reproduce:
================
qemu-kvm -enable-kvm -usbdevice tablet -vga std -m 1002 -localtime -fda /home/thiemel/bin/myqemu-bootfloppy.img -boot order=ac -smp 2,cores=1 -drive file=/dev/sda,index=0,cache=writeback -nographic -runas thiemel -name WindowsXP -vnc :0 -monitor stdio -cpu <CPUtype>
<CPUtype>: qemu32,kvm32
Other <CPUtype>s (including no "-cpu xx" parameter) are running too slow (like without KVM)

I'll try to recompile aur/kernel26-pae with processor family "Pentium-PRO" and will post if it crashes, too.
This task depends upon

aur/kernel26-pae with processor family "Pentium-PRO" - still SIGSEGV... will try "original" kernel26...

btw - with kernel's processor family "Pentium-PRO" other <CPUtype>s (including no "-cpu xx" parameter) are now running OK (like with KVM)
Comment by Tomas Thiemel (thiemel) - Monday, 29 November 2010, 08:30 GMT
Confirmed - crashes on original kernel, too (core/kernel26 2.6.36.1-3)
Please bugfix...
Thanks

  • Field changed: Category (Packages: Extra → Upstream Bugs)
Please try the latest kvm git snapshot, there are lots of fixes since 0.13 version. If does not work, the report to upstream.
Thanks.

Crashes again. Only when parameter "-vnc :0" added to run on background withous "direct video output". Damn... :-(
Will try to recompile AUR/git package...

status with 0.14.0?
Comment by Tomas Thiemel (thiemel) - Sunday, 27 March 2011, 14:20 GMT
It is now OK, with 0.14.0 - you can close this bug as resolved/fixed.
And now I can uninstall aur/kvm-git :-)
