Description Shaolong Hu 2013-10-14 07:57:38 UTC
Description of problem:
--------------------------
I recently run kvm unit test (using run_tests.sh with default unittests.cfg) with upstream qemu on latest RHEL6.5 host, there are 3 cases get stuck, 2 cases fail.

I am not sure whether this is a kvm bug, or kvm unit test problem, or i run kvm unit test wrong, i only modify run_test.sh and x86_run script a little bit to separate log file for each case, and i use upstream qemu for i was told in RHEL6 testdev device in our internal version may not guarantee to work, so feel free to change the component or close if this is notabug.

BTW, the "-display none" command does not exists, i have to remove it from script or it shows all cases pass but don't run them at all.


Version-Release number of selected component (if applicable):
--------------------------------------------------------------
kernel 2.6.32-421.el6.x86_64
qemu: latest upstream
kvm unit test: latest upstream

host:

vendor_id	: GenuineIntel
cpu family	: 6
model		: 23
model name	: Intel(R) Core(TM)2 Quad CPU    Q9500  @ 2.83GHz


This bug is to track the "tsc_adjust" case, which gets stuck, i have to kill the qemu process, log:


qemu-system-x86_64 -enable-kvm -device testdev,chardev=testlog -chardev file,id=testlog,path=msr.out -serial stdio -kernel x86/tsc_adjust.flat -smp 1
VNC server running on `::1:5900'
enabling apic 
enabling apic

... (more than 1000 "enabling apic")

enabling apic
Return value from qemu: 137
