Description Shaolong Hu 2014-03-24 02:30:35 EDT

Description of problem:
-----------------------------
kvm unit test "debug" has a little issue in RHEL7, we plan to add kvm unit test to qemu-kvm test plan, this bug is to track the problem, we are aware the problem may be caused by qemu/kvm/kvm unit test or host running the test, put in qemu-kvm component first, any information/suggestion is appreciated.


Version-Release number of selected component (if applicable):
---------------------------------------------------------------
qemu-kvm-rhev-1.5.3-55.el7.x86_64
3.10.0-101.el7.x86_64
host cpu: Intel Penryn

I think for RHEL7, qemu has no longer much difference from upstream, which in any chance affects kvm unit test, so i use our qemu-kvm "QEMU=/usr/libexec/qemu-kvm ./run_tests.sh" to run the test, but if i am wrong, please correct me.



Steps to Reproduce:
------------------------
1. A typo makes debug test fails to be ran:

--- a/x86/unittests.cfg
+++ b/x86/unittests.cfg
@@ -156,5 +156,5 @@ extra_params = -cpu host,+vmx
 arch = x86_64
 
 [debug]
-file = debug.flag
+file = debug.flat
 arch = x86_64

2. one case fails, and whole test deems as passed, not sure whether a problem:

usr/libexec/qemu-kvm -enable-kvm -device pc-testdev -device isa-debug-exit,iobase=0xf4,iosize=0x4 -display none -serial stdio -device pci-testdev -kernel x86/debug.flat -smp 1 -display none

enabling apic
PASS: #BP
PASS: hw breakpoint
PASS: single step
FAIL: hw watchpoint
Return value from qemu: 1

Comment 8 Paolo Bonzini 2014-07-07 12:18:51 EDT

Ok, reopening then.

Comment 9 Andrew Jones 2014-07-08 05:20:57 EDT

Closing again, upstream already has typo fixed, and the rhel7 tree is still getting sorted-out (so it has been rebased to upstream, and thus has the fix).
