ABAT Testing report, kernel 3415130f97.., userspace 5b16d32e..

[Zhao, Yunfeng]

Hi, all,

This is today's ABAT testing result against kvm.git 3415130f97a18f354853cab694d392553aa51af8 and kvm-userspace.git 5b16d32e3785274310e9e1970f4221b4966c5474.

Two old issues have been fixed. 
================================================
1. 64bit host crashed when boot SMP linux guest
https://sourceforge.net/tracker/index.php?func=detail&aid=1766613&group_id=180599&atid=893831
2. Cannot build kvm as external modules.

One new issue:
1. The speed of booting windows guest is very slow, top shows the cpu usage of qemu is always >100% while booting windows guest.
https://sourceforge.net/tracker/?func=detail&atid=893831&aid=1768187&group_id=180599

Issue list
================================================
1. Could not create kvm guest with memory >=2040 
https://sourceforge.net/tracker/index.php?func=detail&aid=1736307&group_id=180599&atid=893831
2. Create multiple guests simultaneously or create one guest many times may fail 
https://sourceforge.net/tracker/index.php?func=detail&aid=1741312&group_id=180599&atid=893831
3. Can not boot IA32e RHEL 4u3 guest with -no-acpi
https://sourceforge.net/tracker/index.php?func=detail&aid=1741314&group_id=180599&atid=893831
4. Can not boot 64 bit windows
https://sourceforge.net/tracker/index.php?func=detail&aid=1741318&group_id=180599&atid=893831
5. Some ltp test cases fail
https://sourceforge.net/tracker/index.php?func=detail&aid=1741316&group_id=180599&atid=893831
6. The speed of booting windows guest is very slow
https://sourceforge.net/tracker/?func=detail&atid=893831&aid=1768187&group_id=180599

This is an SMP guest?  What HAL does it use?

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

[Yunfeng] With ACPI HAL, both UP and SMP is slow. 
In my testing with 2 vcpus to boot win2k needs more than 4 minutes.(From
booting to network started).

This happens here too, with kvm versions as far back as kvm-20.  But 
with a clean install of Windows XP, it starts in about a minute (under 
the ACPI HAL) and idles using a few percent host cpu.  Looks like some 
Windows update causes this, not a kvm regression.

It's not a Windows update.  A new Windows install works well, as it will 
after all updates.  If you boot it in an smp configuration, however, it 
will update its kernel, and the new kernel will exhibit the problem, 
even if booted later with a single vcpu.

The guest will consume 100% cpu even though kvm_stat shows 6000 
exits/sec, which leads me to suspect the idle loop is spinning instead 
of executing a 'hlt' instruction.

[Yunfeng] In my case, the guest was installed with 2 vcpus, and then the
disk image works as a back file of qcow imgs. T
he smp windows test cases will boot the qcow img with 2vcpus.
My experience is that the installation speed of windows guest
(installing from iso file) is also slow.

I ran the same image under qemu 0.9.0, uniprocessor, and got the same 
results: high host cpu usage while the guest is idle.  Most likely the 
BIOS ACPI tables are misconfigured and the Windows idle loop is confused.

Do Xen SMP ACPI guests exhibit the same issues?  If not, they have 
probably fixed this issue in their bios.

[Yunfeng] Xen hasn't the issue.

Xen uses rev 2 acpi tables while the bochs bios uses rev 1.  Maybe the 
Windows smp kernel distrusts rev 1 acpi.
