Xen devel - Nov 2007 - Xen unstable full validation results for cset: #16379

Hi all,

We finished a full testing for cset: #16379/#16461. Testing fields
include Control Panel, Guest Test, Installation, Performance, Stress,
Device Model, VTD and TXT etc. IPF/Xen results would be published alone.
We found 5 new bugs. The results show the pre-Xen3.2 should has a nice
status. 

Issue list:
--------------------------------
1. [TXT] In weybridge, tboot could not boot dom0 successfully 
2. [Stress] HVM RHEL5.1 guest crashed when running crashme. 
3. [Guest Test] SMP VISTA HVM guest might be blue screen when doing
large I/O in dom0 
4. [Device Model] HVM''s ne2k NIC easily lose network. 
5. [Device Model] vnif can not coexist with 8139 nic. 
6. [Installation] Fedora8 IA32e guest installation failure.
7. [Installation] Fedora7 IA32 SMP guest installation failure.

The detailed results please reference the attachment.

Thanks, this is valuable work, and good news to receive.

I assume the usual Intel folks will look into this.

Is this the ioport emulation issue that was discussed on the list today?

This is under investigation.

Please can you give more details. Is there any guest that actually
requires ne2k anyhow?

HVM? Do you test the PV kernel as well?
> 7. [Installation] Fedora7 IA32 SMP guest installation failure.
HVM? Do you test the PV kernel as well? Is the install crash the same as
FC8?

Thanks,
Ian

Yes. Intel developer are looking at the issue.

Dexuan sent out a patch to work around this issue: [PATCH][HVM] Inject
#GP for un-emulated instructions rather than crash guest

We found this issue on some 2 cores machines. When scp a large file (5G)
to Dom0, SMP VISTA HVM might blue screen. If using disk stress tool, the
problem would be more easy to see. The BSOD information is: "a clock
interrupt was not received on a secondary processor within the allocated
time interval" with Bug Check 0x101.

Should be not. As ne2k is a optional config for HVM domain vif, so we
also tested it. But found ne2k is not easy to use like RTL 8139.
If so, we could remove the ne2k description in xmexmaple.hvm. :)

Yes. It is HVM domain. We didn''t try PV installation. The Qemu window
would disappear, when doing RPM installation. 
The special config is "vcpus=2 acpi=1 apic=1 pae=1 memory=1024
blank_disk=5G."

Yes. This is also HVM domain OS installation. It is not same with F8.
The installation kernel would hang. It is a SMP IA32 Fedora7.
