[Xen-ia64-devel] Weekly Xen-IA64/VTI status report.

["You, Yongkang" <yongkang.you@xxxxxxxxx>]

Hi all,

In this week, Xen0 met 1 day building fail and xenU seemed not too stable. VTI 
domain has not show stop bug.

Major Issues:
1. After create VTI domain and XenU for several times (sometimes creating multi 
domain at the same time), XenU maybe not be created successfully. Serial port 
report " Domain 49 (vcpu#0) crashed on cpu#3 ". I put the log to attachment. 
When XenU can not be created, but VTI domain can be created successfully. I 
didn't find the effective way to reproduce. Just meet 3 times. This issue is 
found in Cset 9992 and 9996.
2. xend.log reports "DEBUG (blkif:24) exception looking up device number f
or hda1: [Errno 2] No such file or directory: '/dev/hda1' " when creating xenU. 

I just found above two issues and didn't report it to mailing list separately. 

Bugs fixed:
1. Xen0 (more than 270 times) and XenU kernel build won't meet "Segmentation 
Fault". ***
2. VTI domain won't crash when running LTP testing cases.
3. Qemu Window disappeared issue also didn't be found for several days.

For nightly testing, most of cases could pass. Case 5 (2 XenU coexisting) are 
failed in nightly testing because the issue 1. But it can pass when running 
alone. Please see the attachment for the detail. I will put some information 
about full LTP testing (including stress) of VTI domain next week.

1 UP VTI creating/destroying                            Pass
1 UP XenU creating/destroying                           Pass
LTP testing in UP VTI                                           Pass
1 UP VTI + 1 XenU creating/destroying           Pass

2 UP VTI creating/destroying                            Pass
