If I dump the xsd_kva page using mmap from another app, there are a
few entries made:
0000: 01 00 00 00 00 00 00 00 00 00 00 00 07 00 00 00
0010: 64 65 76 69 63 65 00 00 00 00 00 00 00 00 00 00
0020: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
...
0400: 10 00 00 00 00 00 00 00 00 00 00 00 07 00 00 00
0410: 45 4e 4f 45 4e 54 00 00 00 00 00 00 00 00 00 00
0420: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
...
0800: 17 00 00 00 17 00 00 00 00 00 00 00 17 00 00 00
As you indicate, lots of output in the xenstored-trace file, but hardly
anything here. We are getting some transactions in there though, so
maybe we're dealing with a memory ordering issue. Thanks,
Alex
