[Xen-devel] Grant Table Error on 2.6.32.36 + Xen 4.0.1
Hi:
We are just about to try the new Kernel, but confront Error on grant table.
2.6.32.36 Kernel: http://git.kernel.org/?p=linux/kernel/git/jeremy/xen.git;a=commit;h=bb1a15e55ec665a64c8a9c6bd699b1f16ac01ff4
Xen 4.0.1 http://xenbits.xen.org/hg/xen-4.0-testing.hg/rev/b536ebfba183
Our test is simple, 24 HVMS(Win2003 ) on a single host, each HVM loopes in restart every 15minutes.
Please refer to error log from serial output
I've traced the log a bit, and the log is from xen/common/grant_table.c
1) log " grant_table.c:1717:d0 Bad grant reference 4294965983 " if from
1715 if ( unlikely(gref >= nr_grant_entries(rd->grant_table)) ){
1716 PIN_FAIL(unlock_out, GNTST_bad_gntref,
1717 "Bad grant reference %ld\n", gref);
1718 BUG();
1719 }
2) log "grant_table.c:266:d0 Bad flags (0) or dom (0). (expected dom 0) " is from
grant_table.c:1967 => __acquire_grant_for_copy => _set_status
( not from __gnttab_map_grant_ref, since I add some log to identify this )
The log shows that all are from gnttab_copy, which I later found only netback
has grant copy hypercall.
I also tried netback code from 2.6.31(which works well with kernel 2.6.31), but
still met these errors. So it looks like it is kernel related.
What happened for this, will this harmful for the usage of HVM?
Many thanks.
