He just means c/s 26807 can work fine with this bug. It doesn''t mean the specific c/s 26807 is the bug fix c/s. I think some c/s before 26807 (and after 26440) fixed this bug.> Somehow I thought that the issue you faced would have been fixed with: > http://xenbits.xen.org/hg/xen-unstable.hg/rev/c00e71c4dd07 > (c/s 26860 ?) >I don''t think so. :-) because c/s 26807 can work well for the 32 vcpus issue.> > 2.

For xen c/s 26580, the repeatedly migration failed at the 2rd time. For the latest c/s 26961, we use qemu-upstream instead of traditional qemu-xen, then this bug can''t be reproduced now. We''ll have more update in the bugzilla before sending a new VMX status report.> > > > Fixed issues(3): > > =============> > 1.

It looks to work for me, but then I am > testing it with upstream kernels. >After upgrading the guest kernel to 3.8.9, basically it can work. ''xl vcpu-set'' can increase and decrease guest vcpu number with traditional qemu-xen. But, if I boot guest with 4 vcpus and ''maxvcpus=16'', then use ''xl vcpu-set $dom_id 16'' CMD to increase 12 vcpus in guest, the guest will call trace reporting "rcu_shed detected stalls on cpu/tasks". Increasing or decreasing vcpu number about 2 or 4 each time, it can work well. Note that ''maxvcpus=X'' config can''t be used with qemu-upstream. see: http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1837 We''ll have more update in the bugzilla before sending a new VMX status report.> > 5.
