Hi Wing and Yongkang,

Oh! I am sorry that it was caused by my patch. I will review my patch.

Best regards, Kan

Hi Kan: <f000000007b30080> is an address belong to free_domheap_pages(). I found if reversed your patch, the issue will not meet. Could you give a review to your patch, maybe there is something lost.

Hi Yongkang,

Hmmm... It's the strange issue. I think so, too. I'm trying to reproduce the strange issue. But I'm not able to meet the strange issue at this stage. Currently, the creation of HVM domain does not call the pervcpu_vhpt_free() by my patch(changeset:13434). Which function is <f000000007b30080>?

Best regards, Kan

Hi all,

This is a strange issue, because some machines do not meet this problem, including our daily regular testing machine.

But we found Xen might crash when doing the operation of creating VTI in some other machines. Serial console would keep report: ... (XEN) [<f000000004080300>] pervcpu_vhpt_free+0x30/0x50 (XEN) sp=f000000007bffe00 bsp= f000000007bf93e8 (XEN) [<f000000007b30080>] ??? (XEN) sp=f000000007bffe00 bsp= f000000007bf93e8 ...

We found this issue at least in 13438 and 13465. Does anybody meet this issue too?

Best Regards, Yongkang (Kangkang) モタソオ
