Hi,

I had config a HVM domU, but when I call function xc_domain_unpause() it is going to reboot, I find that when I call xc_domain_unpause(), it can call a hypercall, but when the hypercall finished, some flag of kernel changed. The flag include shutdown_reason. In the same time, the domU stoped.

The program run well in xen 3.2, but now it is xen 3.4, it can not work. Can anybody help me, or tell me how to debug hypercall layer in xen!

 

Thanks
