From: Yang Zhang <yang.z.zhang@Intel.com> The follwoing patches are adding the Posted Interrupt supporting to Xen: Posted Interrupt allows vAPIC interrupts to inject into guest directly without any vmexit. - When delivering a interrupt to guest, if target vcpu is running, update Posted-interrupt requests...

Xend will do a hypercall to destory domain when creating VTI guest fail. If "is_vti" not be set at this point, HV will call relinquish_vcpu_resource() which belong to domU. It may try to free a NULL pointer, so dom0 crash. This patch fix it.
