I didn't say xm restore either. I was referring to the generic
save/restore functionality, though in fact I did use xl. And the
function I told you is in Xen hypervisor source code, not part of any
tool stack.

Whichever tools stack you use, it will eventually issue hypercall to Xen
via libxc. I don't use the same version as yours since I always plays
with xen staging unstable. However I don't think allocation code
has potential difference between 4.1.2 and staging unstable.


Wei.

I got it, but the error `
Âxc: error: do_evtchn_op: HYPERVISOR_event_channel_op failed: -1 (3 = No such process): Internal error.Â` said no such process, the system error description

didn't seem has anything to do with the following lines wich raisedÂ

Â85 Â Âstate->store_port = xc_evtchn_alloc_unbound(ctx->xch, domid, 0);

Â86 Â Âstate->console_port = xc_evtchn_alloc_unbound(ctx->xch, domid, 0);
