Subject: where the vcpu-s switching is happen
Date: Sun, 2 Mar 2014 10:44:22 -0800 (PST) [thread overview]
Message-ID: <1393785862763-5721477.post@n5.nabble.com> (raw)
Hi all,
I wlould like to ask where is the code where the switching of vcpu-s on one
physical cpu is happening?
If i use x86 and vmx mode i think that the actual switch i happen in
vmx_ctxt_switch_to(struct vcpu *v) at vmx.c file.
I think the vmx_restore_guest_msrs(v) function is responsible for restoring
the registers of the guest and the RIP register - which is the real task
switching between vcpus.
i'm not sure but i would like to ask where the RIP register is changed with
the new vcpu's instuction pointer?
as far as i know the RIP register is stored at VMCS controll stucture and it
is loaded when that structure become active ...
plase help with some hints about this proccess.
Best Regards
