Hi all, I'm not sure whether this is related to Atom2's post "substantial shutdown delay for PV guests with PCI -passthrough", I didn't see any resolution to it and I am seeing something similar, but slightly different. I get a 10s delay shutting down my PV, I have implemented the code as I see it in mini-os: 1.- frontend sets state XenbusStateClosing and waits for backend to go to state >= XenbusStateClosing. 2.- frontend sets state XenbusStateClosed and waits for backend to go to state >= XenbusStateClosed 3.- frontend set state XenbusStateInitialising and waits for frontend to go to a state in the interval [XenbusStateInitWait, XenbusStateClosed). If I perform step 3 then the frontend never exits as the backend state stays at XenbusStateClosed If I do not perform step 3 then PV shutsdown after a 10s timeout. Is this mini-os implementation in sync with the pciback implementation? Is there a step I have missed? -- Best regards, Simon mailto:furryfuttock@xxxxxxxxx _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
