[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] RE: [Xen-devel] Domain save/migrate issue
My mentioning of the shared pages has brought up something else: How LIVE can the live migration become? What I mean is this: Right before the last iteration of the main xc_linux_save() main while loop, The domain is suspended. After the loop, the shared info pages are written. So, interrupts would be ignored, as xen won't send them to a shutdown domain. Seems obvious, but my point is that should there be a way to get xen out of suspended state, another improvement can be made: Xen can be made to write to event channels of suspended domains (up to a certain limit, and that capability can be turned on or off to finish things off...) Won't that mean that it would mean a lot less interrupts are lost? The migration would be even more LIVE. > _______________________________________________ > Xen-devel mailing list > Xen-devel@xxxxxxxxxxxxxxxxxxx > http://lists.xensource.com/xen-devel > > _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
