...save and release whole memory of domU after suspended, since it allows more memory available to other domains. However for platform level S3, this is redundant when box is physically put into a suspend state. What we need is just to send a suspend notification into domU, and let domU fall into __xen_suspend path. Then domU exits scheduler by issuing HYPERVISOR_suspend. Nothing else required after this. After resume, domU just continues to run after suspend point. Even __xen_suspend path is a bit heavy, and in this case resources don''t change for domU even after resume. Maybe we can bene...

Hi, I have uploaded a new set of rebased openSUSE dom0 xen patches and Gentoo ebuild for 2.6.31 to http://code.google.com/p/gentoo-xen-kernel/downloads/list, Jan Beulich recently identified the cause of the null pointer crash and other stability problems that affected previous versions and with the necessary fixes applied the kernel has run for 2+ days with no issues at all, I think you will find

Here''s a question about FE driver and log dirty, when live migration is concerned. Log dirty mode is used in live migration, which works for those polluted pages from CPU issued accesses, but not for DMA path (as BE driver talked here which access from another domain like dom0). Most frontend drivers don''t implement their own suspend interface (netfront implements when

Stamp softlockup thread earlier before do_timer, because the latter is the one to actually trigger lock warning for long-time offline. Or else, I obserevd softlockup warning easily at manual vcpu hot-remove/plug, or when suspend cancel into old context. One point here is to cover both stolen and blocked time to compare with offline threshold. vcpu hotplug falls into ''stolen''
