| Thread-topic: | [PATCH] xend: passthrough: also do_FLR when a device is assigned |
To workaround a race condition about guest hotplug, c/s 18338:7c10be016e4 disabled do_FLR when we create guest or 'xm pci-attach' device into guest, so now we actually only do_FLR when a guest is destroyed or 'xm pci-detach'. By moving the FLR-related checking/do_FLR logic a little earlier, this patch re-enables do_FLR in these 2 cases disabled by 18338. Thanks, -- Dexuan
