Hi, The following patch series fixes hangup after creating checkpoint on Xen. The Linux Xen guest can be saved the state to restore later, and also created snapshot like checkpoint via the hypervisor. But, when the snapshot is created for the PV guest, it will hangup. We added ''PMSG_CANCEL'' message and ''cancel'' handler in dev_pm_ops struct in the pm-linux
