I tested save/restore of a hvm domain but not a pv!, I have just tested it and found that it does not work unless I use a kernel that has dom0 support enabled , this is because the menu option to select CONFIG_SUSPEND Depends on: !XEN_UNPRIVILEGED_GUEST so unless you select CONFIG_XEN_PRIVILEGED_GUEST (dom0 support) you cannot enable it when building a Xen kernel, however a simple change to drivers/xen/Kconfig will enable CONFIG_SUSPEND automatically for domU only kernels: At line 21 or thereabouts add "select SUSPEND": config XEN_UNPRIVILEGED_GUEST def_bool !XEN_PRIVILEGED_GUEST select PM select PM_SLEEP select SUSPEND select PM_SLEEP_SMP if SMP Save/Restore then seems to work ok apart from some errors logged in the domU: i686: ------------[ cut here ]------------ WARNING: at kernel/irq/manage.c:273 __enable_irq+0x32/0x5b() Unbalanced enable for IRQ 518 Modules linked in: Pid: 3087, comm: suspend Tainted: G W 2.6.31-xen-r9 #1 Call Trace: [<c0157037>] ?
