I see you have just added sata to pve-manager, ahci is unmigratable for the moment, http://git.qemu.org/?p=qemu.git;a=blob;f=hw/ide/ich.c;h=272b7734b55f5e777d43c272ffbef8cc9ade0ac9;hb=HEAD static const VMStateDescription vmstate_ahci = { .name = "ahci", .unmigratable = 1, }; so I think we should add a check for live migration
