Hi All, I have a 5.4 box and testing xen 3.4 on kernel-xen-2.6.18-164.6.1.el5. As you know, there are no enough configuration to do "Suspend to Disk" of the .config of the kernel-xen-2.6.18-164.6.1.el5. # Power management options (ACPI, APM) # CONFIG_PM=y Then, I tied to get the kernel-2.6.18-164.6.1.el5.src. rpm, installed that. #pwd /usr/src/redhat/BUILD/kernel-2.6.18/linux-2.6.18.i686 #cp configs/kernel-2.6.18-i686-xen.config .config #make menuconfig Power management options (ACPI, APM) ---> ACPI (Advanced Configuration and Power Interface) Support ---> │ │ │ │ CPU Frequency scaling ---> │ │ There are no menu which likes "Legacy Power Management API". How can I add the options to enable the Supend to Disk? Yukio -------------- next part -------------- An HTML attachment was scrubbed...
