Configure kernel for domU support

    If building 32 bit kernel make sure you have CONFIG_X86_PAE enabled (which is set by selecting CONFIG_HIGHMEM64G)
        non-PAE mode doesn't work in 2.6.25, and has been dropped altogether from 2.6.26 and newer kernel versions.
    Enable these core options (Processor type and features| Paravirtualized guest support]
        CONFIG_PARAVIRT=y
        CONFIG_XEN=y
        CONFIG_PARAVIRT_GUEST=y
        CONFIG_PARAVIRT_SPINLOCKS=y
    And Xen pv console device support (Device Drivers|Character devices
        CONFIG_HVC_DRIVER=y
        CONFIG_HVC_XEN=y
    And Xen disk and network support (Device Drivers|Block devices and Device Drivers|Network device support)
        CONFIG_XEN_FBDEV_FRONTEND=y
        CONFIG_XEN_BLKDEV_FRONTEND=y
        CONFIG_XEN_NETDEV_FRONTEND=y
    And the rest (Device Drivers|Xen driver support)
        CONFIG_XEN_PCIDEV_FRONTEND=y
        CONFIG_INPUT_XEN_KBDDEV_FRONTEND=y
        CONFIG_XEN_FBDEV_FRONTEND=y
        CONFIG_XEN_XENBUS_FRONTEND=y
        CONFIG_XEN_SAVE_RESTORE=y
        CONFIG_XEN_GRANT_DEV_ALLOC=m
    And for tmem support:
        CONFIG_XEN_TMEM=y
        CONFIG_CLEANCACHE=y
        CONFIG_FRONTSWAP=y
        CONFIG_XEN_SELFBALLOONING=y

Configure kernel for dom0 support

NOTE: Xen dom0 support depends on ACPI support. Make sure you enable ACPI support or you won't see Dom0 options at all.

In addition to the config options above you also need to enable:

    CONFIG_X86_IO_APIC=y
    CONFIG_ACPI=y
    CONFIG_ACPI_PROCFS=y (optional)
    CONFIG_XEN_DOM0=y
    CONFIG_PCI_XEN=y
    CONFIG_XEN_DEV_EVTCHN=y
    CONFIG_XENFS=y
    CONFIG_XEN_COMPAT_XENFS=y
    CONFIG_XEN_SYS_HYPERVISOR=y
    CONFIG_XEN_GNTDEV=y
    CONFIG_XEN_BACKEND=y
    CONFIG_XEN_NETDEV_BACKEND=m
    CONFIG_XEN_BLKDEV_BACKEND=m
    CONFIG_XEN_PCIDEV_BACKEND=m
    CONFIG_XEN_PRIVILEGED_GUEST=y
    CONFIG_XEN_BALLOON=y
    CONFIG_XEN_SCRUB_PAGES=y
    CONFIG_XEN_DEV_EVTCHN=y
    CONFIG_XEN_GNTDEV=y

If you're using RHEL5 or CentOS5 as a dom0 (ie. you have old udev version), make sure you enable the following options as well:

    CONFIG_SYSFS_DEPRECATED=y
    CONFIG_SYSFS_DEPRECATED_V2=y

For more current Xen related config options check the example .config files from the troubleshooting section, and check the 2.6.18-to-2.6.31-and-higher wiki page.
