Hi!
As far as I know you can do as usual. Enable the following:
| Code: | Processor type and features --->
[*] Paravirtualized guest support --->
[*] Xen guest support |
then:
| Code: | Device Drivers --->
Xen driver support --->
[*] Xen memory balloon driver (NEW)
[*] Scrub pages before returning them to system (NEW)
<*> Xen /dev/xen/evtchn device (NEW)
[*] Backend driver support (NEW)
<*> Xen filesystem (NEW)
[*] Create compatibility mount point /proc/xen (NEW)
[*] Create xen entries under /sys/hypervisor (NEW)
<M> userspace grant access device driver (NEW)
<M> User-space grant reference allocator driver (NEW)
<M> xen platform pci device driver (NEW)
[*] Network device support --->
< > Xen network device frontend driver
<*> Xen backend network device |
Try and let me know please.

I tried to start a VM and I had no one problem with this configuration. |
thank you for posting this kernel configuration

What changes are necessary for compiling a domU kernel? I haven't been able to disable the dom0 or privileged domain config flags or find any up to date documentation online.
I tried using menuconfig to disable the backend drivers but my domU boot hangs at "XENBUS: Waiting for devices to initialise"
here's the relevant bits of my .config:
| Code: | linux-3.0.6-gentoo-domU # grep XEN .config
CONFIG_XEN=y
CONFIG_XEN_DOM0=y
CONFIG_XEN_PRIVILEGED_GUEST=y
CONFIG_XEN_PVHVM=y
CONFIG_XEN_MAX_DOMAIN_MEMORY=128
CONFIG_XEN_SAVE_RESTORE=y
# CONFIG_XEN_DEBUG_FS is not set
# CONFIG_XEN_DEBUG is not set
CONFIG_PCI_XEN=y
CONFIG_XEN_PCIDEV_FRONTEND=y
CONFIG_XEN_BLKDEV_FRONTEND=y
# CONFIG_NETXEN_NIC is not set
CONFIG_XEN_NETDEV_FRONTEND=y
CONFIG_INPUT_XEN_KBDDEV_FRONTEND=y
CONFIG_HVC_XEN=y
# CONFIG_XEN_WDT is not set
CONFIG_XEN_FBDEV_FRONTEND=y
CONFIG_XEN_BALLOON=y
CONFIG_XEN_SCRUB_PAGES=y
CONFIG_XEN_DEV_EVTCHN=y
# CONFIG_XEN_BACKEND is not set
CONFIG_XENFS=y
CONFIG_XEN_COMPAT_XENFS=y
CONFIG_XEN_SYS_HYPERVISOR=y
CONFIG_XEN_XENBUS_FRONTEND=y
CONFIG_XEN_GNTDEV=m
CONFIG_XEN_GRANT_DEV_ALLOC=m
CONFIG_XEN_PLATFORM_PCI=m
CONFIG_SWIOTLB_XEN=y |
Am I missing something? |

No, I don't think so.
This is mine, and it works:
| Code: | CONFIG_XEN=y
CONFIG_XEN_DOM0=y
CONFIG_XEN_PRIVILEGED_GUEST=y
CONFIG_XEN_PVHVM=y
CONFIG_XEN_MAX_DOMAIN_MEMORY=128
CONFIG_XEN_SAVE_RESTORE=y
# CONFIG_XEN_DEBUG_FS is not set
# CONFIG_XEN_DEBUG is not set
CONFIG_PCI_XEN=y
CONFIG_XEN_PCIDEV_FRONTEND=y
CONFIG_XEN_BLKDEV_FRONTEND=y
# CONFIG_NETXEN_NIC is not set
CONFIG_XEN_NETDEV_FRONTEND=y
CONFIG_INPUT_XEN_KBDDEV_FRONTEND=y
CONFIG_HVC_XEN=y
# CONFIG_XEN_WDT is not set
CONFIG_XEN_FBDEV_FRONTEND=y
CONFIG_XEN_BALLOON=y
CONFIG_XEN_SCRUB_PAGES=y
# CONFIG_XEN_DEV_EVTCHN is not set
# CONFIG_XEN_BACKEND is not set
# CONFIG_XENFS is not set
# CONFIG_XEN_SYS_HYPERVISOR is not set
CONFIG_XEN_XENBUS_FRONTEND=y
# CONFIG_XEN_GNTDEV is not set
CONFIG_XEN_GRANT_DEV_ALLOC=m
CONFIG_XEN_PLATFORM_PCI=m
CONFIG_SWIOTLB_XEN=y |
Yours looks very similar to mine.

| Do you have to change or add anything to grub to get the hypervisor/dom0 features? |
