Hi all,

according to the conversation that I had with royger, aa67b97ed34  broke the 
driver domain support.

What I'm trying to do is to setup networking between guests using driver 
domain. Therefore, the guest (driver) has been started with the following cfg.

name    = "guest0"
kernel  = "/media/sd-mmcblk0p1/Image"
ramdisk = "/media/sd-mmcblk0p1/rootfs.cpio.gz"
extra   = "console=hvc0 rdinit=/sbin/init root=/dev/ram0"
memory  = 1024 vcpus   = 2
driver_domain = 1

On guest0 I created the bridge, assigned a static IP and started the udhcpd on 
xenbr0 interface.
While the second guest has been started with the following cfg:

name    = "guest1"
kernel  = "/media/sd-mmcblk0p1/Image"
ramdisk = "/media/sd-mmcblk0p1/rootfs.cpio.gz"
extra   = "console=hvc0 rdinit=/sbin/init root=/dev/ram0"
memory  = 1024 vcpus   = 2
vcpus   = 2
vif = [ 'bridge=xenbr0, backend=guest0' ]

Follows the result of strace xl devd:

# strace xl devd
execve("/usr/sbin/xl", ["xl", "devd"], 0xffffdf0420c8 /* 13 vars */) = 0



ioctl(5, _IOC(_IOC_NONE, 0x50, 0, 0x30), 0xffffe6e41b40) = -1 EPERM (Operation 
not permitted)
write(2, "libxl: ", 7libxl: )                  = 7
write(2, "error: ", 7error: )                  = 7
write(2, "libxl_utils.c:820:libxl_cpu_bitm"..., 
87libxl_utils.c:820:libxl_cpu_bitmap_alloc: failed to retrieve the maximum number of 
cpus) = 87
write(2, "\n", 1
)                       = 1
clone(child_stack=NULL, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, 
child_tidptr=0xffff9ee7a0e0) = 814
wait4(814, [{WIFEXITED(s) && WEXITSTATUS(s) == 0}], 0, NULL) = 814
--- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=814, si_uid=0, 
si_status=0, si_utime=2, si_stime=2} ---


xl devd is daemonizing, but strace is only following the first
process.  Use `strace xl devd -F` to prevent the daemonizing (or
`strace -f xl devd` to follow children).


Or as a first step try to see what kind of messages you get from `xl
devd -F` when trying to attach a device using the driver domain.


Nothing has changed. On guest0 (the driver domain):

# xl devd -F
libxl: error: libxl_utils.c:820:libxl_cpu_bitmap_alloc: failed to retrieve
the maximum number of cpus
libxl: error: libxl_utils.c:820:libxl_cpu_bitmap_alloc: failed to retrieve
the maximum number of cpus
libxl: error: libxl_utils.c:820:libxl_cpu_bitmap_alloc: failed to retrieve
the maximum number of cpus

[  696.810334] xenbr0: port 1(vif2.0) entered disabled state
[  696.824518] device vif2.0 entered promiscuous mode


Can you use `xl -vvv devd -F` here?
