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

libxl: error: libxl_utils.c:820:libxl_cpu_bitmap_alloc: failed to retrieve

[ 696.810334] xenbr0: port 1(vif2.0) entered disabled state

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

/local/domain/1/backend/vif/2/0/state wanted state 2 still waiting state 5
There's something wrong with the negotiation between the frontend and
the backend AFAICT. The backed switches to state 5 and 6 (Closed) so
the connection cannot be established.
Can you paste the output of `xenstore-ls -fp` from dom0 after `xl
devd` reports the timeout?

What OS/versions are you using for the guest and the driver domain, do
you have any local modifications?
I'm using the same OS for everything: dom0 and guestX. It is petalinux
2021.2.
Regards, Roger.
