Hello,
Sorry for the delay, there was a huge can of worms behind this. I have a
solution, but it requires patching both Xen and the FreeBSD kernel. Please bear
with me, I will send those patches once ready.
It sounds like you might know this already, but I did some more digging
and here is what I can see so far...
The important command is "xl devd". Running that under truss, it is
trying to open /dev/xen/xenbus and that was the cause of the No such
file error. It looks like the 10.3 tools used to open /dev/xen/xenstore
instead.
I can get around this by exporting XENSTORED_PATH="/dev/xen/xenstore".
Now xl devd is stuck at:
libxl: error: libxl_event.c:639:libxl__ev_xswatch_register: create watch
for path /local/domain/7/backend: Invalid argument
So it seems like an API issue with asking the kernel or dom0 to set a
watch for new backend devices.
Whenever the patches are ready I can test them on my system.
