Hi all,
I recently updated from xen-4.6.6 to xen-4.8.2 and I am unable to start any
guest that previously worked without issue under 4.6.6. The create process
fails with the following:
libxl: debug: libxl_event.c:636:libxl__ev_xswatch_register: watch

Reading on similar issues in the past, I have validated that the versions of
xen libraries are all 4.8.2:
xen-runtime-4.8.2-3.el6.x86_64
xen-ocaml-4.8.2-3.el6.x86_64

If I roll back to my 4.6.6 version of xen using the same kernel (4.4.102),
the guest starts without issue.
Attached is the full output from "xl -vvvv create" when using xen 4.8.2. Any
suggestions is greatly appreciated.
Best regards,
Alex
