[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] RE: [PATCH] blktap2 - human readable output for tapdisk2 creation problems.
hi, with this patch. i can not see extra info in xend.log
it still show the error:
Error: Device 768 (tap) could not be connected. Setting up the backend failed.
See the log files in /var/log/xen/ for details.
i have take a look at this issue. seems the tap 768 hotplug-status return
error. Before cs 19647. it always is connected.
here is xend.log:
