Hi,
On a stock Debian GNU/Linux 10 (buster) running kernel 4.19.0-6-rt-amd64 #1 SMP PREEMPT RT Debian 4.19.67-2+deb10u1 (2019-09-20)
with Xen 4.11...
I keep getting the errors below when trying to boot guests, related to xen_evtchn it seems.
They usually don't boot, even though sometimes they do but very rarely. Can
someone shed some light? I've tried the next kernel available for Buster,
5.2.0-0.bpo.3-rt-amd64, but I get with exactly the same issues...
Thanks,
jf
