Working with Xen 4.9.0 host on kernel 4.11.3
dmesg | egrep -i "linux version|xen version"
[ 0.000000] Linux version 4.11.3-2.g7262353-default
(geeko@buildhost) (gcc version 7.1.1 20170517 [gcc-7-branch revision 248152]
(SUSE Linux) ) #1 SMP PREEMPT Thu May 25 17:55:04 UTC 2017 (7262353)
[ 0.000000] Xen version: 4.9.0_07-503 (preserve-AD)
I currently see in host boot
dmesg | grep sysrq
[ 20.905146] xen:manage: Unable to read sysrq code in
control/sysrq
That seems to originate at
https://lkml.org/lkml/2016/11/8/134
...
+ if (xenbus_scanf(xbt, "control", "sysrq", "%c", &sysrq_key) <
0) {
pr_err("Unable to read sysrq code in control/sysrq\n");
xenbus_transaction_end(xbt, 1);
return;
...
Is this a config issue -- wrong or missing -- on my end? Or a problem that
needs some more diagnostic info here?
