Hi all, In previous configs, I knew that I could panic a RHEL/CentOS KVM VM with 'echo c > /proc/sysrq-trigger' and the guest would halt entirely, allowing vm.sh/rgmanager to detect the fault and reboot the guest. Now though, when trying it again recently, I noticed that the guest's CPU sat pegged at 50% (2 vcpus, so probably one core pegged). This seems to have prevented the failure from being detected, so the system was not recovered. Following here: https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/s2-proc-dir-sys.html#s3-proc-sys-kernel I tried; 'echo 1 > /proc/sys/kernel/sysrq', I tried with selinux in permissive and enforcing mode and I tried with RHEL 6.4 and 6.5. In all cases, the guest's vcpu stayed active and rgmanager was unable to detect the fault. I know that I can set; 'echo 5 > /proc/sys/kernel/panic' and have RHEL auto-reboot post panic, but I'd like to know if it's possible to have rgmanager actually detect the crash when this is not configured. Is there a way to tell RHEL specifically/Linux in general to cease all activity when it panic's?
