Hi Victor, What parameters do you have for:
kvm.ha.activity.check.max.attempts kvm.ha.activity.check.interval kvm.ha.activity.check.timeout kvm.ha.health.check.timeout kvm.ha.degraded.max.period the logs should show entries relating to these, BUT.... it's possible that as you performed a clean shutdown, the agent could have sent a shutdown ack to the management server, so the management server may no longer be polling. I'm not sure about that scenario. I recently used: echo c > /proc/sysrq-trigger as suggested by Nux, to simulate a host crash. paul.an...@shapeblue.com www.shapeblue.com 53 Chandos Place, Covent Garden, London WC2N 4HSUK @shapeblue -----Original Message----- From: victor <vic...@ihnetworks.com> Sent: 07 March 2018 17:02 To: users@cloudstack.apache.org Subject: KVM HostHA Hello Guys, I have installed cloudstack 4.11. I have enabled HA for each hosts I have added. I have also added ipmi successfully (using ipmi driver). The hosts are showing like the following. ======= HA Enabled Yes HA State Available HA Provider kvmhaprovider ====== Also the host is showing the following correctly Resource state --> Enabled State --> UP Power state --> On So I have shutdown one of the hosts to see how the KVM hosts Ha is working. I have waited for half an hour. But nothing has happened. What will happen to the VM's in that host, if the host failed to back up. There isn't much from logs. Regards Victor
