Hi Sai
Could you please let me know the values you have configured for the following global settings. I have used the following values and KVM host ha is working fine. Also can you check by executing the following api https://cloudstack.apache.org/api/apidocs-4.20/apis/issueOutOfBandManagementPowerAction.html The ipmi tool on management server should restart the host ipmitool [options] power cycle ipmitool -I lanplus -U admin -P password -H 127.0.0.1 power status Global settings ("kvm.ha.activity.check.failure.ratio", "0.6") ("kvm.ha.activity.check.interval", "8") ("kvm.ha.activity.check.max.attempts", "5") ("kvm.ha.activity.check.timeout", "30") ("kvm.ha.degraded.max.period", "30") ("kvm.ha.fence.timeout", "30") ("kvm.ha.health.check.timeout", "30") ("kvm.ha.recover.failure.threshold", "2") ("kvm.ha.recover.timeout", "30") ("kvm.ha.recover.wait.period", "30") Regards Kiran From: sai <sai.kr...@gmail.com> Date: Monday, 20 January 2025 at 9:43 PM To: users@cloudstack.apache.org <users@cloudstack.apache.org> Subject: Re: KVM Host HA Hi, Yes, can you please elaborate on the statement "Host HA is known to break VM HA". I have tried multiple times HA state is in degraded state on kernel panic and vm never get migrated and HA doesn't change from degraded state.
