Hi. After "ipminative" driver has been removed (I think it was right decision), we support IPMI in ironic only via drivers which use "ipmitool" utility. This utility is mostly good, but main problem is that running by ironic subprocess can be stalled on buggy/broken BMCs. This causes situations like stop executing of sync power state periodic task without any logging, reduce free green threads number in the conductor service pool etc. Administrators often have only one version of ipmitool in repository and should build new version from source for bug fixing. We can implement custom executor for ipmitool with timeout for process, but this adds more complexity to IPMI drivers, or maybe use another solution? Maybe we should have pure Python well tested IPMI library optimized for ironic (like sushy for RedFish)?
