[ovirt-users] HostedEngine and affinity groups

Hi, i operate a 3 node ovirt42 cluster (hyperconverged). Now i would like to isolate the HostedEngine from the other VMs. The reason is to minimize the impact of outage of one of the nodes. When the node with the HE is away there is no impact at all on the running VMs. If one of the other nodes goes down, then i have still a running HE which restarts the missing VMs on remaining nodes fast again. I cannot use hard affinity because in case of failure i need all resources of the 2 remaining modes, so i configured a soft negative affinity group for every VM between this VM and the HE. As a first test i migrated the HE to a node with VMs but even after a while nothing happened. I would have expected that either the HE or the VMs on this node would have been migrated to fullfill the soft negative affinity. Now my questions: Are my thoughts correct? Is there a better solution than making one (soft negative) affinity group for every VM to isolate from HE? Does the affinity group enforcement engine work at all with soft rules? Regards, Robert
