[ovirt-users] Odd messages on new node/hosted engine

I built a new node+hosted engine setup, using up-to-date 6.5 and oVirt 3.4.3-RC. I see some odd messages, that I think are probably related: - In the hosted engine UI, I have an Alert that says "Failed to verify Power Management configuration for Host hosted_engine_1." - On the node, I get the following chunk repeated every 10 seconds in /var/log/messages: Jul 16 14:34:19 node0 kernel: device-mapper: table: 253:2: multipath: error getting device Jul 16 14:34:19 node0 kernel: device-mapper: ioctl: error adding target to table Jul 16 14:34:19 node0 kernel: device-mapper: table: 253:2: multipath: error getting device Jul 16 14:34:19 node0 kernel: device-mapper: ioctl: error adding target to table Jul 16 14:34:19 node0 multipathd: dm-2: remove map (uevent) Jul 16 14:34:19 node0 multipathd: dm-2: devmap not registered, can't remove Jul 16 14:34:19 node0 cpuspeed: Disabling performance cpu frequency scaling governor Jul 16 14:34:19 node0 multipathd: dm-2: remove map (uevent) Jul 16 14:34:19 node0 multipathd: dm-2: devmap not registered, can't remove Jul 16 14:34:19 node0 multipathd: dm-2: remove map (uevent) Jul 16 14:34:19 node0 multipathd: dm-2: devmap not registered, can't remove Jul 16 14:34:19 node0 multipathd: dm-2: remove map (uevent) Jul 16 14:34:19 node0 multipathd: dm-2: devmap not registered, can't remove Jul 16 14:34:20 node0 cpuspeed: Enabling performance cpu frequency scaling governor There is no dm-2; the system is installed on 2 SAS drives, mirrored using Linux md RAID1, using LVM (dm-0 is the root filesystem and dm-1 is swap).
