Here
In vdsm log I see that you installed hosted engine on NFS storage domain; not having multipath devices and ovirt vgs/lvs is expected. Your multipath errors may be related to ovirt, but only because vdsm requires and starts multipathd, and install new multipath.conf. I suggest to try to get help about it in device-mapper channels (e.g. #lvm on freenode). If you cannot resolve this, please open a bug. Nir

After ovirt installation on host console I see this error every 5 minutes:
[ 1823.837020] device-mapper: table: 253:4: multipath: error getting device [ 1823.837228] device-mapper: ioctl: error adding target to table This may be caused by the fact that vdsm does not cleanup properly after deactivating storage domains. We have an open bugs on this.
You may have an active lv using non-existent multipath device.
Can you share with us the output of:
lsblk multipath -ll dmsetup table cat /etc/multipath.conf pvscan --cache > /dev/null && lvs
Nir
See above:

There are no multipath devices in this host and no ovirt storage domains lvs.
Nir
Yes this is the host. I'm sure. I've not yet configured ovirt storage domains (only installed ovirt on host and self hosted engine VM)
