[ovirt-users] Host ovritnode1 installation failed. Command returned failure code 1 during SSH session 'root at X.X.X.X'.

[M.I.S]

hi,
   I encountered a problem.
   I am getting an error when adding a host to ovirt-engine:Host ovritnode1 installation failed. Command returned failure code 1 during SSH session 'root at 192.168.1.152'.
   PS: all user and password is correct.


I checked engine log, the information is as follows:
