Hi Aleksey,

the error message is raised by Host upgrade manager (more info at [1]) which checks for available package upgrades on the host.

It seems that you have somehow corrupted repository configuration of the host '​kom-ad01-vm31.holding.com':

​2016-09-12 02:00:13,300 ERROR [org.ovirt.engine.core.bll.hostdeploy.VdsDeployBase] (VdsDeploy) [] Yum Cannot queue package iproute: Cannot find a valid baseurl for repo: base/7/x86_64
2016-09-12 02:00:13,304 ERROR [org.ovirt.engine.core.bll.hostdeploy.VdsDeployBase] (VdsDeploy) [] Failed to execute stage 'Environment packages setup': Cannot find a valid baseurl for repo: base/7/x86_64

Could you please verify that you are able to successfully execute following commands on the host?

  yum check-update
  yum update vdsm vdsm-cli


Thanks
