Hi!
After cleanin metadata yum do an update of vdsm:

[root@ovirt01 ~]# rpm -qva | grep vdsm
vdsm-yajsonrpc-4.18.4.1-0.el7.centos.noarch
vdsm-infra-4.18.4.1-0.el7.centos.noarch
vdsm-cli-4.18.4.1-0.el7.centos.noarch
vdsm-python-4.18.4.1-0.el7.centos.noarch
vdsm-hook-vmfex-dev-4.18.4.1-0.el7.centos.noarch
vdsm-xmlrpc-4.18.4.1-0.el7.centos.noarch
vdsm-4.18.4.1-0.el7.centos.x86_64

vdsm-gluster-4.18.4.1-0.el7.centos.noarch
vdsm-jsonrpc-4.18.4.1-0.el7.centos.noarch

Hi!
I've just upgrade oVirt from 3.6 to 4.0 and I'm not able to start
the self hosted engine.

Hi Stefano, can you please try "yum clean metadata" "yum update"
again?

issue.
