You can upgrade vdsm without upgrading to ovirt 4.  I went through the
same issue on our cluster a few weeks ago and the process was pretty
simple.

You'll need to do this on each of your hosts.

yum --enablerepo=extras install -y epel-release git
git clone https://github.com/oVirt/vdsm.git
cd  vdsm
git checkout v4.17.35
yum install -y `cat ./automation/build-artifacts.packages`
./automation/build-artifacts.sh

cd /root/rpmbuild/RPMS/noarch
yum --enablerepo=extras install centos-release-qemu-ev
yum localinstall vdsm-4.17.35-1.el7.centos.noarch.rpm  vdsm-hook-vmfex-dev-4.17.35-1.el7.centos.noarch.rpm vdsm-infra-4.17.35-1.el7.centos.noarch.rpm vdsm-jsonrpc-4.17.35-1.el7.centos.noarch.rpm vdsm-python-4.17.35-1.el7.centos.noarch.rpm vdsm-xmlrpc-4.17.35-1.el7.centos.noarch.rpm vdsm-yajsonrpc-4.17.35-1.el7.centos.noarch.rpm vdsm-python-4.17.35-1.el7.centos.noarch.rpm vdsm-xmlrpc-4.17.35-1.el7.centos.noarch.rpm vdsm-cli-4.17.35-1.el7.centos.noarch.rpm
systemctl restart vdsmd

The qemu-ev repo is needed to avoid dependency errors.
