Unfortunately this didn't work. I tried also to disable totally selinux without success. Then I decided to install gtk2 manually with the --skip-broken option, and apparently everything went fine. After this, the host installation goes on without errors. It says "Installation is closing up", then gets stuck indefinitely. Now the host-engine looks dead or messed up, even after a reboot... more in detail, the web portal is no longer accessible. :( On 30 July 2017 at 10:58, Yanir Quinn <yquinn(a)redhat.com&gt; wrote: > Might be a selinux related issue, similar threads suggest either to > disable selinux completely or run on host: > > # setenforce 0 > # yum clean expire-cache > # yum update selinux-policy\* > # setenforce 1 > > keeping an eye out for other reasons/solutions. > > Regards, > Yanir Quinn > > On Thu, Jul 27, 2017 at 5:32 PM, Iurcev, Massimiliano <miurcev(a)inogs.it&gt; > wrote: > >> I installed ovirt-engine on Centos7.
