Hi all, We are trying to install the new release of OVIRT 4.2.6 on freshly installed machines based on RHEL 7.5. First of all, we encountered a strange error when install the ovirt-release42 package, it adds the necessary public repositories on /etc/yum.repos.d/, but after do that, sometimes when we try to update or install the other required packages we saw: Cannot find a valid baseurl for repo: ovirt-4.2/$releasever Why cannot configure this path variable automatically or what can influence to obtain this problem? In the other hand, when the repos sometimes are well configured and we can install the packages correctly, we found other problems related to the deploy of the ovirt-engine (OVA appliance based). Trying through cockpit, we found this error: [ ERROR ] fatal: [localhost]: FAILED! => {"changed": true, "cmd": ["virt-install", "-n", "HostedEngineLocal", "--os-variant", "rhel7", "--virt-type", "kvm", "--memory", "16348", "--vcpus", "4", "--network", "network=default,mac=00:16:3e:05:c3:66,model=virtio", "--disk", "/var/tmp/localvmj4Y_f1/images/65f7f081-4d9e-43ae-926f-25807f075f1d/a0a00e73-d3ea-4b9b-bd26-06fe189931f2", "--import", "--disk", "path=/var/tmp/localvmj4Y_f1/seed.iso,device=cdrom", "--noautoconsole", "--rng", "/dev/random", "--graphics", "vnc", "--video", "vga", "--sound", "none", "--controller", "usb,model=none", "--memballoon", "none", "--boot", "hd,menu=off", "--clock", "kvmclock_present=yes"], "delta": "0:00:02.122539", "end": "2018-09-06 00:44:18.089510", "msg": "non-zero return code", "rc": 1, "start": "2018-09-06 00:44:15.966971", "stderr": "/usr/lib/python2.7/site-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.21.1) or chardet (2.2.1) doesn't match a supported version!\n RequestsDepen dencyWarning)\nERROR internal error: qemu unexpectedly closed the monitor: qemu: could not load PC BIOS 'bios-256k.bin'\nDomain installation does not appear to have been successful.\nIf it was, you can restart your domain by running:\n virsh --connect qemu:///system start HostedEngineLocal\notherwise, please restart your installation.", "stderr_lines": ["/usr/lib/python2.7/site-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.21.1) or chardet (2.2.1) doesn't match a supported version!", " RequestsDependencyWarning)", "ERROR internal error: qemu unexpectedly closed the monitor: qemu: could not load PC BIOS 'bios-256k.bin'", "Domain installation does not appear to have been successful.", "If it was, you can restart your domain by running:", " virsh --connect qemu:///system start HostedEngineLocal", "otherwise, please restart your installation."], "stdout": "\nStarting install...", "stdout_lines": ["", "Starting install..."]} Seem that it's related to Python packages versions (urllib3 and chardet), but we wasn't sure about that. How could workaround this problem? Trying to install this libraries manually? We tried to found the same error over the Lists and Community, but we don't found some info about that. Thank for your help in advance. Regards!
