Thanks very much for Kaustav Majumder! After reading your links, I would like to ask, which step of installing ovirt-engine is followed by the operation of “Installing VDSM from rpm” ?

Thanks very much for Kaustav Majumder! Now my environment is : The version of ovirt-engine is 4.3.5.5 The version of ovirt-node is 4.3.5 Question1 : Is this step correct: 1. Server1 installs ovirt-engine 2. Installing VDSM from rpm on ovirt-engine （ You tell me the link : https://www.ovirt.org/develop/developer-guide/vdsm/installing-vdsm-from-rpm.... ） 3. Install ovirt-node on Server2 4. Add the ovirt-node to the ovirt-engine Question 2： Can I install ovirt-engine and ovirt-node on a virtual machine? Still have to be installed on a physical machine?

Thanks very much for Kaustav Majumder! Follow the steps you taught me： 1. Server1 install ovirt-engine 2. Server2 install ovirt-node 3. Set bridge network using the link on ovirt-node ( https://www.ovirt.org/develop/developer-guide/vdsm/installing-vdsm-from-r... ) 4. Add ovirt-node to ovirt-engine Server 1 is a Dell R740 Server. Server 2 is a virtual machine. The OS of Server1 is 4.3.5.5-1.el7 The OS of Server2 is ovirt-node-ng-installer-4.3.5-2019073010.el7.iso In Step 3: When I use command "yum install -y vdsm vdsm-cli" on ovirt-node. It show : " http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/epel-7/no...: [Errno 14] HTTPS Error 404 - Not Found Trying other mirror. Excluding 46 updates due to versionlock (use "yum versionlock status" to show them) Nothing to do " Then I check the version of vdsm : [root@ovirt-node1 ~]# rpm -qa|grep vdsm vdsm-http-4.30.24-1.el7.noarch vdsm-hook-fcoe-4.30.24-1.el7.noarch vdsm-yajsonrpc-4.30.24-1.el7.noarch vdsm-python-4.30.24-1.el7.noarch vdsm-hook-vmfex-dev-4.30.24-1.el7.noarch vdsm-hook-ethtool-options-4.30.24-1.el7.noarch vdsm-api-4.30.24-1.el7.noarch vdsm-common-4.30.24-1.el7.noarch vdsm-network-4.30.24-1.el7.x86_64 vdsm-jsonrpc-4.30.24-1.el7.noarch vdsm-hook-vhostmd-4.30.24-1.el7.noarch vdsm-hook-openstacknet-4.30.24-1.el7.noarch vdsm-4.30.24-1.el7.x86_64 vdsm-gluster-4.30.24-1.el7.x86_64 vdsm-client-4.30.24-1.el7.noarch Then I add ovirt-node1 to ovirt-engine: It report: Host ovirt-node1 installation failed. Failed to configure management network on the host. VDSM ovirt-node1 command Get Host Capabilities failed: Internal JSON-RPC error: {'reason': "invalid argument: KVM is not supported by '/usr/libexec/qemu-kvm' on this host"} So my question is what's the problem ? How can I slove this problem ? Thank you very much!
