Installing and Deploying oVirt-host

To install and deploy oVirt-host on compute nodes, you need to modify the /usr/libexec/vdsm/hooks/before_vm_start/50_hostedengine file.

1. Install oVirt-host.

   1	yum install -y ovirt-host glibc ovirt-hosted-engine-setup

2. Manually load the Open vSwitch kernel driver.

   1	modprobe openvswitch

   

   If the OS is restarted, reload is required.

3. Upgrade OpenSSH and sudo.
   If the OpenSSH and sudo versions are too early, the oVirt service cannot be started.

   1	yum update -y openssh sudo

4. Modify the /usr/libexec/vdsm/hooks/before_vm_start/50_hostedengine file.
   1. Open the file.

      1	vi /usr/libexec/vdsm/hooks/before_vm_start/50_hostedengine

   2. Press i to enter the insert mode and change python3 in the file header to /usr/bin/python3.

      

   3. Press Esc to exit the insert mode. Type :wq! and press Enter to save the file and exit.
