If you have suggestions, please send an email: https://www.tomvanbrienen.nl/contact/ Requirements OVZ7: CPU: at least 4 cores, a 64-bit processor is required for running 64-bit guest operating systems, • RAM: 4 GB or more, • HDD: 64 GB or more, • SSD (optional): at least 30 GB (at least 32 GB with /boot) When partitioning the disks, keep in mind that OpenVZ requires these partitions: • Boot: mount point /boot, 1 GB, boot partition with OpenVZ boot files, created on each HDD, • Root: mount point /, 12-24 GB, root partition with OpenVZ files, created on the HDD marked System, • Swap: paging partition with the swap file system, created on the HDD marked System. The size depends on RAM: • if RAM is below 2 GB, swap size should be twice the RAM, • if RAM is 2-8 GB, swap size should be equal to RAM, • if RAM is 8-64 GB, swap size should be half the RAM, otherwise swap size should be 32 GB • Data storage, mount point /vz, at least 30 GB, storage for virtual machines, containers, and OS and application templates, an LVM volume group that spans all HDDs marked Datastore. • In addition, either a 1 MB partition with the BIOS boot file system or a 200 MB partition with the EFI boot file system is required depending on your server configuration. Source requirements: https://docs.openvz.org/openvz_users_guide.pdf Lets start! Install OVZ7 on Hetzner Dedicated Servers. Step 1: Start installimage in Rescue Mode Step 2: Partition requirements (EXT4!): (/swap )- 50% (32GB = 16GB SWAP) (/boot) - 1GB (EXT4) (/) - 40GB (EXT4) (/vz) - All unused space for ex. (EXT4) Step 3: Image https://www.tomvanbrienen.nl/ovz7-hetzner/CentOS-70-64-minimal.tar # Info: The CentOS-70-64-minimal.tar is a clean installation tar from the original openvz-iso-7.0.7-361.iso. Factory/test repos are disabled. # URL: https://download.openvz.org/virtuozzo/releases/7.0/x86_64/iso/ Step 4: F2 & F10 to start the installation. Step 5: When the installation is finished, reboot and login with your root account and rescue password. Step 6: Important: cd /root Step 7: Download the networkconfigurator: wget https://www.tomvanbrienen.nl/ovz7-hetzner/networkconfig-ovz7.zip Step 8: Unzip the files: unzip networkconfig-ovz7.zip Step 9: Execute permissions: chmod +x network.sh Step 10: Run network.sh: ./network.sh Step 11: nano /etc/sysconfig/network-scripts/ifcfg-br0 and check the network configuration! Step 12: nano /etc/sysconfig/network-scripts/ifcfg-eth0 and check the network configuration! Step 13: Type: service network restart to apply your new config.
