| − | + | Debian 9 installer formats Ext4 with new features (64bit metadata_csum) and this is incompatible with OpenVZ6 kernel (initrd cannot mount root). Then it's necessary to boot without requiring the mount of this advanced format. Options: | |
| − | + | * Root volume (/) as Ext3 and /var/lib/vz separated in an Ext4 | |
| − | + | * Install Debian 8 (will format without "64bit") and upgrade to Debian 9 | |
| − | + | * Install Debian 9 to a previously formatted Ext4 without "64bit". | |
