   9 {pve} ships as a set of Debian packages, so you can simply install it
  10 on top of a normal Debian installation, or download the installation
  11 CD-ROM and use that to install {pve} on your hardware.
  12
  13 Installing on top of an existing Debian installation looks easy, but
  14 it presumes that you have correctly installed the base system, and you
  15 know how you want to configure and use the local storage. Network
  16 configuration is also completely up to you.
  17
  18 In general, this is not trivial, especially when you use LVM or
  19 ZFS. This is why we provide an installation CD-ROM for {pve}. That
  20 installer just ask you a few questions, then partitions the local
  21 disk(s), installs all required packages and configures the system
  22 including a basic network setup. You can get a fully functional system
  23 within a few minutes, including the following:
  24
  25 * Complete operating system (Debian Linux, 64-bit)
  26 * Partition the hard drive with ext4 (alternative ext3 or xfs) or ZFS
  27 * {pve} Kernel with LXC and KVM support
  28 * Complete toolset
  29 * Web based management interface

  38 Using the {pve} Installation CD-ROM
  39 -----------------------------------
  40
  41 This is the preferred and recommended installation method.
  42
  43 NOTE: By default, the complete server is used and all existing data is
  44 removed.
  45
  46 Please insert the installation CD-ROM, then boot from that
  47 drive. Immediately afterwards you can choose the following menu
  48 options:
  49
  50 Install Proxmox VE::
  51
  52 Start normal installation.
  53
  54 Install Proxmox VE (Debug mode)::
  55
  56 Start installation in debug mode. It opens a shell console at several
  57 installation steps, so that you can debug things if something goes
  58 wrong. Please press `CTRL-D` to exit those debug consoles and continue
  59 installation. This option is mostly for developers and not meant for
  60 general use.
  61
  62 Rescue Boot::
  63
  64 This option allows you to boot an existing installation. It searches
  65 all attached hard disks and, if it finds an existing installation,
  66 boots directly into that disk using the existing Linux kernel. This
  67 can be useful if there are problems with the boot block (grub), or the
  68 BIOS is unable to read the boot block from the disk.
  69
  70 Test Memory::
  71
  72 Runs `memtest86+`. This is useful to check if your memory is
  73 functional and error free.
  74
  75 You normally select *Install Proxmox VE* to start the installation.
  76 After that you get prompted to select the target hard disk(s). The
  77 `Options` button lets you select the target file system, which
  78 defaults to `ext4`. The installer uses LVM if you select `ext3`,
  79 `ext4` or `xfs` as file system, and offers additional option to
  80 restrict LVM space (see <<advanced_lvm_options,below>>)
  81
  82 If you have more than one disk, you can also use ZFS as file system.
  83 ZFS supports several software RAID levels, so this is specially useful
  84 if you do not have a hardware RAID controller. The `Options` button
  85 lets you select the ZFS RAID level, and you can choose disks there.
  86
  87 The next pages just ask for basic configuration options like time
  88 zone and keyboard layout. You also need to specify your email address
  89 and superuser (root) password (must have at least 5 characters).
  90
  91 The last step is the network configuration. Please note that you can
  92 use either IPv4 or IPv6 here, but not both. If you want to configure a
  93 dual stack node, you can easily do that after installation.
  94
  95 If you press `Next` now, installation starts to format disks, and
  96 copies packages to the target. Please wait until that is finished,
  97 then reboot the server.
  98
  99 Further configuration is done via the Proxmox web interface. Just
 100 point your browser to the IP address given during installation
 101 (https://youripaddress:8006).
 102
 103 NOTE: Default login is "root" (realm 'PAM') and the root password is
 104 defined during the installation process.

 108 Advanced LVM Configuration Options
 109 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 110
 111 The installer creates a Volume Group (VG) called `pve`, and additional
 112 Logical Volumes (LVs) called `root`, `data` and `swap`. The size of
 113 those volumes can be controlled with:
 114
 115 `hdsize`::
 116
 117 Defines the total HD size to be used. This way you can save free
 118 space on the HD for further partitioning (i.e. for an additional PV
 119 and VG on the same hard disk that can be used for LVM storage).
 120
 121 `swapsize`::
 122
 123 To define the size of the `swap` volume. Default is the same size as
 124 installed RAM, with 4GB minimum and `hdsize/8` as maximum.
 125
 126 `maxroot`::
 127
 128 The `root` volume size. The `root` volume stores the whole operation
 129 system.
 130
 131 `maxvz`::
 132
 133 Define the size of the `data` volume.
 134
 135 `minfree`::
 136
 137 To define the amount of free space left in LVM volume group `pve`.
 138 16GB is the default if storage available > 128GB, `hdsize/8` otherwise.
 139 +
 140 NOTE: LVM requires free space in the VG for snapshot creation (not
 141 required for lvmthin snapshots).

 144 ZFS Performance Tips
 145 ~~~~~~~~~~~~~~~~~~~~
 146
 147 ZFS uses a lot of memory, so it is best to add additional RAM if you
 148 want to use ZFS. A good calculation is 4GB plus 1GB RAM for each TB
 149 RAW disk space.
 150
 151 ZFS also provides the feature to use a fast SSD drive as write cache. The
 152 write cache is called the ZFS Intent Log (ZIL). You can add that after
 153 installation using the following command:
 154
 155  zpool add <pool-name> log </dev/path_to_fast_ssd>

 170 Install {pve} on Debian
 171 -----------------------
 172
 173 {pve} ships as a set of Debian packages, so you can simply install it
 174 on top of a normal Debian installation. After configuring the
 175 repositories, you need to run:
 176
 177 [source,bash]
 178 ----
 179 apt-get update
 180 apt-get install proxmox-ve
 181 ----
