Note that the <replaceable>clustername</replaceable> is not |
| 209 | 213 |
any random name. It has to be resolvable to an IP address |
| 210 | 214 |
using DNS, and it is best if you give the fully-qualified |
| 211 |
domain name. |
|
| 215 |
domain name. Also it is advisable to reserve a per-cluster |
|
| 216 |
unique name, and not try to reuse one of the nodes' names. |

Note that for Ganeti it doesn't matter if the secondary |
| 229 |
|
|
| 230 | 234 |
network is actually a separate physical network, or is done |
| 231 | 235 |
using tunneling, etc. For performance reasons, it's |
| 232 | 236 |
recommended to use a separate network, of course. |

The <option>-b</option> option specifies the default bridge |
| 237 | 241 |
for instances. |

The <option>-t</option> allows to set the hypervisor type of |
| 241 | 246 |
the cluster. Available hypervisor types are: xen-3.0, fake and |
| ... | ... | |
| 247 | 252 |
<filename>/srv/ganeti/iso/hvm-install.iso</filename> because |
| 248 | 253 |
instances created by the experimental HVM support require them. |

The <option>-g</option> option will let you specify a volume group |
|
| 258 |
different than xenvg for ganeti to use when creating instance disks. |
|
| 259 |
This volume group must have the same name on all nodes. |

The <option>--master-netdev</option> option is useful for specifying a |
|
| 264 |
different interface on which the master will activate its IP address. |
|
| 265 |
It's important that all nodes have this interface because you'll need |
|
| 266 |
it for a master failover. |

The <option>-m</option> option will let you specify a three byte prefix |
|
| 271 |
under which the virtual MAC addresses of your instances will be |
|
| 272 |
generated. The prefix must be specified in the format XX:XX:XX and the |
|
| 273 |
default is aa:00:00. |
