DISK_%N_BACKEND_TYPE |
| 92 | 92 |
How files are visible on the node side. This can be either |
| 93 | 93 |
``block`` (when using block devices) or ``file:type``, where |
| 94 |
``type`` is either ``loop`` or ``blktap`` depending on how the
|
|
| 95 |
hypervisor will be configured. Note that not all backend types |
|
| 96 |
apply to all hypervisors.
|
|
| 94 |
``type`` is either ``loop``, ``blktap`` or ``blktap2``, depending on how the
|
|
| 95 |
hypervisor will be configured. Note that not all backend types apply to all
|
|
| 96 |
hypervisors. |
|

NIC_COUNT |
| 99 | 99 |
Similar to the ``DISK_COUNT``, this represents the number of NICs |

better performance. Especially if you use a network file system |
| 845 | 845 |
(e.g. NFS) to store your instances this is the recommended choice. |
| 846 | 846 |
|
| 847 |
blktap2 |
|
| 848 |
Analogous to the blktap driver, but used by newer versions of Xen. |
|
| 849 |
|
|
| 847 | 850 |
If ``--ignore-ipolicy`` is given any instance policy violations occuring |
| 848 | 851 |
during this operation are ignored. |
