<simpara>The disk cache mode. It can be either |
|
530 |
<userinput>default</userinput> to not pass any cache |
|
531 |
option to KVM, or one of the KVM cache modes: none |
|
532 |
(for direct I/O), writethrough (to use the host cache |
|
533 |
but report completion to the guest only when the host |
|
534 |
has commited the changes to disk) or writeback (to use |
|
535 |
the host cache and report completion as soon as the |
|
536 |
data is in the host cache). Note that there are |
|
537 |
special considerations for the cache mode depending on |
|
538 |
version of KVM used and disk type (always raw file |
|
539 |
under Ganeti), please refer to the KVM documentation |
|
540 |
for more details. |
