Your instance types, networking environment, hypervisor type and version |
722 | 722 |
may all affect what kind of parameters should be used on your cluster. |

For example kvm instances are by default configured to use a host |
|
725 |
kernel, and to be reached via serial console, which works nice for Linux |
|
726 |
paravirtualized instances. If you want fully virtualized instances you |
|
727 |
may want to handle their kernel inside the instance, and to use VNC. |

Instances are by default configured to use a host kernel, and to be |

Some versions of KVM have a bug that will make an instance hang when |
|
732 |
configured to use the serial console (which is the default) unless a |
|
733 |
connection is made to it within about 2 seconds of the instance's |
|
734 |
startup. For such case it's recommended to disable the |
|
735 |
``serial_console`` option. |
