Open Stack

Hi,

According to the help text, “—min-count <number>” boot at least <number> servers (limited by quota):


--min-count <number>          Boot at least <number> servers (limited by

                                quota).


I used devstack to deploy OpenStack (version Kilo) in a multi-node setup:

1 Controller/Network + 2 Compute nodes


I update the tenant demo default quota “instances" and “cores" from ’10’ and ’20’ to ‘100’ and ‘200’:


localadmin at qa4:~/devstack$ nova quota-show --tenant 62fe9a8a2d58407d8aee860095f11550 --user eacb7822ccf545eab9398b332829b476

+-----------------------------+-------+

| Quota                       | Limit |

+-----------------------------+-------+

| instances                   | 100   |   <<<<<

| cores                       | 200   |   <<<<<

| ram                         | 51200 |

| floating_ips                | 10    |

| fixed_ips                   | -1    |

| metadata_items              | 128   |

| injected_files              | 5     |

| injected_file_content_bytes | 10240 |

| injected_file_path_bytes    | 255   |

| key_pairs                   | 100   |

| security_groups             | 10    |

| security_group_rules        | 20    |

| server_groups               | 10    |

| server_group_members        | 10    |

+-----------------------------+-------+

When I boot 50 VMs using “—min-count 50”, only 48 VMs come up.


localadmin at qa4:~/devstack$ nova boot --image cirros-0.3.2-x86_64-uec --flavor 1 --nic net-id=5b464333-bad0-4fc1-a2f0-310c47b77a17 --min-count 50 vm-

There is no error in logs; and it happens consistently.

I also tried “—min-count 60” and only 48 VMs com up.

In Horizon, left pane “Admin” -> “System” -> “Hypervisors”, it shows both Compute hosts, each with 32 total VCPUs for a grand total of 64, but only 48 used.

Is this normal behavior or is there any other setting to change in order to use all 64 VCPUs?

Thanks,
Danny
