viclarson | is anybody here? | 14:52 |
viclarson | hello | 14:52 |
viclarson | im on duty today | 14:53 |
adreznec | Hi viclarson, what can we help with? | 14:53 |
viclarson | wow | 14:53 |
viclarson | could you plz explain how to implemented integration with novnc-proxy in powervm-nova-compute-driver | 14:54 |
adreznec | Are you asking how to set the function up? novnc support is already integrated into the PowerVM Nova compute driver | 14:57 |
*** viclarson has quit IRC | 15:01 | |
*** tblakes has joined #openstack-powervm | 15:02 | |
*** efried has joined #openstack-powervm | 15:04 | |
efried | AlexeyAbashkin: resize is already supported in the out-of-tree driver. | 15:05 |
*** kriskend has joined #openstack-powervm | 15:06 | |
AlexeyAbashkin | in our deployment it does only shutdown VM and that's it. | 15:06 |
*** viclarson has joined #openstack-powervm | 15:07 | |
AlexeyAbashkin | in code I've seen "not implemented". give me time I'll find this part | 15:07 |
viclarson | we have consoleauth and novnc-proxy at controlplane and expect vnc at compute | 15:12 |
viclarson | in fact vnc listen at localhost | 15:13 |
efried | AlexeyAbashkin: Hm, perhaps you're right. I was looking at resize code just the other day - but it may have been resize as part of some other operation. | 15:13 |
viclarson | and external_ip:59xx response to requests for novnc-proxy 400 (malformed request) | 15:14 |
viclarson | is it proxy? | 15:14 |
AlexeyAbashkin | and please help viclarson with noNVC. we work on the same cloud | 15:15 |
efried | AlexeyAbashkin: Ah, I remember now. We have resize support. Apparently resize is implemented via the migration code. | 15:15 |
viclarson | not implemented for ssp driver | 15:16 |
AlexeyAbashkin | yes. we place VMs on SSP | 15:16 |
adreznec | viclarson: Hmm, that's odd. Are you seeing the compute driver receiving the vnc proxy request in the logs? What does your compute node [vnc] config section look like"? | 15:17 |
efried | Sorry, I'm not quite following. | 15:17 |
*** kylek3h has joined #openstack-powervm | 15:17 | |
adreznec | Also what version of openstack is this? mitaka? newton? | 15:17 |
AlexeyAbashkin | this is mitaka | 15:18 |
viclarson | all neccessary records are in config | 15:18 |
viclarson | and we expect novnc-proxy at controlplane | 15:18 |
AlexeyAbashkin | viclarson can you paste config here? | 15:18 |
viclarson | no | 15:18 |
viclarson | i cant | 15:18 |
adreznec | Hmm ok | 15:19 |
viclarson | have ability to start linuxvnc service to listen 0.0.0.0 and switch off novnc at compute | 15:20 |
viclarson | wo cropping code? | 15:20 |
viclarson | without cropping code? | 15:20 |
adreznec | We've definitely tested vncproxy working with mitaka... I can paste out an example section of config that I have working | 15:20 |
adreznec | Going to pull thorst in here as well, he's the one who's worked most on our VNC code | 15:21 |
adreznec | This is an example compute-side nova.conf vnc section I'm using: http://paste.openstack.org/show/594572/ | 15:24 |
viclarson | the same config without keymap and enabled keys | 15:26 |
adreznec | Does enabled default to true in Nova's vnc conf? If not that could be an issue | 15:31 |
*** Nil_ has joined #openstack-powervm | 15:32 | |
viclarson | i think it's default | 15:32 |
viclarson | we have netstat -tnlp | 15:33 |
viclarson | 127.0.0.1 5903 linuxvnc | 15:33 |
viclarson | 10.123.3.166 5903 pyhton | 15:33 |

viclarson | what is it at 10.123.3.166:5903? | 15:35 |
viclarson | and how to switch it out? | 15:36 |

*** Sujeet_ has joined #openstack-powervm | 15:41 | |
adreznec | viclarson: 10.123.3.166 isn't the IP address of the Novalink host? | 15:41 |
viclarson | yes it ip address of novalink host | 15:42 |
adreznec | Also pinged a couple of people more familiar our vnc code to get more feedback here | 15:42 |
viclarson | but i expect RFB response at it address | 15:42 |
viclarson | but i expect RFB response at this address | 15:43 |
adreznec | Yeah, you shouldn't be getting a 400 back | 15:43 |
thorst | hey - sorry, I've been in meetings for a few hours | 15:43 |
thorst | I'm reading back this thread. | 15:43 |
viclarson | actually i dont need 400 code) | 15:44 |
thorst | viclarson: do you know what level your pypowervm is? | 15:44 |
adreznec | (if not you can do "dpkg -l | grep pypowervm") | 15:44 |
thorst | we had several changes in the VNC stuff in newton that made it more stable...really it was in the 1.0.0.4 version of pypowervm | 15:44 |
viclarson | 1.0.0.3.2 | 15:45 |
viclarson | we have mitaka | 15:45 |
adreznec | That should be fine with Mitaka... | 15:45 |
thorst | adreznec: right...but there were some enhancements to VNC in the 1.0.0.4 version of novalink (which includes pypowervm's 1.0.0.4) | 15:45 |
thorst | but the basic idea is that pypowervm presents a port / IP for the VNC and sends it back to the nova-api | 15:46 |
thorst | then nova-api sends that to the noVNC server | 15:46 |
thorst | and the noVNC server connects to that | 15:46 |
thorst | so you want to make sure that the noVNC server has IP connectivity to the NovaLink host. | 15:47 |
viclarson | can i expect vnc at external address in new version? | 15:47 |
thorst | no, the VNC address is set by your noVNC server | 15:47 |
thorst | and which address the driver binds it to is set by your nova.conf | 15:47 |
thorst | let me look up the variable. | 15:47 |
viclarson | i mean vnc protocol | 15:47 |
adreznec | vncserver_proxyclient_address? | 15:47 |
viclarson | telnet 10.123.3.166 5903 | 15:48 |
thorst | https://github.com/openstack/nova/blob/stable/mitaka/nova/conf/vnc.py | 15:48 |
thorst | why are you 'telnet'ing to it? | 15:48 |
viclarson | i expect RFB response | 15:48 |
thorst | no, you won't get that | 15:48 |
viclarson | why? | 15:48 |
thorst | because we send a header so that random VNC's can't just connect to it | 15:49 |
thorst | that is specific to the OpenStack code...its a minor thing we do to make sure only OpenStack clients can VNC into it | 15:49 |
thorst | if you want that removed...let me get the nova-powervm code to remove | 15:49 |
thorst | sec... | 15:49 |
viclarson | is it powervm specific? | 15:49 |
thorst | Xen does something similar too | 15:50 |
thorst | it's specific to how we implemented the OpenStack PowerVM driver (specifically how I choose to implement it) | 15:50 |
thorst | because I don't want random VNC clients connecting in to an open channel - its a security measure. | 15:50 |
thorst | https://github.com/openstack/nova-powervm/blob/stable/mitaka/nova_powervm/virt/powervm/driver.py#L1779 | 15:51 |
thorst | if you want to get RFB back, that part that says 'vnc_path=lpar_uuid' you just remove. But then also remove the internal_access_path on line 1784 | 15:51 |
viclarson | and vanilla novnc-proxy d be available to connect to this port without specific setting? | 15:52 |
viclarson | ty for help | 15:52 |
thorst | yeah, it should 'just work' with vanilla openstack (it does with devstack) | 15:52 |
thorst | OSA works too, but we (specifically adreznec) had to put support into OSA to enable VNC...but that wasn't powervm specific I don't think | 15:52 |
efried | thorst adreznec - https://review.openstack.org/#/c/413736/ ? | 16:00 |
*** Nil_ has quit IRC | 16:00 | |
*** Sujeet_ has quit IRC | 16:02 | |
adreznec | thorst: Nope, nothing powervm specific there | 16:03 |
thorst | heh...I'll review that now | 16:07 |
thorst | but wait for adreznec's +2 as well | 16:07 |
thorst | did we ever get your e-mail efried | 16:07 |
adreznec | I never saw it | 16:07 |
adreznec | I was thinking - was it because he did [openstack] instead of [openstack-dev]? | 16:08 |
thorst | ooo, yah | 16:08 |
thorst | probably | 16:08 |

thorst | adreznec: I was looking through some of the errors in the CInow | 17:11 |
thorst | the failures seem to be downloading that cirros image | 17:11 |
thorst | would your additional server help with that download? | 17:11 |
adreznec | Depends on why it's failing, I guess | 17:12 |
adreznec | If it's a DNS timeout or something yes | 17:12 |
adreznec | Otherwise not as thing stand now | 17:13 |
thorst | download timeout | 17:13 |
thorst | not DNS | 17:13 |
adreznec | Right, but why is it timing out on the download | 17:13 |
adreznec | cirros site isn't responding in time? | 17:13 |
adreznec | internal download length timeout? | 17:14 |
*** kairo_ has joined #openstack-powervm | 17:15 | |

thorst | see that error...that's the consistent one... | 17:21 |
thorst | looks like its defined by CONF.image.http_image | 17:23 |
thorst | so yeah? Lets put that image on your remote server... | 17:24 |
