889962 - Loan talos-linux64-ix-001 to dminor, ctalbert & gbrown

Status: RESOLVED FIXED

(Infrastructure & Operations Graveyard :: CIDuty, task)

Description

[John O'Duinn [:joduinn] (please use "needinfo?" flag)]

as part of figuring out how to setup android-x86 testing on emulator-on-ix-hardware, ctalbert needs an ubuntu64 ix node to experiment on and evaluate setup instructions. With any luck those instructions can be turned into puppet scripts.

(From previous experiments, running emulators-on-aws does not seem to work, hence the hardware.)

Comment 1

[cmtalbert]

Also, gbrown and dminor will probably also need access to this box so that they can see the machine and help get things stood up quickly.

Comment 2

[[e-mail] (:bhearsum)]

Does this have to be hardware? AFAIK, we run the same tests on hardware and aws ubuntu machines.

Comment 3

[cmtalbert]

Yes, it has to be hardware.

Comment 4

[cmtalbert]

The x86 emulators do not work in AWS. We could never get them to boot there due to the way the x86 emulators re-use the underlying hardware.

Argh, got midaired last night! I set aside  talos-linux64-ix-001.test.releng.scl3.mozilla.com for this. Clint, I believe I gave you the password over IRC last night?

Yes you did, and I have verified that I can access it - thanks!

[Justin Wood (:Callek)]

clint, please reassign to nobody@ when you're done with this.

Comment 8

[Geoff Brown [:gbrown]]

Did someone change the password on this loaner? I cannot ssh into it now; after entering the password, I get "Permission denied, please try again.". 

It was fine this morning.

Comment 9

[Armen [:armenzg]]

I added gbrown's pub key to the authorized_keys.

Comment 10

[Armen [:armenzg]]

I believe we're done (or close to done) with this host.
When ready to return simply close the bug, we will re-image it and put it back into the pool.

Comment 11

[Geoff Brown [:gbrown]]

I will likely keep using it for another week or two -- it has been super-useful!

Comment 12

[Justin Wood (:Callek)]

gbrown, dan, are you still using this?

Comment 13

[Dan Minor [:dminor]]

I am not.

Comment 14

[Geoff Brown [:gbrown]]

I am still using it. Always hoping to wrap this work up and move on soon....

Comment 15

[Geoff Brown [:gbrown]]

This loan has been very useful and I am still finding uses for it.

But it suddenly started giving me trouble, starting between Jan 13 23:32 and Jan 14 00:30. I can no longer run the emulator; it complains

   SDL init failure, reason is: No available video device

stackoverflow articles suggested I check my DISPLAY env var. I use DISPLAY=:0.0, and that hasn't changed for months.

I tried rebooting -- no change.

:Callek kindly investigated today but could not find the cause.

Ben -- Could you have a look as well? If necessary, I don't mind if we re-image (I have everything I need backed up now).

It seems to work fine for me. I logged in as cltbld, ran /home/cltbld/gbrown/runset1, and found this in ps:

I double checked by logging in with vnc (need to run 'x11vnc' first) and saw the emulator running.

Can you try again?

Comment 17

[Geoff Brown [:gbrown]]

Confirmed -- it is working normally again. I wonder what happened?

Thanks!

This happened again. I noticed that there was no X server running. Simply running X from an ssh session allowed the emulator to start.

Comment 19

[John Hopkins (:jhopkins)]

Just checking in - is this loaner still needed?

Comment 20

[Geoff Brown [:gbrown]]

Yes, I'm afraid I keep finding new uses for it! Hope that's okay...

Comment 21

[Armen [:armenzg]]

:gbrown, do you still need this machine?

Comment 22

[Geoff Brown [:gbrown]]

No, I do not need it any more. All done - thanks.
