power9 machines are verry sluggish

[kraj]

when ppc9 machine is chosen (from Availabablity Zone) it can not boot. Tried ubuntu 19.04/18.04/Debian-9, Fedora-29 seems to boot ok. Debian like systems are stuck like below in console.
power8 boots ok on debian-like systems

@sitio-couto could you pair with @lcnzg today and check what is going on?

[sitio-couto]

@kraj, I was unable to reproduce the issue, all Debian derivatives seem to work.
Are you still having this issue? If so, is there any custom configuration you've used when creating the instance?

[kraj]

I just open ssh port and launch the largest instance nothing special.

@sitio-couto take a look at the placement, maybe one of the P9s is the issue.

I created 4-5 times and same issue all the time. Fedora 29 booted but was very very slow on p9
now I have provisioned a p8 VM and its chugging along ubuntu 19.04 well. I can build yocto
images

@sitio-couto take a look at the placement, maybe one of the P9s is the issue.

Both P9's are scheduling the Debian derivatives, although the load is unbalanced and launch times are a bit high (about 5-8 minutes).
I'm doing more tests to see if I can get an instance stuck during boot.

@kraj I was able to boot Ubuntu 18.04 and 19.04 on P9.

[kraj]

@rpsene ok. I have exhausted my compute quota for provisioning my p8 vm, for now, once I have done some build tests I will tear it down and re-install with ubuntu 19.04 on p9, How long should I wait for it to boot ?

[kraj]

OK I launched the instance and let it boot, next day I See the console shows the login prompt.
ssh also works as seen below. But the instance is so slow its quite visible. Perhaps thats another issue ?

ubuntu@yocto-power9:~$ cat /proc/cpuinfo

Hey kraj.
You're right, the power 9 machines are quite sluggish.
We're trying to pinpoint where's the problem, and as soon as we find out and fix it we'll let you know.
For now, it might be better to stick with the Power8 availability zone.
Apologies for the inconvenience.

@sitio-couto thanks for confirmation. No issues, I am happy to test it out. Let me know when you have it fixed. I started an update on the p9 VM about 6 hrs ago and it has not finished. Usually it should take less than 5 mins.
