Re: [lxc-users] Nova-lxd plugin installation

2018-10-22 Thread Martin Bobák 

Hi Alex,

UPDATE about the nova-lxd plugin issue:

Meanwhile, I fixed the issue in the following way. You are right about 
post-configuration of the plugin. However, DevStack installation of 
OpenStack requires the configuration of nova-compute not by the 
nova.conf file, but by the nova-cpu.conf file. Everything works fine 
after adding the lines (for the nova plugin configuration) into the file 
nova-cpu.conf.


Thank you very much for the help.

Best,
Martin.

Re: [lxc-users] Nova-lxd plugin installation

2018-10-07 Thread Martin Bobák 

Hi Brian,

I tried the suggestions on a host running Ubuntu 16.04.5 LST and 
OpenStack Queens devstack installation with LXD/LXC 3.0.1 (its storage 
backend was zfs). However, I wasn't able to recognize the nova-lxd 
driver with OpenStack. Thus, I tried to do "a configuration bruteforce" 
to see how does the current situation looks like. So we can see that 
LXD/LXC 2.O.X is best supported (you can create a virtual machine 
without a volume), however, it doesn't support GPUs for example -> 
LXD/LXC 3.X is a better choice.


On the other hand, a zfs storage backend causes lots of problems. I 
spent some time to fix it somehow, but I just swapped an error for 
another error (maybe I did something wrong, all in all, this is my 
experience with the zfs storage backend). Thus, I was curious, how the 
other configurations are supported and the results are summarized at the 
previous mail.


Now, I think I need a help with choosing the best configuration for 
LXD/LXC 3.X and how to run it properly. There are too many options and I 
would like to avoid playing with all of them.


Best,
Martin.

Re: [lxc-users] Nova-lxd plugin installation

2018-09-28 Thread Martin Bobák 

Hi Alex,

you are right, I installed stable/queens version (I haven't been sure 
about master branch compatibility) of nova-lxd via devstack using ZFS. 
Meanwhile, I tried to create a new storage for LXD with different names 
for LXD pool and ZFS pool, however, the problem was still there. But 
when I created "None" storage with a following line


sudo lxc storage create None_pool zfs zfs.pool_name=None

The problem was solved, and I moved to another error -> "Host 'ubuntu' 
is not mapped to any cell" (I will build OpenStack one again with the 
nova cells service enabled, and I will write about the results. As I 
wrote, I used local.conf from github repo. There isn't nova cell enabled),


Best,
Martin

Hi Martin

Okay, some progress which is great!

But, to help you further, a few more details:

 1. Which Linux OS are you using?



I'm using Ubuntu 16.04.5 LTS.


 1. Is the LXD snap installed? - if so, which version is it? "lxc
--version" will give the answer.



When I realised that the plugin is expecting LXD installed by apt (I 
came to this conclusion by 
https://github.com/openstack/nova-lxd/search?q=%2Fvar%2Flib%2F&unscoped_q=%2Fvar%2Flib%2F), 
I installed LXD/LXC 3.0.1 by "sudo apt install -t xenial-backports lxd lxc".


So is it possible to use a LXD snap installation also? Because, when I 
used it, the devstack installation script didn't recognize the LXD 
installation, and so "stack.sh" will install LXD version 2...



 1. Have you configured a storage pool for LXD?  (e.g. have you done
"sudo lxd init" and created a default storage pool).  What kind of
storage pool is it?  (e.g. dir, btrfs, zfs, etc.)



I am using a zfs storage pool. I configured it with "sudo lxd init". 
However, the changing of its name doesn't work properly (maybe LXD snap 
version fixed it) and so I created another zfs storage pool by LXC CLI, 
however, it wasn't successful, until its name wasn't None.



 1. It looks like your using master version of nova-lxd (i.e. via
devstack and the plugin)?  I think it's also going to use ZFS? If
so, there's a bug in nova-lxd (that I will fix in the not too
distant future) where unless the ZFS pool is the same string as
the LXD pool for it, then nova-lxd can't find the storage pool.

So, if you run the following commands:

lxc storage list
zpool list



default -> created by "lxd init" (also in previous cases)
stack -> created by "sudo lxc storage create stack zfs 
zfs.pool_name=stack_pool"
None_pool -> created by LXC CLI also, just to see whether it will work, 
or not.


 sudo lxc storage list

[DEFAULT]
compute_driver = nova_lxd.nova.virt.lxd.LXDDriver

[lxd]
allow_live_migration = True
pool = lxd

But the error is following (relevant parts from syslog --> it looks like 
lxd variables from the /etc/nova-compute.conf aren't delivered to the 
driver, or recognized by it, I tried to use different names for 
compute_driver e.g. lxd.LXDDriver, 
nova-lxd.nova.virt.lxd.(driver).LXDDriver -> however, it didn't help):

I'm one of the maintainers for nova-lxd, so hopefully can get you up and
running.

In order for nova-lxd to be configured in nova, the /etc/nova-compute.conf
needs to contain the lines:

[DEFAULT]
compute_driver = nova_lxd.nova.virt.lxd.LXDDriver

This little 'fact' is hidden away in the "nova-compute-lxd" debian package,
unfortunately.

You'll also need to configure an [lxd] section in nova.conf to control the
storage pool in LXD for containers to use when launching instances.

[lxd]
allow_live_migration = True
pool = {{ storage_pool }}

The storage pool will need to be set up separately in lxd.
--

However, an 'easy' way to test OpenStack with nova-lxd, is to use charms.
We have a number of bundles that work with Juju.  For example we have a
deployable bundle for xenial and queens at https://github.com/
openstack-charmers/openstack-bundles/tree/master/development/openstack-lxd-
xenial-queens which also has some (hopefully) useful instructions on how to
get it going.

Note the instructions say you have to use MaaS, but you should be able to
adjust using it to the hardware you are using.

As an alternative, the openstack-ansible project also supports nova-lxd,
but I don't have any experience with that.

Do come back if you have any further questions; do let me know how you get
on.

Best regards
Alex.

[lxc-users] Nova-lxd plugin installation

2018-09-16 Thread Martin Bobák 

Hi all,

what is the recommended way of nova-lxd plugin installation on a fresh 
xenial host running a pure OpenStack devstack (Queens) installation? I 
have tried to install the nova-lxd plugin by pip install, or allowing it 
during OpenStack devstack  installation, but each attempt lead to the 
same result. The plugin is either not recognized or the installation 
doesn't finish successfully. I went through the nova-lxd homepage as 
well as its github repo, but I wasn't able to solve the whole 
installation problem (e.g. I found out that the installation of the 
newest version of pylxd helps with installation of the plugin, however, 
the plugin isn't still recognized. So additional configuration is 
needed...).


Do you have any thoughts about it?

Best,
Martin.

[lxc-users] [nova-lxd plugin]: Installation problem on Ubuntu 16.04 with LXD 3.4

2018-08-30 Thread Martin Bobák 

Hi all,

what is a recommended way to install the nova-lxd plugin?

I deployed OpenStack Queens (and Pike out of curiosity) at Ubuntu 16.04 
(since Ubuntu 18.04 haven't been supported by Queens officially yet) 
with LXD 3.4 by devstack local.conf from 
https://github.com/openstack/nova-lxd/blob/master/devstack/local.conf.sample. 
I have found out two ways how to install the nova-lxd plugin:


1. *allowing the nova-lxd plugin during installation* (by including a
   following line enable_plugin nova-lxd
   https://git.openstack.org/openstack/nova-lxd into a devstack
   local.conf). However, this line causes a following compilation error:

   /ERROR:root:Error parsing TypeError: super() argument 1 must be
   type, not None//
   //    error in setup command: Error parsing
   /tmp/pip-build-Sksse4/pylxd/setup.cfg: TypeError: super() argument 1
   must be type, not None//
   //Command "python setup.py egg_info" failed with error code 1 in
   /tmp/pip-build-Sksse4/pylxd///
   /
2. *through cloud-archive repo.* Since, I am not able to see nova-lxd
   package directly (I tried many repos, but each of attempts ended up
   with the same result). Thus, I installed following packages:
   nova-compute-lxd, python-nova-lxd, and python-nova.lxd. However,
   this causes two types of errors:
 * OpenStack Pike -> series of serious errors in the *horizon
   module*. The web interface isn't able to connect to the other
   modules properly. I got following errors:/

   Error: Unable to retrieve the extensions.
   /
   /Error: //Unable to retrieve the extensions./
   //
   /Error: //Unable to retrieve the extensions./
   //
   /Error: //Unable to retrieve the extensions./
   //
   /Error: //Unable to retrieve the extensions./
   //
   /Error: //Unable to retrieve the flavours./
   //
   /Error: //Unable to retrieve the limits./
   //
   /Error: //Unable to retrieve the availability zones./
   //
   /Error: //Unable to retrieve the keypairs./
   //
   /Error: //Unable to retrieve the extensions./
   //
   /////Error:
   //Unable to retrieve instances.
   .

   /
 *
   OpenStack Queens -> In another case the *keystone module* was
   undiscovered:/

   Failed to discover available identity versions when contacting
   http://127.0.0.1/identity/v3. Attempting to parse version from
   URL.//
   Could not determine a suitable URL for the plugin/

Also installations from devstack are pointing on a bad repo branch by 
default (Pika installation on Octa repo, Queens installation on Pika repo).


Thank you for any help,
Martin
