Re: [Openstack] XenServer 6.5 or KVM

[Bob Ball]

Hi Leandro,

It is true that the majority of development work, and the majority of 
deployments, happen with the libvirt+KVM combination however there are some 
major deployments that use XenServer highly effectively.

Regarding Neutron support, yes there are a number of known areas where we need 
more development effort to fully support this with XenServer, and these are 
ongoing.  If you're set on deploying Neutron today then you may be best served 
by looking at other hypervisors.

XenServer works easily with nova-network and, as Rackspace has proven possible, 
can also work with Neutron (just not as easily!).  If there are specific docs 
that you've identified that are out of date please let me know and we can have 
a look.

Thanks,

Bob

What do you guys think about that?

Hi Sam,
very well & easy to read blog post. Did you consider trying out Fuel
plugable framework for enabling SRIOV?

Just curios if you considered it and saw any gaps, I just want to know
about those.

Re: [Openstack] XenServer 6.5 or KVM

[Mārtiņš Jakubovičs]

Hello Leandro,

From my experience OpenStack + XenServer is really difficult to build, 
but it *work*. Newest features like neutron, advanced cinder drivers, 
XenServer pool's, etc is not working well. At least with XenServer 6.2 
and Icehouse release. If you know both technologies and don't know which 
to choose then use KVM.
If you want to use XenServer then community member Bob Ball 
(bob.b...@citrix.com) can help you more with this.


Best regards,
Martins

[Openstack] Python API for Dynamic Large Objects in Swift

[Vincenzo Pii]

To upload a Dynamic Large Object with the Swift CLI one can just do

swift upload newcont -S 1048576000 large_object

but, is there any equivalent in the swift python APIs (swiftclient module
from https://github.com/openstack/python-swiftclient)?

The content_length parameter of put_object will just truncate the content...

Thanks,
Vincenzo.

Re: [Openstack] XenServer 6.5 or KVM

[Leandro Mendes]

Thank you guys.

One last question: This 3 node setup is just a proof of concept of a bigger
architecture (with around 30 nodes). I personally would prefer use KVM, so
we can use Kilo and Neutron, but for some political reasons, we are really
pushed to use XenServer (no problem about XS itself, I think it is great),
but we don't have enough time and "hands" to make it work.

Thinking about it,i would ask (maybe *Bob* will give me the best answer)
what should be the best choise for use Openstack with XenServer regarding
their versions?
Maybe an older XCP with Juno or Icehouse?

And what about VMWare as it is as XenServer in *Group B*?

Thank you again.

Re: [Openstack] XenServer 6.5 or KVM

[Bob Ball]

I would always recommend the latest version of XenServer and of OpenStack.  In 
particular there were a couple of fixes for race conditions that have gone into 
Kilo, so I would recommend using that version.

XenServer 6.5 with SP1 is the newest XenServer and has a number of performance 
and scalability enhancements that, even if you are happy with the feature set 
in earlier versions of XenServer, mean that I would recommend it.
As a minimum, XenServer 6.2 would also work.

Thanks,

Bob

Re: [Openstack] XenServer 6.5 or KVM

[Ivan Derbenev]

We had a small deployment (2 nodes) of OS Juno+XS6.5 and after I understood how 
it should work with Xen everything worked great.
Still, we had to move for KVM because XS with local storage lacked support of 
dynamic volumes via Cinder.

If you plan to use shared storage for VMs, XS is a great choice. It’s MUCH 
easier to maintain then KVM, especially for a newbie in such technologies

Re: [Openstack] [Packstack] Install without Internet

Again I have done this in several productions deployments so not an issue.

Hi,

We are trying to install Openstack Packstack on a machine that only has access 
to the local Intranet.  While it may be possible to proxy it through another 
machine it would be ideal if we could just host all the files needed on an 
internal repo and install from there.

Is there a method for doing this?

Thanks,

Michael.

This interface should be DOWN, since the vif-bridge script is responsible
to configure it and set it UP. And I don't see what could change its state.

Could you run the following command after you tried to start a guest?

$ xenstore-ls /local/domain/0/libxl
disable_udev = "1"

We should at least have disable_udev in the output.

I've tried to follow the guide, and install OpenStack on Ubuntu 14.04 but I
can not reproduce this. I've stop after installing neutron, and try to
start a guest. I may have miss something.


Otherwise, to work arround this bug we could modify the script to set down
the interface before trying to rename it:
In /etc/xen/scripts/vif-common.sh, search the function rename_vif() and add
in the begining this:
  ip link set "$dev" down
And don't forget to remove the "exit 0" in /etc/xen/scripts/vif-bridge that
we've added earlier.

[Openstack] Storing Heat Templates on Glance Artifact Repo on Kilo

[Martinx - ジェームズ]

Guys,

 I have a bunch of Heat Templates and I would like to know if it is
possible to store those templates on Glance.

 Is it possible?

 If yes, how?

 I'm using OpenStack Kilo on top of Ubuntu Trusty (using Ubuntu Cloud
Archive).

Thanks!
Thiago

Yes, I can confirm the output: 
root@hp3:~# xenstore-ls /local/domain/0/libxl
disable_udev = "1"

Okay thanks, I think it's more likely that I may have missed something
since it doesn't work here :)

I removed the exit line and added the ip link command to the rename_vif()
function, however, I then receive the same initial error and the instance
fails to boot:

libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus: 
/etc/xen/scripts/vif-bridge online [-1] exited with error status 1
libxl: error: libxl_device.c:1085:device_hotplug_child_death_cb: script: ip

w=0x7f37c800a050: deregister unregistered
libxl: error: libxl_create.c:1226:domcreate_attach_vtpms: unable to add nic 
devices

Thanks again for helping work through this,
Geoffrey

Re: [Openstack] Geo-replicated cluster...

[Clay Gerrard]

Neither container-sync nor global replication support that.

I'm not sure if quiesce would be a good fit for the project honestly since
you have to pause writes with an unbounded window and coordinating that
would defeat some of swift's goals scalability and availability.

Honestly, something about your phrasing makes me think somehow that there's
an idea maybe that replication or container-sync is somehow rate limited?
It's asynchronous in sense it's not in the data-path - but it's always
going as fast as it can in the background.  Better traffic shaping in
replication is a feature we've looked at - I could imagine some tooling to
make that more dynamic - what's there now is pretty course.  Rate limiting
in the container-sync daemon could be very useful - and has a might better
chance of being able to "report" it's progress via the API than partition
replication.  I think there's some ongoing work on this.
