[openstack-community] [neutron] Adding support for elliptic curve in DH groups for key agreement protocol
by Matúš Brandys 19 Apr '21

19 Apr '21

Hi everyone, I was looking at neutron VPN implementation and found out that the current neutron implementation supports only creating VPN using DH up to group 15. For example, strongswan drivers support except regular group also Elliptic Curve Groups also NIST and Brainpool Elliptic Curve Groups. https://wiki.strongswan.org/projects/strongswan/wiki/IKEv2CipherSuites#Diff…. I would like to know, if there is some limitation using Elliptic Curve groups for VPN or is this only an implementation issue? Thanks, Matus

[cinder] How to post multiple patches.
by 野村和正 / NOMURA，KAZUMASA 19 Apr '21

19 Apr '21

Hi everyone, Hitachi has developed the out-of-tree driver as Cinder driver. But we want to deprecate the out-of-tree driver and support only the in-tree driver. We need to submit about ten more patches(*1) for full features which the out-of-tree driver has such as Consistency Group and Volume Replication. In that case, we have two options: 1. Submit two or three patches at once. In other words, submit two or three patches to Xena, then submit another two or three patches after previous patches were merged, and so on. This may give reviewers the feeling of endless. 2. Submit all patches at once to Xena. This will give reviewers the information how many patches remains from the beginning, but many pathes may bother them. Does anyone have an opinion as to which option is better? Thanks, Kazumasa Nomura E-mail: kazumasa.nomura.rx(a)hitachi.com<mailto:kazumasa.nomura.rx@hitachi.com>

[Murano] Please help with murano image creation

Hello, we want to create the murano image for an openstack victoria deployment. We tried to follow this documentation: https://docs.openstack.org/murano/victoria/reference/appendix/articles/imag… But we were not able to successfully create an image. At first we got the following error: murano-agent requires Python '>=3.6' but the running Python is 2.7.17 Then I changed the release to focal and got another error: Unable to locate package python-pip Is anybody so kind to help me with this problem?

[kolla] VM build fails after Train-Ussuri upgrade
by Braden, Albert 19 Apr '21

19 Apr '21

I upgraded my Train test cluster to Ussuri following these instructions: OpenStack Docs: Operating Kolla<https://docs.openstack.org/kolla-ansible/latest/user/operating-kolla.html#u…> The upgrade completed successfully with no failures, and the existing VMs are fine, but new VM build fails with rados.Rados.connect\nrados.PermissionDeniedError: Ubuntu Pastebin<https://paste.ubuntu.com/p/MJhzgjYbW8/> I'm running external ceph so I looked at this document: OpenStack Docs: External Ceph<https://docs.openstack.org/kolla-ansible/latest/reference/storage/external-…> It says that I need the following in /etc/kolla/config/glance/ceph.conf: auth_cluster_required = cephx auth_service_required = cephx auth_client_required = cephx I didn't have that, so I added it and then redeployed, but still can't build VMs. I tried adding the same to all copies of ceph.conf and redeployed again, but that didn't help. Does anything else need to change in my ceph config when upgrading from Train to Ussuri? I see some cryptic talk about ceph in the release notes but it's not obvious what I'm being asked to change: OpenStack Docs: Ussuri Series Release Notes<https://docs.openstack.org/releasenotes/kolla-ansible/ussuri.html#relnotes-…> I read the bug that it refers to: Bug #1904062 "external ceph cinder volume config breaks volumes ..." : Bugs : kolla-ansible (launchpad.net)<https://bugs.launchpad.net/kolla-ansible/+bug/1904062> But I already have "backend_host=rbd:volumes" so I don't think I'm hitting that. Also I read these sections but I don't see anything obvious here that needs to be changed: * For cinder (cinder-volume and cinder-backup), glance-api and manila keyrings behavior has changed and Kolla Ansible deployment will not copy those keys using wildcards (ceph.*), instead will use newly introduced variables. Your environment may render unusable after an upgrade if your keys in /etc/kolla/config do not match default values for introduced variables. * The default behavior for generating the cinder.conf template has changed. An rbd-1 section will be generated when external Ceph functionality is used, i.e. cinder_backend_ceph is set to true. Previously it was only included when Kolla Ansible internal Ceph deployment mechanism was used. * The rbd section of nova.conf for nova-compute is now generated when nova_backend is set to "rbd". Previously it was only generated when both enable_ceph was "yes" and nova_backend was set to "rbd". My ceph keys have the default name and are in the default locations. I have cinder_backend_ceph: "yes". I don't have a nova_backend setting but I have nova_backend_ceph: "yes" I added nova_backend: "rbd" and redeployed and now I get a different error: rados.Rados.connect\nrados.ObjectNotFound Ubuntu Pastebin<https://paste.ubuntu.com/p/2kdKCW7npw/> I apologize for the nonsense below.
