Firewalld migration.
by Leon Goldberg
Hey,
We're looking to migrate from iptables to firewalld. We came up with a
couple of possible approaches we'd like opinions on. I'll list the options
first, and will
1) Replicate existing flow:
As of date, iptable rules are inserted in the database via SQL config
files. During host deployment, VdsDeployIptablesUnit adds the required
rules (based on cluster/firewall configuration) to the deployment
configuration, en route to being deployed on the host via otopi and its
iptables plugin.
Pros:
- Reuse of existing infrastructure.
Cons:
- Current infrastructure is overly complex...
- Many of the required services are provided by firewalld. Rewriting them
is wasteful; specifying them (instead of providing actual service .xml
content) will require adaptations on both (engine/host) sides. More on that
later.
2) Host side based configuration:
Essentially, all the required logic (aforementioned cluster/firewall
configuration) to determine if/how firewalld should be deployed could be
passed on to the host via ohd. Vdsm could take on the responsibility of
examining the relevant configuration, and then creating and/or adding the
required services (using vdsm.conf and vdsm-tool).
Pros:
- Engine side involvement is greatly diminished.
- Simple(r).
Cons:
- Custom services/rules capabilities will have to be rethought and
re-implemented (current infrastructure supports custom iptables rules by
being specified in the SQL config file).
3) Some other hybrid approach:
If we're able to guarantee all the required firewalld services are
statically provided one way or the other, the current procedure could be
replicated and be made more simpler. Instead of providing xml content in
the form of strings, service names could be supplied. The responsibility of
actual service deployment becomes easier, and could be left to otopi (with
the appropriate modifications) or switched over to vdsm.
--
Regardless, usage of statically provided vs. dynamically created services
remains an open question. I think we'd like to avoid implementing logic
that ask whether some service is provided (and then write it if it
isn't...), and so choosing between the dynamic and static approaches is
also needed. Using the static approach, guaranteeing *all* services are
provided will be required.
I do believe guaranteeing the presence of all required services is worth
it, however custom services aren't going to be naively compatible, and
we'll still have to use similar mechanism as described in #1 (service
string -> .xml -> addition of service name to active zone).
Your thoughts are welcome.
Thanks,
Leon

[ANN] oVirt 4.1.1 Async release candidate
by Sandro Bonazzola
Hi,
following oVirt 4.1.1 GA the oVirt team identified some bugs worth to be
addressed out of the usual release cycle.
For this reason an async release including these fixes is under preparation.
An update to the following packages have been pushed to the pre-release
repository for testing.
- cockpit-ovirt-0.10.7-0.0.16
- imgbased-0.9.20
- ovirt-engine-4.1.1.8
- ovirt-engine-metrics-1.0.2
- ovirt-release41-4.1.1.1
- ovirt-web-ui-0.1.2-4
- vdsm-jsonrpc-java-1.3.10
- vdsm v4.19.10.1
In order to test it, you'll need pre-release repository enabled:
yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release41-pre.rpm
An update to release notes including bugs related to above packages and
updates applied in bugzilla documentation texts has been pushed
tohttps://github.com/oVirt/ovirt-site/pull/888 for review.
On behalf of the oVirt team,

Live demo session on how to debug oVirt GWT applications
by Vojtech Szocs
Hello UI devs,
with oVirt master UI using the latest GWT SDK [1], I'd like to host a live
demo session with two goals in mind:
a, explain how the (Java IDE based) Classic Dev Mode works and mention its
limitations
b, explain how the (browser based) Super Dev Mode works and encourage
people to start using it to boost their productivity
[1] http://www.mail-archive.com/devel@ovirt.org/msg08558.html
The Classic vs. Super Dev Mode are two possible ways to debug GWT
applications. This session will give you the knowledge to decide which one
to use in a specific situation.
Proposed time: Mon, Apr 3 @ 5pm CET / 6pm TLV / 11am US EST. (This can be
changed as needed.)
Let me know if this kind of session interests you or if the above time
doesn't fit you but you'd still like to join.
Thanks,
Vojtech

I will be performing updates on gerrit.ovirt.org during the next hour.
Within this period the UI and repositories may be unavailable.
I will follow up as soon as maintenance activities are over.

Gluster/virt ports clarifications.
by Leon Goldberg
Hey,
We're gathering information regarding the ports we open as part of the
firewalld migration research.
We have most of the current ports covered by either firewalld itself or by
3rd party packages, however some questions remain unanswered:
IPTablesConfigForVirt:
- serial consoles (tcp/2223): Is this required? can't find a single
reference to a listening entity. Either way, I couldn't find a relevant
service that provides it.
IPTablesConfigForGluster:
- Gluster swift (tcp/8080): Doesn't appear in Gluster's firewalld service.
Should be added to Gluster's firewalld service?
- tcp/39543 and tcp/55863, appear under "status". Couldn't find a relevant
service that provides them. Should be added? (and if so, where?)
- nlockmgr (tcp/38468, udp/963, tcp/965): tcp/38468 appears in gluster's
service. Couldn't find a relevant service that provides the other two.
Should be added? (and if so, where?)
- ctdbd (tcp/4379): Couldn't find a relevant service that provides this.
Should be added? (and if so, where?)
Thanks,
Leon
