DRBD Integration with oVirt
by Hayley Swimelar 26 Jul '16

26 Jul '16

Hello all, A DRBD integration into oVirt is currently being planned. DRBD provides replicated, highly available block storage. For those unfamiliar with DRBD more information can be found here: https://www.drbd.org/en/comp/drbd-linux-driver DRBD 9 is the latest version of DRBD and interacts with DRBD Manage which is a daemon exposed via a D-Bus api. More information can be found here: https://www.drbd.org/en/comp/drbdmanage DRBD Manage handles the creation, assignment, etc. of DRBD volumes and is the interface through which Cinder manages DRBD. We are looking for advice on how best to have oVirt communicate with DRBD Manage and we have come to two options: 1) Use Cinder. Although we are integrated into Cinder, there are concerns about the need to set up a complete Cinder instance to provide access to DRBD. 2) The alternative to Cinder would be to have the oVirt Engine communicate directly to DRBD Manage via D-Bus. Any advice on the best way to achieve this would be much appreciated. -- Hayley Swimelar LINBIT | Keeping the Digital World Running DRBD — Corosync — Pacemaker +1-503-573-1262 x212

Blog post: Monitoring Improvements in oVirt
by Arik Hadas 25 Jul '16

25 Jul '16

Hi all, I wrote a blog post that summarizes the recent improvements in the code that monitors virtual machines in oVirt. It describes the changes that were done and shows a comparison of different aspects of oVirt with these changes (based on the master branch) vs oVirt 3.6 without these changes: http://ahadas.github.io/monitoring-improvements-in-ovirt/ It is mostly a technical post. However, users might find it interesting as well. Note that the measurements were taken on an environment with 1 host and 6000 running VMs (in a pool). Each VM had a network interface and was diskless. Obviously, this is not a typical setup but it was useful to easily expose some of weak sides of the monitoring. Your feedback is always welcome! Regards, Arik

anonymous upgrade script instead of tmp function ceremony
by Roy Golan 25 Jul '16

25 Jul '16

We all use the pattern of temporary creating a function for upgrade script, declaring it (copy pasting from last script) and then calling it, then deleting it. This very verbose can be replaced with DO instruction which does essentially the same. # existing declaration ```sql CREATE OR REPLACE FUNCTION __tmp_count() RETURNS VOID AS $procedure$ DECLARE i int; BEGIN i:= (select count(*) from vms) -- useless count just for the demo END; $procedure$ LANGUAGE plpgsql; SELECT __tmp_count(); DROP FUNCTION __tmp_acount(); ``` Can be replaced with ```sql DO $$ DECLARE i int; BEGIN i := (select count(*) from vms) -- useless count for demo END $$; ``` Not tested but tons of less lines to code. Exist in version 9.0.23 and above

changing engine domain name
by Paul Dyer 20 Jul '16

20 Jul '16

Hi, back in 2015, with the first install of ovirt, I used a domain of xxxportal.com. Since the client has an xxxcentral.com wildcard certificate, I added changed the hostname and domainname, and added the cert/cacert to the apache webpage. The pki on ovirt and vdsm (host) both still have the original xxxportal.com domain. I am looking for a way to wipe away the old domain. Do I need to remove the host (not hosted engine), drop the datacenter/cluster, and build from a clean db? Thanks, Paul -- Paul Dyer, Mercury Consulting Group, RHCE 504-302-8750
