[URGENT][ACTION REQUIRED] vdsm versioning system need to be fixed
by Sandro Bonazzola 08 Mar '16

08 Mar '16

Hi, I think I already raised the issue several times, but let me raise this again. VDSM building / automated versioning is badly broken. Currently, 3.6 snapshot is building: vdsm-4.17.19-32.git171584b.el7.centos.src.rpm <http://jenkins.ovirt.org/job/vdsm_3.6_build-artifacts-el7-x86_64/178/artifa…> because the last tag on the 3.6 branch was 4.17.19 and new tags have been created in different branches. This make impossible to upgrade from stable (4.17.23) to latest snapshot. This also break dependencies on other projects requiring the latest released version like hosted engine. Please fix the automated versioning system vdsm is currently using or get rid of it. Thanks, -- Sandro Bonazzola Better technology. Faster innovation. Powered by community collaboration.

How can users use oVirtCli to complete "run once"?
by zhukaijie 08 Mar '16

As you know. In web, users can use "RUN ONCE" button to run a VM with some params (such as certain custom properties). But can oVirtCli be used to complete "RUN ONCE"? Thank you.

Hi, Has anyone ever used vdsm hooks in RHEL 7.2 on to of 3.6 ? I faced some issues with that, related to emulated machines [root@localhost ~]# tail -f /var/log/vdsm/vdsm.log |grep ':ERROR:' Thread-18::ERROR::2016-03-06 07:43:57,019::caps::195::root::(_get_emulated_machines_from_domain) Error while looking for kvm domain (x86_64) libvirt capabilities -Eldad

logging VDSM-generated libvirt XML properly
by Martin Polednik 07 Mar '16

07 Mar '16

Hello developers! I've been chasing a bug that lead me to an idea of improving our XML logging. Now, to see a VMs generated libvirt XML, we have to rely on vdsm.log. The issue is that the log is rotating and therefore, it is easy to miss the correct XML when dealing with busy hypervisor. Since we're built on libvirt, I was thinking of doing similar thinks that libvirt does with qemu commandline. Each running domain(VM) has it's command line logged in /var/log/libvirt/qemu/${vmname}. This is great for debugging as you can mostly just take the cmdline and restart the VM. There is an issue with using the cmdline directly - networking. Libvirt uses additional script to create and up a bridge. Therefore, it is easier to use the XML and shape it to one's needs. I propose that we properly log the generated XML in a similar fashion as libvirt generates the cmdline. This means we would have path like /var/log/vdsm/libvirt/${vmname}, where generated XML would be stored. To minimize the logging requirements, only last definition of VM with that name may be stored. Additionally, exception level errors related to that VM could also be stored there. What do you think, can we afford the space and additional writes per VM to help the debugging process? Regards, mpolednik

Engine High Availability
by Sunny Shin 06 Mar '16

06 Mar '16

Hi All, In the new architecture page ( http://www.ovirt.org/documentation/architecture/architecture/) overall architecture picture shows that engine supports active-active high availability. However, as per engine HA page ( http://www.ovirt.org/develop/release-management/features/engine/engine-high…) active-active HA is not supported yet and there are several implementation issues. So, could anyone give me a brief explanation about discrepancy between these two pages, and about the plan to implement this feature if not implemented yet? Sunny

Allow access to Cockpit by default after adding a host? Or make it configurable in Engine?
by Fabian Deutsch 04 Mar '16

04 Mar '16

Hey, Node Next will ship Cockpit by default. When the host is getting installed, Cockpit can be reached by default over it's port 9090/tcp. But after the host was added to Engine, Engine/vdsm is setting up it's own iptables rules which then prevent further access to Cockpit. How do we want users to control the access to Cockpit? So where shall users be able to open or close the Cockpit firewall port. Initially I thought that we can open up the cockpit port by default, but this might be a security issue. (Brute force attacks to crack user passwords through the web interface). - fabian
