Hi, Look at [1], however there are caveats so be sure to pay close attention to the warning section.

cpu, core and thread mappings
by Gianluca Cecchi 06 Sep '17

06 Sep '17

Hello, I was talking with a guy expert in VMware and discussing performance of VMs in respect of virtual cpus assigned to them in relation with mapping with the real hw of the hypervisor underneath. One of the topics was numa usage and its overheads in case of a "too" big VM, in terms of both number of vcpus and memory amount. Eg: suppose host has 2 intel based sockets, with 6 cores and HT enabled and has 96Gb of ram (distributed 48+48 between the 2 processors) suppose I configure a VM with 16 vcpus (2:4:2): would be the mapping respected at physical level or only a sort of "hint" for the hypervisor? Can I say that it would perform better if I configure it 12 vcpus and mapping 1:6:2, because it can stay all inside one cpu? And what if I define a VM with 52Gb of ram? Can I say that it would perform in general better if I try to get it all in one cpu related memory slots (eg not more than 48Gb in my example)? Are there any documents going more deeply in these sort of considerations? Also, if one goes and sizes so that the biggest VM is able to all-stay inside one cpu-memory, does it make sense to say that it will perform better in this scenario a cluster composed by 4 nodes, each one with 1 socket and 48Gb of memory instead of a cluster of 2 nodes, each one with 2 sockets and 96Gb of ram? Hope I have clarified my questions/doubts. Thanks in advance for any insight, Gianluca

Slow booting host - restart loop
by Bernardo Juanicó 06 Sep '17

06 Sep '17

Hi everyone, I installed 2 hosts on a new cluster and the servers take a really long to boot up (about 8 minutes). When a host crashes or is powered off the ovirt-manager starts it via power management, since the servers takes all that time to boot up the ovirt-manager thinks it failed to start and proceeds to reboot it, several times before giving up, when the server is finally started (about 20 minutes after the failure) I changed some engine variables with engine-config trying to set a higher timeout, but the problem persists. Any ideas?? Regards, Bernardo PGP Key <http://pgp.mit.edu/pks/lookup?op=get&search=0x695E5BCE34263F5B> Skype: mattraken

VMs going in to non-responding state
by Satheesaran Sundaramoorthi 06 Sep '17

06 Sep '17

Hi All, I have created a converged setup with cluster having both virt and gluster capability. There are three hosts in this cluster, and this cluster also has enabled 'native access to gluster domain' which enables VM to use libgfapi access mechanism. With this setup, I see VMs created landing up in non-reponding state after sometime. I have raised bug[1] for this issue. Request for help with this issue [1] - https://bugzilla.redhat.com/show_bug.cgi?id=1488863 Advance Thanks. -- Satheesaran S ( sas )

Changes in Virt SIG in upcoming CentOS 1708
by Sandro Bonazzola 06 Sep '17

06 Sep '17

Hi, with upcoming CentOS 1708 all the SIGs have been asked to do some cleanup of old / unsupported stuff. As part of the cleanup, ovirt 3.5, 3.6 and 4.0 will be dropped from http://mirror.centos.org/centos/7/virt/x86_64/ Also, as part of the cleanup a few packages previously tagged in CentOS VIrt SIG repos and now available in CentOS base / optional / extras repo have been untagged and won't be in http://mirror.centos.org/centos/7/virt/x86_64/ when the repo will be re-generated from tags. As a side effect, you may see cockpit related packages not available if you're running oVirt on RHEL 7.4 instead of CentOS 7.1708 because on CentOS 7 extras channel is enabled by default while on RHEL you need to enable it manually. Thanks, -- SANDRO BONAZZOLA ASSOCIATE MANAGER, SOFTWARE ENGINEERING, EMEA ENG VIRTUALIZATION R&D Red Hat EMEA <https://www.redhat.com/> <https://red.ht/sig> TRIED. TESTED.

[QA] fluentd-0.12.39-1.el7
by Sandro Bonazzola 06 Sep '17

06 Sep '17

Hi, CentOS OpsTools SIG tagged fluentd-0.12.39-1.el7 <http://cbs.centos.org/koji/buildinfo?buildID=19053> and rubygem-cool.io-1.5.1-1.el7 <http://cbs.centos.org/koji/buildinfo?buildID=19649> for testing and will probably move soon to release repo. Before it happens, if you're already using it can you please provide feedback on its goodness on oVirt environment? I don't see critical changes from 0.12.37 but some feedback would help. Testing yum repository is https://buildlogs.centos.org/centos/7/opstools/x86_64/ and is already used in our CI without any breakage reported so far. Thanks to whoever volunteer for this testing. -- SANDRO BONAZZOLA ASSOCIATE MANAGER, SOFTWARE ENGINEERING, EMEA ENG VIRTUALIZATION R&D Red Hat EMEA <https://www.redhat.com/> <https://red.ht/sig> TRIED.
