Ceph Cinder QoS
by Matteo Dacrema 15 Mar '18

15 Mar '18

Hi All, I’m running a 4.2 cluster with all VMs on Ceph using cinder external provider. I’m trying to limit IOPS with cinder qos and volume type but it doesn’t work. VM xml doesn’t show anything about <iotune> Is it expected to work or is not implemented yet? Thank you Matteo

Failure to upgrade Cluster Compatibility Version
by Jonathan Mathews 12 Mar '18

12 Mar '18

I have been upgrading my oVirt platform from 3.4 and I am trying to get to 4.2. I have managed to get the platform to 3.6, but need to upgrade the Cluster Compatibility Version. When I select 3.6 in the Cluster Compatibility Version and select OK, it highlights Compatibility Version in red, (image attached). There are no errors been displayed on screen, or in the /var/log/ovirt-engine/engine.log file. Please let me know if I am missing something and how I can resolve this? Thanks Jonathan

ovirt 4.2 gluster configuration
by Edoardo Mazza 08 Mar '18

08 Mar '18

Hi all, Scenario: 3 nodes each with 3 interfaces: 1 for management, 1 for gluster, 1 for VMs Management interface has it own name and its own ip (es. name = ov1, ip= 192.168.1.1/24), the same is for gluster interface which has its own name and its own ip (es. name = gluster1, ip= 192.168.2.1/24). When configuring bricks from Ovirt Management tools I get the error: "no uuid for the name ov1". Network for gluster communication has been defined on network/interface gluster1. What's wrong with this configuration? Thanks in advance. Edoardo

ovirt 4.1 - skylake - no avx512 support in virtual machines
by Marco Lorenzo Crociani 05 Mar '18

05 Mar '18

Hi, I can't access avx512* instruction set from virtual machines. I have made a one server compute cluster to test new hardware: oVirt 4.1.9 CentOS 7 Cluster CPU Type: Intel Skylake Family Compatibility Version: 4.1 HOST: CPU Model Name:Intel(R) Xeon(R) Platinum 8180 CPU @ 2.50GHz Family: Family CPU Type: Intel Skylake Family Virtual Machine settings A) VM: Custom CPU Type: Use cluster default(Intel Skylake Family) General Tab shows: Guest CPU Type: Skylake-Client avx512: NO B) VM: Custom CPU Type: Skylake-Client General Tab shows: Guest CPU Type: Skylake-Client avx512: NO C) VM: Custom CPU Type: Use cluster default(Intel Skylake Family) [grey - cannot modify] Migration mode: Do not allow migration Pass-Through Host CPU General Tab shows: Guest CPU Type: Skylake-Client avx512: YES ( cat /proc/cpuinfo |grep avx512: avx512f avx512dq avx512cd avx512bw avx512vl ) Using pass-through host cpu (disabling vm migration) is the only way to access avx512 in a VM, is it a bug or am I missing something?

oVIRT 4.1 / iSCSI Multipathing
by Devin Acosta 05 Mar '18

05 Mar '18

I am using the latest release of oVIRT 4.1.3, and I am connecting a Dell Compelent SAN that has 2 fault domains each on a separate VLAN that I have attached to oVIRT. From what I understand I am suppose to go into “iSCSI Multipathing” option and add a BOND of the iSCSI interfaces. I have done this selecting the 2 logical networks together for iSCSI. I notice that there is an option below to select Storage Targets but if I select the storage targets below with the logical networks the the cluster goes crazy and appears to be mad. Storage, Nodes, and everything goes offline even thought I have NFS also attached to the cluster. How should this best be configured. What we notice that happens is when the server reboots it seems to log into the SAN correctly but according the the Dell SAN it is only logged into once controller. So only pulls both fault domains from a single controller. Please Advise. Devin

Can't move/copy VM disks between Data Centers

VM paused rather than migrate to another hosts
by Terry hey 05 Mar '18

05 Mar '18

Dear all, I am testing iSCSI bonding failover test on oVirt, but i observed that VM were paused and did not migrate to another host. Please see the details as follows. I have two hypervisors. Since they are running iLO 5 and oVirt 4.2 cannot support iLO 5, thus i cannot setup power management. For the cluster setting, I set "Migrate Virtual Machines" under the Migration Policy. For each hypervisor, I bonded two iSCSI interface as bond 1. I created one Virtual machine and enable high availability on it. Also, I created one Virtual machine and did not enable high availability on it. When i shutdown one of the iSCSI interface, nothing happened. But when i shutdown both iSCSI interface, VM in that hosts were paused and did not migrate to another hosts. Is this behavior normal or i miss something? Thank you all of you. Regards, Terry Hung
