Hi, I'm running Version 4.2.3.8-1.el7, and after reboot the engine machine no longer could login into administration portal with this error: sun.security.validator.ValidatorException: PKIX path validation faile java.security.cert.CertPathValidatorException: validity check failed I'm using a self signed cert. Any idea? Thanks -- Jose Ferradeira http://www.logicworks.pt

Ovirt cluster unstable; gluster to blame (again)
by Jim Kusznir 04 Feb '19

04 Feb '19

hi all: Once again my production ovirt cluster is collapsing in on itself. My servers are intermittently unavailable or degrading, customers are noticing and calling in. This seems to be yet another gluster failure that I haven't been able to pin down. I posted about this a while ago, but didn't get anywhere (no replies that I found). The problem started out as a glusterfsd process consuming large amounts of ram (up to the point where ram and swap were exhausted and the kernel OOM killer killed off the glusterfsd process). For reasons not clear to me at this time, that resulted in any VMs running on that host and that gluster volume to be paused with I/O error (the glusterfs process is usually unharmed; why it didn't continue I/O with other servers is confusing to me). I have 3 servers and a total of 4 gluster volumes (engine, iso, data, and data-hdd). The first 3 are replica 2+arb; the 4th (data-hdd) is replica 3. The first 3 are backed by an LVM partition (some thin provisioned) on an SSD; the 4th is on a seagate hybrid disk (hdd + some internal flash for acceleration). data-hdd is the only thing on the disk. Servers are Dell R610 with the PERC/6i raid card, with the disks individually passed through to the OS (no raid enabled). The above RAM usage issue came from the data-hdd volume. Yesterday, I cought one of the glusterfsd high ram usage before the OOM-Killer had to run. I was able to migrate the VMs off the machine and for good measure, reboot the entire machine (after taking this opportunity to run the software updates that ovirt said were pending). Upon booting back up, the necessary volume healing began. However, this time, the healing caused all three servers to go to very, very high load averages (I saw just under 200 on one server; typically they've been 40-70) with top reporting IO Wait at 7-20%. Network for this volume is a dedicated gig network. According to bwm-ng, initially the network bandwidth would hit 50MB/s (yes, bytes), but tailed off to mostly in the kB/s for a while. All machines' load averages were still 40+ and gluster volume heal data-hdd info reported 5 items needing healing. Server's were intermittently experiencing IO issues, even on the 3 gluster volumes that appeared largely unaffected. Even the OS activities on the hosts itself (logging in, running commands) would often be very delayed. The ovirt engine was seemingly randomly throwing engine down / engine up / engine failed notifications. Responsiveness on ANY VM was horrific most of the time, with random VMs being inaccessible. I let the gluster heal run overnight. By morning, there were still 5 items needing healing, all three servers were still experiencing high load, and servers were still largely unstable. I've noticed that all of my ovirt outages (and I've had a lot, way more than is acceptable for a production cluster) have come from gluster. I still have 3 VMs who's hard disk images have become corrupted by my last gluster crash that I haven't had time to repair / rebuild yet (I believe this crash was caused by the OOM issue previously mentioned, but I didn't know it at the time). Is gluster really ready for production yet? It seems so unstable to me.... I'm looking at replacing gluster with a dedicated NFS server likely FreeNAS. Any suggestions? What is the "right" way to do production storage on this (3 node cluster)? Can I get this gluster volume stable enough to get my VMs to run reliably again until I can deploy another storage solution? --Jim

Out of sync, hosts network config differs from DC
by femi adegoke 02 Dec '18

02 Dec '18

Property: default route, host - true, DC - false I have 4 nics. bond0 = 2 x 10g eno1 = ovirtmgmt eno2 = for vm traffic. eno2 says it's out of sync, hosts network config differs from DC, default route: host - true, DC - false. I have tried "sync all networks" but the message still remains See attached. Where can I look to fix the issue?

oVirt Node on CentOS 7.5 and AMD EPYC Support
by Tobias Scheinert 30 Nov '18

30 Nov '18

Hi, I am currently building a new virtualization cluster with oVirt, using AMD EPYC processors (AMD EPYC 7351P). At the moment I'm running oVirt Node Version 4.2.3 @ CentOS 7.4.1708. We have the situation that the processor type is recognized as "AMD Opteron G3". With this type of instruction set the VMs are not able to do AES in hardware, this results in poor performance in our case. I found some information that tells me that this problem should be solved with CentOS 7.5 --> <https://access.redhat.com/errata/RHEA-2018:1488> My actual questions: - Are there any further information about the AMD EPYC support? - Any information about an update of the oVirt node to CentOS 7.5? Greeting Tobias

VLAN tagging with external provider networks
by anurag.porripireddi＠bigswitch.com 12 Oct '18

Hi, I see that checking the "External provider" box whilst creating networks clears and grays out VLAN tagging. Is VLAN tagging for external provider networks not supported? Thanks, Anurag

Info on HCI single host
by Gianluca Cecchi 11 Oct '18

11 Oct '18

Hello, following this reference guide: https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Single_node… after having run with success the gdeploy based gluster setup, there is Setting up Hosted Engine Use the Ansible based installation flow of Hosted Engine to set up oVirt within a virtual machine. The storage details should be provided as type: glusterfs and connection path as: <hostname>:/engine (Replace hostname with address of host on which installation is carried out) What does exactly mean "Use the Ansible based instalation" ? Does it mean using cockpit web ui? In this casae I suppose I have to choose: Hosted Engine Deploy oVirt hosted engine on storage that has already been provisioned Correct? Thanks, Gianluca

[OT] transferring kvm raw mage from filesystem to lvm based
by Gianluca Cecchi 02 Oct '18

02 Oct '18

Hello, I have a windows 7 VM that is composed by a raw disk on filesystem on Fedora 28. I would like to transfer this VM to another environment, always based on same version of Fedora 28, but where the storage is configured in virt-manager as lvm based, so similar to what happens in oVirt block based storage domains. I'm trying to figure how to transfer the image. I presume I can create a new LV and then leave some bytes for the LVM header into the created LV and then make a sort of dd with offset? Anyone has any hint? Thanks in advance, Gianluca

Slow vm transfer speed from vmware esxi 5
by Bernhard Dick 20 Sep '18

20 Sep '18

Hi, currently I'm trying to move VMs from our vsphere 5 environment to oVirt. While the io performance on oVirt and on the esxi platform is quite well (about 100MByte/sec on a 1GBit storage link) the transfer speed using the integrated v2v-feature is very slow (only 10MByte/sec). That would result in transfer time of >24h for some machines. Do you have any ideas how I can improve the transfer speed? Regards Bernhard Dick
