oVirt Node on CentOS 7.5 and AMD EPYC Support

by Tobias Scheinert

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 --> <… [View More]

problems with aaa auth

by cmcl＠dneg.com

Hi, We've got problems authenticating using ldap accounts on the admin/vm portal. It reports: "Unable to log in. Verify your login information or contact the system administrator." We're running RHEV version 4.2.4.5-0.1.el7_3. I've tested ovirt-engine-extensions-tool using 'aaa login-user' with my profile name and a username and it auths fine. I can't find any log that might give a hint as to why it is failing. The ui.log is empty. It is also extremely slow (it spends a lot of time "waiting … [View More]

AMD Threadripper support

by Darin Schmidt

My Issue is that there isnt an option to select anything other than Opteron based AMD chips. Is there a way to add my CPU to the list? I have an AMD 2970wx Threadripper. I found an article stating that you can edit the postre database. But where do I find the info needed to add a CPU to the list? Also when I tried to follow the instructions, I get: -bash-4.2$ /opt/rh/rh-postgresql95/root/bin/psql -h localhost -p 5432 -U engine -W /opt/rh/rh-postgresql95/root/bin/psql: error while loading … [View More]

RAID L1/L5/L10 + NFS Loopback Benchmarks

by Andrei Verovski

Hi ! I run a series of benchmarks with IOZONE testing performance of different RAID configurations on HP ProLiant DL380 + impact of NFS loopback. NFS loopback is necessary even for very small systems (e.g. just 2 nodes), since oVirt local storage setup is limited to single (only one) node per data center and this is quite useless from the point of view of functionality.
