Actually there are SDKs for other languages: https://gerrit.ovirt.org/#/admin/projects/?filter=sdk https://github.com/oVirt?q=sdk&type=&language= JS is empty, but the others are more-or-less alive. Python is indeed the most "invested", at least in terms of number of example scripts, but IIUC all of them are generated, so should be complete.

[ovirt-users] Re: Q: Which types of tests and tools are used?
You can look into ovirt vdsm pytest readme [1], it is slightly outdated as invocation for 4.4 branch is now using "tox -e storage" (with no "-pyXX" suffix as all tests are python3 compatible there) All up2date options are listed on tox.ini [2]. If you need to set up your vdsm dev/test env you can follow [3]. For engine tests example, you can look at maven tests readme for DB models [4] [1] https://github.com/oVirt/vdsm/blob/master/tests/README [2] https://github.com/oVirt/vdsm/blob/master/tox.ini [3] https://github.com/oVirt/vdsm/blob/master/README.md [4] https://github.com/oVirt/ovirt-engine/blob/ede62008318d924556bc9dfc5710d90e9519670d/backend/manager/modules/dal/README On Sun, May 31, 2020 at 10:46 PM Juergen Novak wrote: > Hi, > > can anybody help me to find some information about test types used in > the project and tools used? > > Particularly interesting would be tools and tests used for the Python > coding, but also any information about Java would be appreciated. > > > I already scanned the documentation, but I mainly found only information > about Mocking tools. > > Thank you! > > /juergen > ___ > Users mailing list -- users@ovirt.org > To unsubscribe send an email to users-le...@ovirt.org > Privacy Statement: https://www.ovirt.org/privacy-policy.html > oVirt Code of Conduct: > https://www.ovirt.org/community/about/community-guidelines/ > List Archives: > https://lists.ovirt.org/archives/list/users@ovirt.org/message/OVHS6QUEGSNLZRKXIKDQFR6PKYKL4CBE/ > ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/HUBVO5J6Q3SJUP53CCIZM45SP6TYBZZH/

Check the libvirt logs on the host where the VM was running. In the engine, you can check the logs for any fencing, but I have never seen such thing as "excessive CPU allocation" to cause fencing. Either the VM passes the checks (overcommit rules, scheduling,etc) and gets up and running or the engine will refuse to power it up. Also check via journalctl for any messages at that time for the 'sanlock.service' . Any issues (storage unavailable or high lattency detected) will be reported via the sanlock service on the affected node. If you use multipath - check if it also reported any paths failing. >Now what I need to know is how to properly allocate CPU resources to a >host to run multiple virtual machines in it like the situation above. The best way is to start with less CPUs as possible. Here is a short (or maybe not) example: Hoypervisor has 8 CPUs/8 Threads. First VM has 1 CPU. Second has 6 CPUs allocated and a third VM has 8 CPUs allocated. For the hypervisor to allocate CPU time for the third (beefy) VM, it needs to have all 8 CPUs available. As the host itself has 8 cores and usually some OS stuff is going on - the third VM will receive far less CPU time than first/second VM. >I even tried to look for errors in vdsm.log, but this log was not >available in the host machine nor in the affected VM.

Interesting question... I think they just assumed. In worst case scenario (CPU starvation), the vdsmd service might not respond to the engine, but then a 'soft' reboot will happen where the engine will restart this service over ssh. >___ >Users mailing list -- users@ovirt.org >To unsubscribe send an email to users-le...@ovirt.org >Privacy Statement: https://www.ovirt.org/privacy-policy.html >oVirt Code of Conduct: >https://www.ovirt.org/community/about/community-guidelines/ >List Archives: >https://lists.ovirt.org/archives/list/users@ovirt.org/message/QX7NAZQ67VBA3KLPYIOXYSTPNU46XOBO/ Best Regards, Strahil Nikolov ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/SRD5TUJNKF32H2L6C47HEV4SQDILKLRV/

[ovirt-users] Problem with Ovirt Machines
Hi, Our company uses Ovirt to host some of its virtual machines. The version used is 4.2.6.4-1.el7. There are about 36 virtual hosts in it. The specifications used for the host machine is 30G RAM and 6 CPUs. Some of the VMs in the ovirt host run with 4 CPUs. Some with 2 CPUs. The problem I face now is that recently there was a need for high CPU and memory specs to setup a VM for DR. I created a VM with 16G RAM and 6 CPUs, without checking the CPUs available in the host first. After DR, the VM was brought down already. Then later another person in the team brought the VM back up for a different DR use, for a much larger DB restoration purpose. This caused the VM to pause due to storage error. And then worse things happened, whereby 2 other VMs inadvertently went down. Although I assumed that this was caused by storage errors/problems, the senior admins in the team concluded that the problem was due to fencing because of the max allotted CPU for the host being used for the VM. Now what I need to know is how to properly allocate CPU resources to a host to run multiple virtual machines in it like the situation above. I even tried to look for errors in vdsm.log, but this log was not available in the host machine nor in the affected VM. My colleague asked me to check "Events" section of the ovirt management interface to see past the past events. However, I don't find much details about the fencing activity or how the fencing occurred or what caused the fencing. And how did they conclude that the CPU count caused the fencing and not the storage? ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/QX7NAZQ67VBA3KLPYIOXYSTPNU46XOBO/
[ovirt-users] Re: Q: Fixing SELinux Permissions on oVirt node
When running from the terminal you are unconfined, hence it runs without error.
Probably your only option is to create custom policy to allow this. Although I
would question why the log file you are reading is cron_log_t and not var_log_t.

Hi !
I’m struggling with SELinux blocking SNMP script from reading log file (oVirt

Log file is readable by all (chmod ugo+r).
Scripts working fine when executed from terminal.
I did not dig deep into CentOS internals, I’m mostly use Debian and SuSE. As
far as I know, SELinux can’t be turned off on oVirt node.
Thanks in advance for any suggestion(s).
