oVirt Node install - kickstart postintall
by jeanbaptiste＠nfrance.com 14 Jan '19

14 Jan '19

Hello everybody, Since days, I'm trying to install oVirt (via Foreman) in network mode (TFTP net install). All is great, but I want to make some actions in postinstall (%post). Some actions are relatated to /etc/sysconfig/network-interfaces and another action is related to root authorized_keys. When I try to add pub-key to a created authorized_keys for root, I work (verified into anaconda. But after installation and anaconda reboot, I've noticed all my %post actions in /(root) are discared. After reboot, there is nothing in /root/.ssh for example. Whereas, in /etc, all my modications are preserved. I thought to a Selinux relative issue, but It is not relative to Selinux I miss something. Please can you help to understand how oVirt install / partition work ? thanks for all

Ovirt 4.3 / New Install / NFS (broken)
by Devin Acosta 14 Jan '19

14 Jan '19

I installed the latest 4.3 release candidate and tried to add an NFS mount to the Data Center, and it errors in the GUI with “Error while executing action New NFS Storage Domain: Invalid parameter”, then in the vdsm.log I see it is passing “block_size=None”. Does this regardless if NFS v3 or v4.

Trunk VLAN Ovirt 4.2
by Sebastian Antunez N. 14 Jan '19

14 Jan '19

Hello Guys Have a lab with 6 nodes Ovirt 4.2. All nodes have 4 nic 1GB and two nic are for Management and and I will assign two nic in bonding for VM traffic My problem is the following. The switch Cisco have 2 VLAN (56 and 57) and I need to be able to create a new network with the two vlan but I am not clear how to make it so that the vlan go through this created network. I have read that I must create a network with vlan 56 for example and assign it an IP, and then create the network with vlan 57 and assign it an IP and later assign it to bonding. Is what I indicate or should another process be correct? Thanks for the help. Sebastian

Once the bootstrap engine is ready on the "local" storage, you we move engine disk to shared storage, and you can remove the local storage.

This question is more about using ovirt, so the users mailing list is better. Others users may already solved this issue and can help more than developers which have much less experience with actual deployment. Nir

hosted-engine deploy Restore from backup failure
by Callum Smith 12 Jan '19

Restoring from backup appears to work perfectly, until it decides it hasn't worked and throws out. I can't see any relevant error here, does anyone have any insight?

Ovirt VDI Solution network issue
by mdcarr＠meditech.com 11 Jan '19

11 Jan '19

Hello, first time poster looking for help on setting up the network for a VDI deployment. A little background, I have Ovirt engine running on a Vmware virtual machine and have added a physical host to serve up virtual machines running windows 7 to our developers. The host has a static IP address and when I create a virtual machine I can see the default network is attached and up but does not receive an IP address. It does have a MAC so I'm wondering if I need to have our network team assign an IP for that MAC? I will be creating around 20 vm's that would get wiped after use so assigning static ip's might cause issues. Am I missing something or is there a better way to setup the LAN for this host? Thanks for any help!

Hypervisor host CPU utilization metrics
by Sigbjorn Lie-Soland 11 Jan '19

11 Jan '19

Hi, Linux see twice the amount of CPUs for a host with SMT/hyperthreading enabled. Inspecting the individual cores presented to the operating system using mpstat shows that the guests are running primarily on the “physical cores”, which is expected as the system is SMT aware. The “hyperthreaded cores” are showing guest activity when the host cpu is heavily loaded. Using the traditional tools such as top and vmstat does not take hyperthreading into consideration when calculating the total cpu% usage, again, as expected. How is the hypervisor host CPU utilization metrics in Ovirt calculated when a hypervisor host has SMT/hyperthreading enabled? Does Ovirt calculate in the same manner as the traditional vmstat/top/etc Linux tools, or does it only count CPU usage on the “physical cores” on the hypervisor? Does it read CPU metrics from the Intel PCM (https://github.com/opcm/pcm <https://github.com/opcm/pcm>) ? Does the “Count Threads as Cores” setting affect how the host hypervisor CPU utilization metrics are calculated? The reason for asking is when using tools for capacity and utilization reporting to attempt to establish cluster growth and to anticipate when and how much hypervisor capacity to add, we need the input utilization data to be a correct representation of what is happening at the hypervisor host. Thanks. Regards, Siggi

exporting VMs using vdsm-client

Is it possible to export VMs using vdsm-client to import into a new oVirt engine in a case of catastrophic failure such that they can be imported into a new setup?

quota_name field length missmatch in db schema
by Pavel Šipoš 11 Jan '19

11 Jan '19

Hi! We have a problem with Quotas whose name has a length grater than 60 characters. Such quotas can be created (or renamed) through oVirt-shell but cannot be managed through the oVirt Engine interface. E.g. VMs in that quota can't be started, created, quota comment can't be added... It turns out that the problem is with the engine database definition of "audit_log" table, that declares "quota_name" column as "character varying(60)". However "quota.quota_name" is defined as "character varying(65)". I think this is a bug and should be fixed in the future. Error example: PL/pgSQL function insertauditlog(integer,timestamp with time zone,integer,character varying,integer,text,uuid,character varying,uuid,character varying,uuid,character varying,uuid,character varying,uuid,character varying,uuid,character varying,uuid,character varying,uuid,character varying,character varying,uuid,uuid,character varying,text,boolean,uuid,text) line 9 at SQL statement; nested exception is org.postgresql.util.PSQLException: ERROR: value too long for type character varying(60) Regards, Pavel
