After updating Overt to 4.5.4, the network load graphs disappeared. Q: How is charting organized? What certificates are involved in data exchange?

/tmp/lvm.log keeps growing in Host
by kanehisa＠ktcsp.net 16 Apr '23

16 Apr '23

I don't understand why lvm.log is placed in /tmp directory without rotation. I noticed this fact when I got the following event notification every 2 hours. EventID ：24 Message ：Critical, Low disk space. Host ovirt01 has less than 500 MB of free space left on: /tmp. Low disk space might cause an issue upgrading this host. As a workaround, I added a log rotation setting to /tmp/lvm.log, but is this the correct way? I should have understood the contents of the Python program below before asking the question, but please forgive me because I am not very knowledgeable about Python. # cat /usr/lib/python3.6/site-packages/blivet/devicelibs/lvm.py | grep lvm.log config_string += "log {level=7 file=/tmp/lvm.log syslog=0}" Thanks in advance!!

4.5.2 hosted-engine deployment failed
by j9678＠hotmail.com 15 Apr '23

15 Apr '23

The engine deployment failed with message "Host is not up, please check logs, perhaps also on the engine machine" after "Wait for the host to be up". I couldn't find any particular error in setup log, it just failed without pointing out any reason. I've tried on ovirt node (el9 and el8) and RHEL 8.7.

Ovirt FQDN is not routing correctly and problems with CentOS 9
by aleksiallula＠gmail.com 15 Apr '23

15 Apr '23

I tried to configure ovirt for FQDN with local server but can not get it to work. This is what I added to /etc/hosts: 10.0.0.50 server.ovirt.com 10.0.0.51 server.ovirt2.com My hostname is server.ovirt.com and my IP address is 10.0.0.50. 10.0.0.51 is the hosted engine IP. I have added server.ovirt.com to "DNS search domains" of network card. I ask at the same time: is the difference between hosted engine and hyperconverged that with hyperconverged I could add the host to existing hosted engine ? First I tried to install OVirt to CentOS 9, but there is no "virtualization" menu at the OVirt main menu. So, I can not add the hosted engine setup. Now I try to setup the OVirt for CentOS 8 with this manual: https://anthonyspiteri.net/ovirt-kvm-homelab-1 and https://anthonyspiteri.net/ovirt-kvm-homelab-2. Any ideas how can I setup the FQDN and OVirt to work with CentOS 8 or 9 ? Is there some working repository where I can download the hosted engine version OVirt for CentOS 9 ?

I want to configure DHCP on my host. How do I do that?
by leezzzb12＠gmail.com 12 Apr '23

12 Apr '23

oVirt Version: 4.5 oVirt Engine : 1 unit oVirt Host : 3 units Virtual network configured ovirtmgmt, dhcp. dhcp gave vlan tagging as 50 and checked virtual machine network. Each host is configured to have two networks, ovirtmgmt and dhcp. I also set ipv4 to use DHCP, ipv6 also to use DHCP in the dhcp network. But no matter how long I wait on the host, I can't get the ipv4 and ipv6 IPs. 1. What did I do wrong? I've seen that using ovirt_provider_ovn you can configure DHCP. But I don't know how to configure it. 2. Is there a guide on how to configure it? 3. /etc/ovirt-provider-ovn/conf.d/10-setup-ovirt-provider-ovn.conf is configured as follows: The [DHCP] section is missing, is this required? 4. If you use ovirtmgmt (default network, static IP) when creating a virtual machine, is it correct that you cannot receive an IP? Please help me.

virt-viewer - working alternative
by lars.stolpe＠bvg.de 11 Apr '23

11 Apr '23

Hi all, i tryed to use virt-viewer 11 (Windows) with oVirt 4.4 . I also tryed virt-viewer 10, 9, 8, and 7. The older versions can't handle ISO residing in data domains, the latest version is crashing if try the media button. Almost all links on the website are dead, no user guide, no prerequisites list... Since virt-viewer is not working properly and seems to be abandoned, i'm looking for a working alternative. Is there a working way to get a console of the virtual machines running in oVirt 4.4?

I have many users and each user manages different devices, I made a label for the corresponding device and distributed the label to the corresponding user. The user needs to manually activate the label every time he logs in. How to activate the label by default?
