Error while making hosts
by krisibo01＠gmail.com
Hello,
I am a student and as a school project i have to make virtual environment using oVirt. I just installed the oVirt-engine with the recomended configuration in the documentation and when i try to make a new host i got this error:
Error while executing action: Cannot add Host. Connecting to host via SSH has failed, verify that the host is reachable (IP address, routable address etc.) You may refer to the engine.log file for further details.
When i checked the log file the only thing that was there is that there is:
2020-02-06 03:59:24,594-05 ERROR [org.ovirt.engine.core.bll.hostdeploy.AddVdsCommand] (default task-30) [d54ee4df-32c8-474c-b315-51ad1131091a] Failed to establish session with host 'test': SSH connection timed out connecting to 'root(a)10.10.0.20'
I was trying to make the host following this steps:
Adding a Host to the oVirt Engine
1.Click Compute → Hosts.
2.Click New.
3.Use the drop-down list to select the Data Center and Host Cluster for the new host.
4.Enter the Name and the Hostname of the new host. The standard SSH port, port 22, is auto-filled in the SSH Port field.
5.Select an authentication method to use for the Engine to access the host.
Enter the root user’s password to use password authentication.
Alternatively, copy the key displayed in the SSH PublicKey field to /root/.ssh/authorized_keys on the host to use public key authentication.
6.Click the Advanced Parameters button to expand the advanced host settings.
i. Optionally disable automatic firewall configuration.
ii. Optionally add a host SSH fingerprint to increase security. You can add it manually, or fetch it automatically.
7.Optionally configure Power Management, SPM, Console, Network Provider, and Kernel. See Explanation of Settings and Controls in the New Host and Edit Host Windows for more information. Hosted Engine is used when deploying or undeploying a host for a self-hosted engine deployment.
8.Click OK.
The new host displays in the list of hosts with a status of Installing, and you can view the progress of the installation in the details pane. After a brief delay the host status changes to Up.

Re: Power Management - drac5
by eevans＠digitaldatatechs.com
I have the same issue on Dell R710's. Power management is optional and I don't use it. It doesn't affect it either way. I am connected to APC Smart UPS 3000. It will not find the apc either.
Any other opinions would be welcome. He's right, no documentation about this issue.

Subject: [ovirt-users] Power Management - drac5
I have 3 Dell R410's with iDrac6 Enterprise capability. I am trying to get power management set up but the test will not pass and I am not finding the docs very helpful.
I have put in the IP, user name, password, and drac5 as the type. I have tested both with and without secure checked and always get, "Test failed: Internal JSON-RPC error".
idrac log shows:
2020 Feb 3 17:41:22 os[19772] root closing session from 192.168.1.12
2020 Feb 3 17:41:17 os[19746] root login from 192.168.1.12
Can someone please guide me in the right direction?

I put the host in maintenance and activated it again, this should give
you some more info. See attached log.

Installing hosts w/o node installer
by Christian Reiss
Hey folks,
quick question: If I would like to use specific versions (contained
within the host) and craft myself a specific environment for the hosts
am I correct to assume that only installing the ovirt repo and a gluster
version of my choice (cough, 7.0) would suffice? Then adding the host
via an engine (and taking the ususal steps as you would for an ovirt
node: ssh keys et all)?
To my understanding the rollout is done via ansible so packages will be
installed if not present? The installation is pretty vague on this point
(https://www.ovirt.org/download/):
1. Enable the Base, Optional, and Extra repositories
2. Install Cockpit and the cockpit-ovirt-dashboard plugin:
3. Enable Cockpit
4. Open the firewall
5. - 9. Deploy using a hosted engine.
So, by using a remote engine (aka, like an additional host):
1. Enable the Base, Optional, and Extra repositories
the end?
I would use CentOS 7 as a base which I am very familiar with. I would
also setup Gluster by hand so "Only" the virtualization part needs to be
done.
This would, among other things, grant me perfect host recovery options
for a 1-host disaster case. We are looking at a base CentOS7 install
without any deep modifications (except for some packages etc).
Enjoy your weekend, all! :-)
-Christian.

Re: Win Server 2k19 and BlueIris

This also fixed the previous issues I was having with 2k19 servers that I was trying to migrate the disk image from Proxmox that was throwing the BSOD of KMODE EXCEPTION.

So after some digging, it seems this has been reported as an issue many times.
As a workaround, I added the an entry to the kvm.conf in modprobe.d directory of ignore_msrs=1 and that allowed Blue Iris to boot.
Would be nice to have an actual fix for this instead of a workaround. Would really like to know why kvm is thing that ia32_debugctl is not a valid cpu option.

So I have been running Windows Server 2019 on Proxmox VE with Blue Iris NVR. Tried to migrate the qcow disk over to oVirt, and like other Win2k19 servers, they all give a BSOD with a KMODE error.
Last night I installed 2k19 from scratch, installed the latest drivers I could find, oVirt-toolsSetup-4.3-3.el7, and proceeded to load up Blue Iris. As soon as I go to start Blue Iris, the VM hangs, then gives a BSOD with SYSTEM SERVICE EXCEPTION.
Looking at the debug log on the ovirt node the VM is running, there one entry that gets created on each crash with, "kvm [4723]: vcpu1 kvm_set_msr_common: MSR_IA32_DEBUGCTLMSR 0x1, nop".
Running on oVirt node 4.3.8, cluster cpu is Intel Westmere IBRS SSBD Family, pc-i440fx-rhel7.6.0, and the physical cpu is 24x Intel(R) Xeon(R) CPU X5670 @ 2.93GHz.
Any ideas?
