[ovirt-users] Re: Server 2008R2 UEFI ISO Boot Problerm

[Clint Boggio]

If I change to "Other OS" or any flavor of Linux i get the same result. I've 
changed the ISO to a W764 ISO as well with the same hang. More modern versions 
of Windows Server boot fine, but I am not able to restore the backup with a 
version higher than 2008R2.

This link "https://bugs.launchpad.net/qemu/+bug/1593605; references a similar 
problem that I am having and it's where I got the idea to pass the custom CPU 
flags.

[ovirt-users] Server 2008R2 UEFI ISO Boot Problerm

[Clint Boggio]

Greetings oVirt team

I'm using "Version 4.5.7-0.master.20240327074810.git14bca0502d.el8 on CentOS 
Stream 9"

I have occasion to restore a windows backup image for the purpose of data 
extraction. To accomplish this I need to boot off a Server 2008R2 ISO. The 
machine to be restored was UEFI based originally and so it is required to be 
UEFI for the restoration process.

I seem to be having a problem with booting off of the ISO image in the required 
UEFI-based system. In pursuit of a solution I've read on some of the other 
forums about this same problem on other KVM-based platforms.

Booting that same ISO after changing the VM to BIOS works flawlessly. In the 
articles and threads I've read there is mention of hyper-v services that load 
during the guest boot process that are causing the ISO boot to hang. 

Is it possible to disable (or is it even necessary to disable) 
"hv_time,hv_relaxed,hv_spinlocks=0x2000" in the "Custom Properties" section of 
the VM config ?

If any of you have some insight into this  problem and a possible solution I'd 
appreciate the feedback.

[ovirt-users] Re: Non responsive host (4.3.10)

[Clint Boggio]

Maria -

Likely you can repair the gluster volumes on that host with xfs_repair and you 
most likely need to stop the gluster service on that node and unmount the 
filesystems to do so.

After the filesystem is repaired you'll be able to mount them and start the 
gluster service. From there gluster will "heal" that node and your replica-3 
will be redundant again.

[ovirt-users] Re: oVirt Engine Web Console

[Clint Boggio]

You do have to use an FQDN to access it. The web management will not respond to 
IP address requests. When you set up the engine, what FQDN did you use ? In the 
hosts file of the machine you are using to access the engine, create an entry 
for that website:

Example:

10.10.254.10 your.fqdm.tld

or better example

10.10.254.10ovirtmgmt.yourdomain.com

[ovirt-users] Re: New oVirt HCI 4.5.4 Cluster Problems

[Clint Boggio]

Thank you Sandro.

I solved the problem by manually configuring Gluster storage on my three nodes 
and the running the engine-deploy utility to stand up the management engine.

I really appreciate you replying to my question. I know you're really busy.

[ovirt-users] New oVirt HCI 4.5.4 Cluster Problems

[Clint Boggio]

Good day all.

I'm in the process of deploying a fresh, new cluster and i'm running into a few 
snags. I'm trying to use the cockpit environment to deploy the gluster storage 
setup as I have previously done and it's failing consistently. I looked through 
what I believe to be the current documentation and I don't see anything about 
HCI setup, and the Gluster storage documentation points to the Gluster 
community web presence. 

So, my question is, will the oVirt HCI deployment still be supported, and is 
the process the same with cockpit to configure the storage, and cli to deploy 
the hosted engine or did HCI and gluster not make the cut with the 4.5.4 
release?

I'm using the oVirt node installation iso from the oVirt site for this 
deployment.

[ovirt-users] Re: oVirt 2.5.1.2 HCI Gluster Recovery Options

[Clint Boggio]

Good Day Strahil;

The OS did survive. The OS was on a RAID1 array and the gluster bricks are on a 
RAID5 array. Since the time I requested guidance I did a whole lot of reading 
and learning. I found in /etc/ansible several yaml files that contained the 
configuration of the gluster bricks and the lvm volumes contained within them. 
I also found that lvm configurations can be restored from /etc/lvm/backup and 
/etc/lvm/archive. All very helpfull I must say.

I re-created the RAID array and did a light initialization to wipe the array. 
Then I attempted to restore the backups from /etc/lvm/backup and 
/etc/lvm/array. I was unable to inspire the thinpool to enable with the "manual 
repair required" error each time. As there was not enough unused space on the 
system to cycle out the metadata lvm I was unable to proceed.

I then deleted the LVM configuration and re-created the LVM volumes from the 
/etc/ansible yaml files I found. I made them identical to the other two nodes 
that were functioning in the cluster. I have them succesfully mounted via fstab 
with the new UUID that were generated when I recreated the volumes. 

Based on the documents and articles I have read and studied these past few 
weeks, at this point I believe that I need to re-apply the appropriate 
gluster-related attributes to the correct level of the gluster mounts and 
attempt to start the gluster service. I have not done this yet because I don't 
want to cause another outage and I want to be sure that what I am doing will 
result in the afflicted gluster volumes healing and sychronising with the 
healthy nodes.

1. What attributes and at what level should I apply them to the refurbished 
node ?
2. What problems could I encounter when I try to start the gluster service 
after making the changes ?
3. Should I remove the new node from the gluster cluster and then re-add it or 
will it heal in it's current refurbished state ?

I appreciate you taking time to check on the status of this situation and thank 
you for any help or insight you can provide.

[ovirt-users] oVirt 2.5.1.2 HCI Gluster Recovery Options

[Clint Boggio]

Greetings oVirt community;

I've got a three-node HCI cluster with hosted engine and on one of the three 
nodes I lost the underlying RAID array under the Gluster bricks. It looks like 
I'm going to have to rebuild the RAID array and thus likely lose the Gluster 
configuration that lives there. The host OS (oVirt Node) is fine and it's just 
the Gluster/RAID piece that is affected. 

Can one of you please point me to the best documentation link to the process of 
re-configuring that failed node to be identical to the rest of the nodes please 
? It's configured for replica-three and I don't want to have a problem with 
nodes 2 and 3 before I get node 1 back up and healthy.

Any help will be greatly appreciated.

[ovirt-users] Manually Remove Snapshots

[Clint Boggio]

I've got a VM with a pair of snapshots that won't delete and I'm needing a 
procedure to manually remove the snapshots. I don't need the VM and so while 
i'd prefer not to destroy it, it wouldn't be critical if I did damage the VM in 
the process. When I try to delete the snapshots that procedure fails, and when 
I try to delete the disk that procedure fails. Any pointers would be greatly 
appreciated.

[ovirt-users] Cannot Log Into Newly Deployed Hosted Engine

[Clint Boggio]

I have a fresh installation of a 4.5.1 hosted engine and the admin password I 
set during the process isn't working. I reset the password for the admin user 
from a root shell on the HE using the 
ovirt-aaa-jdbc-tool utility and still no dice. I found a log file for 
"keycloak" that I tailed while logging in and discovered that keycloak was 
denying me. I am not familiar with keycloak at all. It appears as though I 
enabled keycloak during the deployment.

Just a few quick answers may get me back to where I need to be:

1. How do I log into the web management portal ? Previously it was 
admin@internal and then the password
2. If keycloak is looking for some kind of directory server outside of the 
engine I don't have one, if the engine is the keycloak server what are my 
credentials for the HE portal ?
3. Can I re-run engine-setup and turn Keycloak off so that I have internal 
based authentication ?

[ovirt-users] Re: HCI Deployment oVirt 4.5

[Clint Boggio]

Thank you very much for the tip. I was able to successfully deploy the engine 
appliance on the gluster configuration that I deployed previously from the 
cockpit interface.

I cannot log into the management portal via username and password and it 
appears as though keycloak is the culprit.

I'll open another thread for that problem. 

Thank you again for your help.

[ovirt-users] Re: HCI Deployment oVirt 4.5

[Clint Boggio]

Today I reloaded all three nodes with the 4.5.1 ovirt node appliance iso. 
During the install I used the gui to bond the two 10gig interfaces using the 
recommended naming convention. I prepped the nodes according to the 
documentation and invoked the cockpit installation method from node1. The 
gluster portion of the hyperconverged deployment went well. When the gluster 
portion of the deployment was finished I proceeded to the hosted engine 
deployment phase in the cockpit environment. The system immediately threw that 
same interface error.

[ovirt-users] Re: HCI Deployment oVirt 4.5

[Clint Boggio]

I did use classic bonding and not teaming. I'm trying to install hyperconverged 
three node oVirt cluster with self hosted engine. I've done it before in the 
4.3 world but not in the 4.4 or 4.5 world.

I'm using the cockpit method for deploying the cluster from the first node from 
the documentation. Should I reload the nodes and create the bonds from the 
nmcli command line instead of from the installation gui ?

"No valid network interface has been found

However I am using a supported naming convention. I've searched the forums and 
the general WWW and read the articles that match my errors. i've tried some of 
the options that are referenced in the articles but still no forward motion.

Is this a common problem that somebody else has already solved and I just am 
not finding it on the web ?

[ovirt-users] HCI Deployment oVirt 4.5

[Clint Boggio]

Hello oVirt Team

I'm in the process of deploying a three-node oVirt hyperconverged platform and 
from the cockpit interface of the deployment node I keep running into the same 
error. The system finishes the gluster deployment phase (sometimes) and then 
prompts to continue with the hosted engine deployment but then fails 
immediately complaining about the naming convention of my network interfaces. 
My network interfaces are 802.3ad bonds configured during the installation 
process of each node using "bondx" naming convention consistent across all 
three nodes. Any wisdom or pointers would be appreciated.

[ovirt-users] Preferred RHEL Based Distro For oVirt

[Clint Boggio]

Good Day All;

i am inquiring about which RHEL based distros are currently preferred and which 
ones are currently supported. I know the oVirt project is a RH entity and so 
RHEL and CentOS-Stream are the base offering. Would it, or is it, feasible for 
Rocky 8.X, or Alma 8.X to be the base OS for an oVirt deployment seeing as 
though they both RHEL clones ?

How confident is the user community in the stability of CentOS-Stream in terms 
of production use as compared to Alma or Rocky ?

[ovirt-users] Dedicated Migration Network

[Clint Boggio]

Good Day All;

I am in the process of assembling a new oVirt cluster and I am wondering if 
there is any benefit to having a dedicated set of nics solely dedicated to VM 
migration. If so, would those nics (bonded) be on their own vlan and subnet or 
would they share a subnet with gluster storage or the management network ? 
Right now i'm planning on the following architecture.

1. Management = 10G X2 Bond per hypervisor host (10.66.0.0/24)
2. Gluster/iSCSI Storage = 10G X2 Bond per hypervisor host (10.244.0.0/24)
3. VM Production Network(s) = 10G X2 Bond per hypervisor host (No IP Range)
4. ?? Possible Dedicated VM Migration

Thank you very much as any input would be greatly appreciated

[ovirt-users] HCI Cluster Configuration

[Clint Boggio]

Ovirt 4.3.9
HCI Gluster 3 Dell 730XD
Managed Engine

When I finished the "hosted engine deploy" I failed to add the gluster
storage according to the documentation and i'd like to get that back on
track.

1. I ticked the check box in the cluster configuration to "enable gluster
service", all of my current gluster storage domains went "red triangle" on
me and the hosts also went "red triangle" so I quickly changed it back and
all went back to normal.

Do I need to check that box to make the "Use Managed Gluster Volume" check
box and drop down menu show my HCI gluster volumes that exist on the three
nodes ?

Do I need to put the storage domain(s) in maintenance mode to change them
from unmanaged to managed ?

Will the system honor the VM(s) that live in my "engine" and "vmstore"
gluster volumes which are currently in use in the system if/when I change
them from unmanaged to managed,or will the system wipe them and hose my
managed engine and VMs ?


Thank you for your help !

[ovirt-users] Cannot Activate iSCSI Storage Domain After Errors

[Clint Boggio]

Good Day To all;

oVirt 4.3.4.3-1.el7
6 Dell R710 oVirt Nodes
10 gig Infiniband iSCSI
Standalone Engine

After an error during scheduled automated VM backkup, the iSCSi datastore that 
the VMs beinng backed up lived on suddenly went inactive and refuse to activate.

The backup job did not finish as the source datastore went inactive but the 
task did clear from the console after i restarted the ovirt-engine service.

I have tried:

1. Restart the ovirt-engine service
2. Restarted the engine physical server.
3. Tried to migrate the VM disks to a different datastore (failure)

The virtual machines that are currently living on the inactive datastore are 
still running and accessible.

Trying to reboot one of those VM as a test fails as the VM will not come up due 
to the system believing that the datastore is inactive.

From engin.log:

[ovirt-users] VM With Snapshots Marked As Illegal

[Clint Boggio]

Greetings oVirt Users;

Environment:

oVirt 4.2.0.2-1
1 Dedicated Engine
6 Hypervisor Nodes
iSCSI Storage
All running CentOS 7.5

I have a VM with the illegal snapshot error. After doing some research
on the condition i have found some methods for fixing the problem by
connecting to the database and repairing the fault. I am unable to
connect to the engine database from the engine command line with the
password in 10-setup-database.conf for whatever reason. (likely user
error)

I don't really need the disk that is attached to this VM that is at
fault as it is a disk that is being utilized by the VM to perform local
backups and that function has been moved to an offsite backup solution.

If I shut down the afflicted VM, then delete the un-needed disk, will
the snapshots be deleteed and thus the problem alleviated ?

Or will the system not delete the un-needed disk because of the fault
and then not reboot because if the illegal statu of the snapshot ?

I have tried to delete the snapshots, and the system refuses to do so.

I may need some guidance regarding connecting to my engine database if
i cannot delete the un-needed disk.

Thank you all for any help in this matter, and if more information is
needed please let me know.

Re: [ovirt-users] newbie questions on networking

[Clint Boggio]

You should query the network to team for sure.

You should also use use the ping command (from the VM) to troubleshoot possible 
MTU problems getting to your infrastructure DNS servers and gateway.

# ping -M do -s 1472 xxx.xxx.xxx.xxx

Starting at 1472 and “walking” the -s up and down will help you determine your 
situation.

If at all possible, you could take the production switches and gateway out of 
the equation with your own isolated gear.

Randy this flaky layer two problem reeks of a possible MTU situation between 
your oVirt switches and your physical switches.

[ovirt-users] Cluster Processor Change

[Clint Boggio]

Forgive me if this is a duplicate, as I had spam filter problems previously 
when I sent this inquiry.

Environment Rundown:

OVirt 4.2
6 CentOS 7.4 Compute Nodes Intel Xeon
1 CentOS 7.4 Dedicated Engine Node Intel Xeon 
1 Datacenter 
1 Storage Domain
1 Cluster
10Gig-E iSCSI Storage 
10Gig-E NFS Export Domain
20 VM’s of various OS’s and uses 

The current cluster is using the Nehalem architecture.

I’ve got the deploy two new VMs that the current system will not allow me to 
configure with the Nehalem based cluster, so I’ve got to bump up the 
architecture of the cluster to accommodate them.

Before i shut down all the current VMs to upgrade the cluster, I have some 
questions about the effect this is going to have on the environment.

1. Will all of the current VM’s use the legacy processor architecture or will I 
have to change them ?

2. Can I elevate the cluster processor functionality higher than the underlying 
hardware architecture  ?

3. In regards to the new cluster processor, will all of the processor 
architectures below the one I choose be an option for the existing and future 
VMs ?

I apologize for the long post and I hope that I haven’t left out any vital 
information.

Re: [ovirt-users] VM Disks Locked

[Clint Boggio]

Well Brett that's not totally out of the question however I'd prefer not to. 
I've seen other threads whereby there was a database command to locate the 
problem, and then a command to take that information and solve the problem.

This system is very much in production and I'd like to avoid poking it with a 
stick lol.

That is correct. We are successfully using ib0 to access iSCSI and NFS on all 
nodes.

We are now trying to create a network for the VMs to use on ib1.

Re: [ovirt-users] Adding Infiniband VM Network Fails

[Clint Boggio]

That is correct. The ib0 in all of the HV nodes are accessing iSCSI and NFS 
over that IB link successfully.

What we are trying to do now is create a network that utilizes the second IB 
port (ib1) on the cards for some of the virtual machines that live inside the 
environment.

[ovirt-users] 3.6 to 4.0 Functionality Elevation

[Clint Boggio]

Greetings OVirt Community

I have a production system that started life as a OV 3.6 system, and I've 
recently upgraded the engine to 4.0. I see in the cluster config, a 
configuration element that indicates the cluster functionality level. It has a 
drop down that allows me to toggle between 3.6, and 4.0.

If I select 4.0 and save, what potential problems could I expect ?

Setup;

1 Dedicated engine CentOS7 OV version 4

6 hosts running CentOS7 and OV version 4.0 and 3.6 repos.

Main data domain is iscsi over IB.

ISO and all other data domains are  NFS over IB

beautifully.

I should have checked that  first and i apologize. Thank you for your
help.

[ovirt-users] Dashboard Never Loads

[Clint Boggio]

Greetings ovirt community;

I have an oVirt environment with a dedicated engine, and 4
compute nodes all running CentOS 7, and oVirt 4.0.1.1. On the
management interface, the "Dashboard" tab displays "Loading" and the
spinning applet is working hard, but nothing ever materializes on the
screen. I aplogize if this has apready been addressed, and i searched
deeply before I decided to ask the forum.

Is there a document on troubleshooting this problem ?

Re: [ovirt-users] Management Engine Down

[Clint Boggio]

Thank you both for your help in this matter.

I did alleviate 95% of the problem by removing the old ldap authentication 
method, and successfully upgrading the engine to 4.0. Upon completion the 
engine did start and all is well.

AD authentication is currently broken due to my own ignorance as to which 
option to choose when running the new tool. This is not a huge problem and I 
will work through it. I may need some hand holding regarding the aaa setup, but 
I'll ask after I've read the documentation and failed to complete the task.

Thank you again for your willingness to help.

[ovirt-users] Management Engine Down

[Clint Boggio]

Stand Alone Engine Version 3.6.X
CentOS 7

I was preparing to upgrade from OME 3.6.2 to 4.0, when I followed the systems 
instructions to "migrate" to ovirt-engine-aaa-ldap authentication from the 
current authentication method. The management engine did fail to restart after 
the process with the following excerpt from "journalctl -xe" Any help or advice 
would be most appreciated.

[ovirt-users] iSCSI Data Domain Down

[Clint Boggio]

Greetings oVirt Family;

Due to catastrophic power failure, my datacenter lost power. I am using a 
CentOS7 server to provide ISCSI services to my OVirt platform.

When the power came back on, and the iscsi server booted back up, the filters 
in lvm.conf were faulty and LVM assumed control over the LVM's that OVirt uses 
as the disks for the VMs. This tanked target.service because it claims "device 
already in use" and my datacenter is down.

I've tried several filter combinations in lvm.conf to no avail, and in my 
search I've found no documentation on how to make LVM "forget" about the 
volumes that it had assumed and release them.

Do any of you know of a procedure to make lvm forget about and release the 
volumes on /dev/sda ?

OVirt 3.6.5 on CentOS 7
4 Hypervisor nodes CentOS7
1 Dedicated engine CentOS7
1 iscsi SAN CentOS 7 exporting 10TB block device from a Dell Perc RAID 
controller /dev/sda with targetcli.
1 NFS server for ISO and Export Domains 5TB

I'm out I ideas and any help would be greatly appreciated. 

I'm currently using dd to recover the VM disk drives over to the NFS server in 
case this cannot be recovered.

[Bug 1329000] Snapshot Images Flagged as "ILLEGAL" After Backup Script Is Run


Is there a technique for recovery from this condition or should I back up the

Re: [ovirt-users] Disks Illegal State

[Clint Boggio]

In my case Markus, the backing disks are MIA and show only as bright
red broken symbolic links. Using the postgres commands to set them as
OK would be folly, and likley cause more trouble. if the snapshot disks
are truly gone, (and they are), what procedure would i use to inform
the database and set the VM's in a usable status status again ?

The below output is an excerpt from the engine.log while attemtping to start 
one of the afflicted VM's. Following the storage chain out i have discovered 
that "919d6991-43e4-4f26-868e-031a01011191" does not exist. This is likely due 
to a failure of the backup python script that the client is using. I can 
provide that script if you all would like.

I have followed the storage chain out to where the UUID'ed snapshots live, and 
discovered that all of the "ILLEGAL" snapshots show to be broken symbolic links.

Attached is a screenshot of the snapshots as they appear in the GUI. ALL of the 
UUID's illustrated show as broken symbolic links in the storage domains.

[ovirt-users] Disks Illegal State

[Clint Boggio]

OVirt 3.6, 4 node cluster with dedicated engine. Main storage domain is iscsi, 
ISO and Export domains are NFS.

Several of my VM snapshot disks show to be in an "illegal state". The system 
will not allow me to manipulate the snapshots in any way, nor clone the active 
system, or create a new snapshot.

In the logs I see that the system complains about not being able to "get volume 
size for xxx", and also that the system appears to believe that the image is 
"locked" and is currently in the snapshot process.

Of the VM's with this status, one rebooted and was lost due to "cannot get 
volume size for domain xxx".

I fear that in this current condition, should any of the other machine reboot, 
they too will be lost.

How can I troubleshoot this problem further, and hopefully alleviate the 
condition ?

Thank you for your help.

[ovirt-users] Single VM Down After Attempted Snapshot

[Clint Boggio]

Greetings users;

I've got a single VM in a 3.6 environment that is in a down state after
and attempt at creating a snapshot via script, and  exporting said
snapshot to the export domain. I see some indications of what could
possibly be wrong in the filtered engine.log, and i'm at a loss on how
to repair the problem. Below is a "tailf" of the engine.log as i attempt
to run the VM in it's current state. Any guidance or wisdom would be
much appreciated.

[ovirt-users] Storage Diversity Options oVirt 3.6

[Clint Boggio]

Greetings all, and Happy Friday;

I'm running oVirt 3.6 management engine that is currently overseeing 4
compute nodes, attached to iSCSI storage over Infiniband. The compute
nodes have 8 hot-swap hard drive slots, with each only having 2 slots
occupied in a hardware RAID array level one for the hypervisor to live
on.

Would it be possible for me to set up each compute node with a second
array in the remaining 6 hot-swap slots, and utilize that new space for
a nice fault tolerant GlusterFS storage array ?

1. Would the system allow me to add the Gluster storage to the existing
datacenter/cluster that is currently using iSCSI ?

2. Would I be able to configure all aspects of the Gluster
environment(except the hardware RAID array)through the GUI ?

3. What hardware RAID level would be optimal for  this configuration ?
(RHEV documentation says RAID 6 is "Mandatory")

4. Will the system support live migration between storage domains ?

I'm reading through the gluster documentation now to get a better
understanding of it's inner workings. Is there a good source for Gluster
on oVirt that i can reference as well ?

That worked like a charm. I'll add that to my cheat sheet.

 I had a keyboard problem and entered the wrong password for admin@internal 
enough times to finally lock the account.

[ovirt-users] Promiscuous Mode

[Clint Boggio]

I am deploying an OpenVPN server in my OVirt environment and I've come to a 
dead stop with the developer support on a topic related to OVirt configuration.

The developer wants me to put the VM's underlying NIC into promiscuous mode.

I've seen this in a VMware environment and I know what they are asking me to 
do, and I'm wondering if there is a clear way to do this in my OVirt 
environment.

I found "port mirroring" but no "promiscuous mode"

Cheers and thank you !

Re: [ovirt-users] virt-v2v converting multi-disk

[Clint Boggio]

Thanks Rich for the clarification and thanks Moran for getting me to the right 
human :-)

I'll be searching for the import feature tomorrow after I build out the main 
storage domain and the datacenter goes green.

I REALLY appreciate all you guys do, and the help you provide.

I've tried the -i libvirtxml method and it fails and I suspect it's because the 
legacy KVM environment is Ubuntu based. Any tricks or pointers would be 
appreciated.

I typically scp the VM image file to the root of the export domain and use the 
-i  method because of the limitation of Ubuntu.

Thank you again

[ovirt-users] virt-v2v converting multi-disk

[Clint Boggio]

I'm in the process of migrating a series of VM's from  KVM environment, to an 
OVirt environment. I've used virt-v2v to convert quite a few M$ and Linux 
machines with great success.

Coming up I've got to convert a Linux VM that has 3 virtual disks. Inside that 
VM, the three disks are part of an LVM volume.

1. How will virt-v2v handle these three virtual disks ?
2. On which disk image will I run virt-v2v ?
3. Will virt-v2v "follow" the three images and convert the machine or will I 
have to somehow tell it to include all three disks ?
4. Shall I have all three images together in the same directory when I run the 
tool ?
5. Is this the appropriate forum for this question ?

As of the writing of this question I'll be using OVirt 3.6 updated on a 4 node 
cluster running CentOS 7 , and the most recent version of virt-v2v as is 
available on Fedora 23.
