[ovirt-users] Warning: out of sync hosts ovirt-node3 ?

[wangyu13476969128]

In the ovirt-engine web interface, compute-->clusters,  there is a cluster with 
the following information:
Warning: out of sync hosts ovirt-node3 ?

What is the cause ? How can I solve this problem ?

 Hello,

during the Installation of Windows Server 2019 after the first reboot
the VM crashed and inside the ntbtlog.txt I found that dxgkrnl.sys can
not be loaded.

Environment:
oVirt 4.3.6.7-1.el7
CPU: Intel-Westmere
Memory: 4096MB
Operation System VM config: Windows 2019 x64
HDD: VirtIO-SCSI
VirtIO driver: virtio-win-0.1.171_servers_amd64.vfd

Does anybody has an hint how to solve this problem and use Windows
Server 2019?

Besides: It's possible to install and use Windows Server 2019 in
VirtualBox 6.*. We have to install it in the meantime there to have a
alternative solution because it took now about two days to find a
solution. We tried different settings for VGA and drivers IDE ... and
many more.

[ovirt-users] Re: oVirt change IP's & add new ISO share

[Strahil Nikolov]

 As far as I know , hosts can be changed by:1. Remove a host from oVirt.2. 
Change the IP and reboot to verify functionality3. Add the host to oVirt
For the engine is a little bit more difficult as there is an OVMF file that is 
on the shared storage and the ovirt-ha-broker & ovirt-ha-agent are reading and 
searching for IP/FQDN.
Maybe you can try the following (never tested, just improvising, USE ON YOUR 
OWN RISK!!!):00. Prepare an Engine backup0. Prepare an xml for virsh where 
HostedEngine is booting from an ISO (take the xml from vdsm.log and alter the 
boot order)0. Prepare an xml for the vdsm-ovirtmgmt network. Mine is:
  vdsm-ovirtmgmt
  c3964504-2b11-4605-8236-3ca87d5d54a7
  
  

0. set an alias for virsh:alias virsh='virsh -c 
qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf'

1. Set global maintenance2. Change manually the IP in the engine3. Wait at 
least several hours (default value for update of the OVMF is not working as we 
would like to)4. Power off the Engine5. Power on the engine while still in 
maintenance:hosted-engine --vm-start6. If the Engine comes alive and is treated 
as healthy - you can remove the maintenance and try again via powering off the 
engine from inside the VM.
Note: This will set 'score: 0' for the host that was holding the engine - to 
fix -> set the node to local maintenance and remove the maintenance.P.S.: you 
can set a cronjob on reboot like this:@reboot /usr/bin/sleep 600; /usr/bin/mv 
/root/ifcfg- /etc/sysconfig/network-scripts && /usr/bin/systemctl restart 
network
So if you fail to login over ssh , it might revert your IP change :)


P.S.: if the engine doesn't come up you can:1. Define the network via virsh and 
the network xml from step 02. Define the HostedEngine (you might have to first 
undefine it) with the xml that you took from vdsm.log and manipulated it to 
boot from DVD3. Power the vm in paused state (use hosted-engine)4. Get a 
password for the VNC5. Connect via VNC6. Use virsh to resume the HostedEngine7. 
In rescue mode - revert the IP

Of course if the revert fails - you got the necessary data in step 0 to rescue 
the engine and as last resort you got an engine backup.

Good luck and don't forget to share your experience!

 Hi Pavel
Thank you for the advise, it helped a lot.
Do you have recommendation on changing the IP addresses of the oVirt Engine, 
hosts and storage?
My customer did a SD-WAN setup and there are conflicting IP's, so I need to 
move the oVirt environment to a new IP range.
Thanks

Hi Jonathan,Probably the easiest way is to remove the domain.
Can you try the following:1) Go to "Storage" menu.
2) Go to "Domain" menu.
3) Click on the domain with the red status.4) Destroy it (in your case the 
"Destroy" option should be enabled):

Hope it helps.

[ovirt-users] Re: DHCP Client in Guest VM does not work on ovirtmgmt

[ccesario]

Hi folks,

After several tests and a bit talk with Dominik via IRC, the problem it was 
found.
To sum up, the problem it was in my side, once Im using bonding mode 2 (I read 
in some local that no needed switch config), but Dominik correct me that it is 
needed a config in switch side. After it the DHCP client it worked as expected.

IMHO would be nice, Ovirt support bond0 or nic teaming, like VMware, where in 
some cases there is no needed special config on network/switch side and we 
still have some redundancy and availability.

Thank you all by help.

Regards
Carlos

[ovirt-users] Re: Do I need to use self hosted engine with a GlusterFs three node setup

[Strahil]

I remember creating my oVirt setup in 2 stages:
1. Using cockpit to deploy the gluster cluster
2. Using cockpit to deploy HCI on the created gluster clustet.

If that's not changed you can only deploy the gluster clustet, thrn deploy the 
engine somewhere else and then connect the engine (add storage domain)  to the 
gluster cluster, which also can be your oVirt compute nodes (making them at the 
end HyperConverged oVirt Cluster).

Of course , that was an year ago - so it could be different.

Looking at the bug, the fix was done with $ git tag --contains
12bd5cb1fe7c95e29b4065fca968913722fe9eaa
ovirt-engine-4.3.6.6
ovirt-engine-4.3.6.7
ovirt-engine-4.3.7.0
ovirt-engine-4.3.7.1

So the fix is already included in release oVirt 4.3.6.

[ovirt-users] Re: [ANN] oVirt 4.3.7 Third Release Candidate is now available for testing

[Florian Schmid]

Hello, 

I have a question about bugs, which are flagged as [downstream clone - 4.3.7], 
but are not yet released. 

I'm talking about this bug: 
[ https://bugzilla.redhat.com/show_bug.cgi?id=1749202 | 
https://bugzilla.redhat.com/show_bug.cgi?id=1749202 ] 

I can't see it in 4.3.7 release notes. Will it be included in a further release 
candidate? This fix is very important I think and I can't upgrade yet because 
of this bug.

[ovirt-users] Tesla P4 and /sys/class/mdev_bus/

[Fabrice Bacchella]

I have a Tesla P4 installed on a HPE ProLiant DL360 Gen10 on a CentOS 7.7. The 
setup was running fine since at least February. I made a successful upgrade 
from oVirt 4.2 to 4.3 and CentOS 7.6 to CentOS 7.7. I was using in oVirt in a 
pass-througth setting.

I made a minor upgrade a few days ago. And since the VM is unable to see the 
Tesla P4. I think that the main problem is with mdev. vdsm-client Host 
hostdevListByCaps | grep mdev return nothing. There is no directory 
/sys/class/mdev_bus. I tried a full modload: modprobe nvidia_vgpu_vfio nvidia 
vfio_mdev mdev vfio_iommu_type1 vfio nvidia nvidia-modeset nvidia-drm 
nvidia-uvm vfio-pci. But it does nothing.

Why did my kernel think the P4 is not mdev-compatible any more ? How can I 
check that ? I think it break when upgrading my kernel from 
kernel-3.10.0-1062.1.2.el7.x86_64 to kernel-3.10.0-1062.4.1.el7.x86_64.

I tried with both the nouveau driver and the nvidia driver.___

[ovirt-users] Re: Do I need to use self hosted engine with a GlusterFs three node setup

[donagh . moran]

Hi Vojtech 

Thanks for the info, I have been looking for a method of creating the gluster 
cluster via cockpit on one of my three hosts but the only way I can see is via 
the hosted engine setup. Is it a case that we need to configure the hosts to 
use gluster storage with the cli commands prior to adding it to a pre-existing 
non hosted engine?

yes, this is definitely possible, you can create Gluster storage domain and 
use it no matter there your engine runs

As you did a full backup including the data warehouse you need 

engine-backup --mode=restore --file=file_name --log=log_file_name 
--provision-db --provision-dwh-db --restore-permissions 

see 
https://www.ovirt.org/documentation/admin-guide/chap-Backups_and_Migration.html 



Also: 

1. for reference, you can check 'engine-backup --help'. It should always be the 
most up-to-date documentation. 

2. Since 4.3, almost all options have defaults, see this RFE, and especially 
the comment I now added there:

Subject: [ovirt-users] restore 
Hi, 

I did a backup of engine like this 
# engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name 

In a newly installed machine try to restore it: 

# yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm 
# yum update 
# yum install ovirt-engine 
# engine-backup --mode=restore --file=file_name --log=log_file_name 
--provision-db --restore-permissions 

but get this error: 

Start of engine-backup with mode 'restore' 
scope: all 
archive file: file_name 
log file: log_file_name 
Preparing to restore: 
- Unpacking file 'file_name'

Provisioning PostgreSQL users/databases: 
- user 'engine', database 'engine' 
Restoring: 
FATAL: Can't connect to database 'ovirt_engine_history'. Please see 
'/usr/bin/engine-backup --help'. 

I'm running ovirt Version:4.3.4.3-1.el7 

If I run 
# engine-backup --mode=restore --file=file_name --log=log_file_name 
--provision-db --no-restore-permissions 
still the same error 

Any idea? 

Many Thanks
