[ovirt-users] lose my server ovirt-engine in network

2020-11-04 Thread garcialiang . anne 
Hello,
I installed my ovirt-engine during 1 month. I can connect with ssh or website. 
Yesterday, I rebooted my server ovirt-engine. But I can't connect it with ssh. 
My server lost in network. I can login with the machine, but I can't ping with 
network.
Is there the problem with network setting ?

Could you help me, please?

Thanks,

Anne Garcia

I checked the qemu-ga version in Ubuntu 16.04 and it is too old. It is
version 2.5 but you need at least 2.10 for it to work properly with
oVirt. I tried to install the package from Ubuntu 18.04 [1] and it was
without issues. Is that a viable option for you?

Do I understand this correct, is OVirt installing the SSL certificate for the

If I have to install my own SSL for the domain and stored on my servers, can I 
use Let's Encrypt?

Hello,

Good Day!
I'm Hariharan and I'm working as System Administrator in Linux platform for 
RWTH Uniklink - Germany. Currently I'm managing the Ovirt environment and I'm 
very new to this domain. Currently I'm facing an issue with Ovirt self hosted 
engine installation 4.4 in CentOS 8 server.  I have an issue when mounting the 
glusterfs storage to a target machine. Below is the exact issue what I face;

Error: "changed": false, "msg": "Error: the target storage domain contains only 
11.0GiB of available space while a minimum of 61.0GiB is required If you wish 
to use the current target storage domain by extending it, make sure it contains 
nothing before adding it.

Note: (gluster storage was installed and configured in Linux work station with 
adding additional hard disk in one of the two gluster storage linux work 
station. I used replicated volumes (replica 2) in creating gluster volumes)

Hardware detail:
device model: Dell R540
Capacity: 240 GB

I tried best possibilities to resolve this issue but still I'm facing the same 
issue. Could you please help me in resolving this issue with your guidance or 
support.

Hi Dominik, 




I don't have any concerns, I only wanted to know, why it will be removed, 
because it can increase network performance a lot. 

Thank you very much for your explanation. 




I fully understand, that you want to remove features, when nobody is using 
them.

Hi Ales, 

what do you mean with "not maintained for a long time"? 



The oVirt integration of dpdk was not maintained. 

BQ_BEGIN

DPDK is heavily developed and make the linux network extremely fast. 

I don't think, that SR-IOV can replace it, 

BQ_END

The removal of dpdk is about removing the dpdk support from oVirt hosts only. 
We wonder if there is someone using dpdk to attach oVirt VMs to physical NICs. 
We are aware that many users use SR-IOV, especially for scenarios of enabling a 
high count of Ethernet frames for VMs or requiring a low latency, 
but we are not aware of users using dpdk to connect the oVirt VMs to the 
physical NICs of the host. 

BQ_BEGIN

because packets must be still processed by the kernel, which is really slow and 
CPU demanding. 

BQ_END


In SR-IOV the packets might be processed by the guest kernel, not but the host 
kernel. 
oVirt is focused on the host kernel, while the guest OS is managed by the user 
of oVirt. 

Did this explanation address your concerns?

Hello, 
we have decided to remove dpdk in the upcoming version of oVirt namely 4.4.4. 
Let us know if there are any concerns about this. 

BQ_END

Can you give more info why we want to remove this feature, and what is 
the replacement for existing users?

Sure, 
the feature was only experimental and not maintained for a long time. The 
replacement is to use SR-IOV 
which is supported by oVirt. 

Thanks, 
Ales

[ovirt-users] Affinity Group Graceful Migration

2020-11-04 Thread thilburn 
Hello,
 I'm trying to get an Affinity Group setup that will gracefully remove VMs from 
a Host. Below is what I've tried but the VMs will not migrate off.

oVirt 4.3
Priority: 1
VM Affinity Rule: Disabled
Host Affinity Rule: Negative ( Soft )
Virtual Machines: Select a VM ( My understanding is this would mean all VMs? )
Hosts: Host: 

Also, is this right place to ask for help on this?

I'm Hariharan and I'm working as System Administrator in Linux platform for

[ovirt-users] Re: Ovirt 4.4 ilo_ssh version HP ILO3. ERROR: Unable to connect/login to fencing device

2020-11-04 Thread melnyksergii 
Dears,
So, I found solution.
Logically if Ovirt used user vdsm on hosts, and vdsm placed on host I find dir  
/var/lib/vdsm/.ssh
Then I create in /var/lib/vdsm/.ssh file config with strings: 
Host *
  HostKeyAlgorithms=+ssh-dss

And after this actions the test of ssh ilo fence is OK.
I don't know is this solution correct? May be you know another, more correct 
way for solve this problem?
Thanks

[ovirt-users] Ovirt 4.4 ilo_ssh version HP ILO3. ERROR: Unable to connect/login to fencing device

2020-11-04 Thread melnyksergii 
Dears, 
I have a 3 nodes with HP blade servers G7 and ILO3. ILO3 with the latest 
firmware 1.93 from Aug 07 2020. 
I'm try to migrate from Ovirt 4.3 to 4.4 with Centos 8, but I had a problem 
with setup ssh ilo fence on this nodes. In Ovirt 4.3 with Centos 7 all is works.
When I try to Test fence, I see ERROR: Unable to connect/login to fencing 
device.
When I try to use /usr/sbin/fence_ilo_ssh I see the same error.
So, I know where is a problem. The problem in an old ssh security keys  
HostKeyAlgorithms=+ssh-dss.
When I add to /root/.ssh/config some exclude for use HostKeyAlgorithms=+ssh-dss 
I can connect to ilo over ssh from root with: 
/usr/sbin/fence_ilo_ssh -a 10.0.11.157 -l user -p passwordh -x -u 22 
--login-timeout=10 -o status and see:
 Status: ON
But when I try again setup ilo_ssh fence in Ovirt-engine UI I still have the 
same  ERROR: Unable to connect/login to fencing device.
How can I solve this problem in Ovirt?
Thanks

The removal of dpdk is about removing the dpdk support from oVirt hosts
only.
We wonder if there is someone using dpdk to attach oVirt VMs to physical
NICs.
We are aware that many users use SR-IOV, especially for scenarios of
enabling a high count of Ethernet frames for VMs or requiring a low latency,
but we are not aware of users using dpdk to connect the oVirt VMs to the
physical NICs of the host.

In SR-IOV the packets might be processed by the guest kernel, not but the
host kernel.
oVirt is focused on the host kernel, while the guest OS is managed by the
user of oVirt.

Did this explanation address your concerns?
