[ovirt-users] Re: lvcache on partitioned ssd or only on full device?

[okok102928]

Is this right?
1. Define the area where the Hypervisor OS will be installed on the SSD Raid1
2. Partition the disk
3. Using lvm as part of gluster brick cache

If what I understand is correct, configuration is possible but not recommended.
When the volume has a lot of I / O, it can cause problems with the hypervisor. 
(Response delay, etc.)

I have shed blood sweat & tears.

If you want to use lvcache, be sure to use a separate flash disk.
Never use NVMe. It has its own limit (bottleneck) and does not enjoy the 
benefits of nvme.

[ovirt-users] Storage domain mount error: Lustre file system (Posix compliant FS)

[okok102928]

Hi.
I am an ovirt user in Korea. I am working on VDI. It's a pleasure to meet you, 
the ovirt specialists.
(I do not speak English well... Thank you for your understanding!)

I am testing Lustre File System in Ovirt or RH(E)V environment.
(The reason is simple: glusterfs and nfs have limit of performance, SAN Storage 
and excellent Software Defined Storage are quite expensive.)

Testing for file system performance was successful.
As expected, luster showed amazing performance.
However, there was an error adding luster storage to the storage domain as 
Posix compliant FS.


Domain Function : Data
Storage Type : POSIX compliant FS
Host to Use : [SPM_HOSTNAME]
Name : [STORAGE_DOMAIN_NAME]
Path : 10.10.10.15@tcp:/lustre/vmstore
VFS Type : lustre
Mount Options : 

The vdsm debug logs are shown below.

[ovirt-users] lvcache on partitioned ssd or only on full device?

[guillaume . pavese]

Hi,

If possible, I would like to configure a hyperconverged cluster with hosts' 
system partitions and the gluster's lvcache on partitions of SSDs in RAID1.
Is it possible to define the lvcache on a partitioned device like /dev/sdaX ; 
or is it only supported to pass a whole device like /dev/sdb ?

Thanks for your help

[ovirt-users] Newbie Ovirt 4.2 - hosts all fail installs

[nuno]

Hi - I have just setup 3 hosts and I am running a self hosted engine on the 
primary host - I am now trying to add the remaining two and my installs take 
awhile and then fail.

Logs say ssh timeout, but the engine can get to the systems via DNS or hosts 
file etc - 

Any advice ? 

Thanx guys,


So i have 3 servers and i am running Ovirt 4.2 with a self hosted engine on the 
primary host. I am trying to add the other hosts but keep getting failed 
installs due to ssh timeouts - The engine can get to the hosts via DNS and via 
hosts files but the install just bombs.


Any advice ?  - i have added some of the engine.log to this mail -- 
Unfortunately Martin who works on this side of things is overseas training, so 
I am abit stuck 


Im trying to show dstv this setup so we can move them off the fusionSphere and 
move to RHEV

[ovirt-users] Tutorial for beginners:: oVirt - how to add 2nd (DMZ) net interface for VMs

[Andrei Verovski]

Hi,


I made another short video tutorial (slide show with screenshots and 
instruction) for beginners.


Explains how to add additional network interfaces (e.g. DMZ) to virtual 
machines running under oVirt/KVM.


https://youtu.be/ij4uMv9N1wo

Best when viewed in full-screen mode at 1080p resolution for clear text 
on screenshots.


with best regards

Do I need to install the matching version of ovirt node?

 

“using it interactively without manually filing an answerfile” – if you mean 
using command: hosted-engine –deploy 

and then manually typing each value, I tried this (choosing the static IP 
option) and the usual error occurs.  I attach the log from this attempt.

 

The issue here is that it seams that your VM never got an address from libvirt 
default network DHCP:

Can you please share the output of

Are you running nested on a different hypervisor?

Hi Simone,

 

I attempted to use a fixed IP address instead of DHCP.  I attach an attempt 
using answer-file parameter:

OVEHOSTED_VM/cloudinitVMStaticCIDR=str:10.0.0.109/24   

which is in accordance with this example on your website:

https://ovirt.org/develop/release-management/features/integration/heapplianceflow/

 

However, instead of this, you will notice that the log has:

OVEHOSTED_VM/cloudinitVMStaticCIDR=bool:'False'

 

The same error as usual occurred.  Is this:

1.  The wrong syntax\format for specifying a “cloudinitVMStaticCIDR” IP?
2.  ovirt setup is ignoring it: either failing to assign the IP to the 
engine VM or to variable “local_vm_ip.stdout_lines”?
3.  Something else?

 

“You can also connect to that VM with VNC to check what's going on.” – Doesn’t 
work.  Port querying 10.0.0.109 on 5800\5900 fails, so I don’t think the VM is 
networked.  Which port does engine VNC use?

 

Many thanks,

OK,

according to this log file, the target engine VM didn't got an IPv4 address:

 

 

 

Are you sure that your DHCP server is properly working?

You can also connect to that VM with VNC to check what's going on.

Hi Callum,

I took a look at this, but got in the weeds pretty quickly with squid 
configuration. I can help more offline, but it might be a while.

It'll probably be easier if you can provide me exact steps for how I could 
reproduce. Looks like I need to generate some keys. Can you create and share a 
simple reproducer?

The issue here is that it seams that your VM never got an address from
libvirt default network DHCP:

Can you please share the output of

Are you running nested on a different hypervisor?

[ovirt-users] clear tasks from WebUI

[David David]

Hi
oVirt 4.2.5.2-1.el7
 I tried to delete an Illegal vm disk and that failed. Then I completely remove
the VM who had that broken disk. But task is stuck in the WebUI from my
previous disk deletion attempt
vdsm-client Host getAllTasksInfo on the SPM host, shows no tasks.
How do I clear the tasks from the WebUI?

[ovirt-users] Re: Adding local block storage

[Tryfon Farmakakis]

Yes, I have seen this guide. So my understanding is that you can add local 
storage either through iSCSI, or through a local filesystem (this is the 
storage directory you are referring to). There is no way to add a directly 
attached block device (eg /dev/sdb). Is this correct?

[ovirt-users] Re: Adding local block storage

[Lucie Leistnerova]

Hi, guide for adding local storage is here:

https://www.ovirt.org/documentation/admin-guide/chap-Storage/#preparing-local-storage

I guess that main problem is the directory you want to add as storage:

*Important:* On oVirt Node, the path used for local storage must be 
within the /var directory; create the storage directory in the following 
procedure within |/var|.

[ovirt-users] REST API on Engine

[Vrgotic, Marko]

Dear oVirt team,

My project with the company for Operations is a success and department is 
successfully using oVirt 4.2.6 (started with 4.2.0 this January) platform with 
SHE and 12 Hypervisors, hooked to GlusterFS distributed-replicated, managed 
outside of oVirt. It is used for Support of Customers, Projects and Trainings.
Thank you oVirt community for such a great platform.
In fact, if it going so well that now I have the task to build new platform for 
Development/Engineering.

Since the users foot print is going to grow from 10 to 80 or 120, plus all the 
automated testing, I am wondering is there a way to make REST API of the Engine 
in HA/LB mode.
For the other services, that is purpose of SHE and DB can always be in 
clustered mode, but I currently need information if there is something I can do 
in this direction for REST API.

Kindly awaiting your reply.

Hi, I have a 4.2 ovirt installation with the ovirt engine on one physical host
