[ovirt-users] Modify the MacPoolRange : Former MACs?

[Nicolas Ecarnot]

Hi,

I plan to extend the MacPoolRange.

If I also completely change the pool, in a way that does not implies the 
previous setting, will the manager ban all the previous MACs, now 
outside the defined pool? (and stop the VMs?)


Regards,

Re: [ovirt-users] Passing custom script to cloud init using api

[Shanil S]

Hi Juan,

What i am planning to do is to make work the following script

#cloud-config

# phone_home: if this dictionary is present, then the phone_home
# cloud-config module will post specified data back to the given
# url
# default: none
# phone_home:
#  url: http://my.foo.bar/$INSTANCE/
#  post: all
#  tries: 10
#
phone_home:
 url: http://my.example.com/$INSTANCE_ID/
 post: [ pub_key_dsa, pub_key_rsa, pub_key_ecdsa, instance_id ]

(
http://cloudinit.readthedocs.org/en/latest/topics/examples.html#run-commands-on-first-boot
)

but it wasn't working when i tried, i hope to post the above values to the
specific url and get the posted details.

Hi Juan,

Okay.. Thanks.. its working.

I would like to execute other page something like test_script.php by
posting some values to it using the cloud init, Is it possible to do it ?

[ovirt-users] Reachability problems after putting ovirtmgmt and Gluster on different networks

[Stefano Stagnaro]

Hi, I have a question about an HostedEngine deployment. I followed the Jason's 
"oVirt 3.4, Glusterized" and it seems working. I've two host for virtualization 
(that also do the HA for the HostedEngine) and two other host for GlusterFS.

Now I would like to configure separate networks for the management and Gluster. 
On my Catalyst I've configured two VLANs with two different default gateways. 
My aim is to add the Gluster hosts with the IP of the "ovirtmgmt" and then add 
the storage domain pointing to the same host but using the IP of the "Gluster 
network".

Unfortunately, the HostedEngine has only one nic (on ovirtmgmt) and so I'm not 
able to reach the Gluster host with his "Gluster network" IP even if the 
L3-switch has all the networks configured. Reading this article 
http://brainscraps.wikia.com/wiki/Setup_Gateway_Routing_On_Multiple_Network_Interfaces
 I believe the problem is on the Gluster host that only has the ovirtmgmt 
gateway.

I've found out that someone has tried to add a second nic on the HostedEngine 
by editing the /usr/share/ovirt-hosted-engine-setup/templates/vm.conf.in 
"template" prior to start the deployment.

My question is: there is a better way to achieve this (I'm missing something 
for sure)? Is it worth having the ovirtmgmt separate to the storage? In 
production, I'll have five 1gbps ports per host (that could be bonded as 
preferred).

Thank you,

Do you mean an internal qemu task which is triggered to
extend a thin provisioned disk to the required size?

yes


This process shouldn't permanently pause the VM, right?

no



Or do you mean something else?

You want to use ls -lsh or even ls -lash

keep in mind these are sparse files.

for more information on this topic read the man page for ls

qemu would pause a vm when doing extend on the vm disk and this would 
result in INFO messages on vm's pause.


looks like this is what you are seeing.

Hi,

The vdsm log provides a better error message:

Still, I don't know what exactly caused this. Only *one* VM was affected,
so I doubt it was a general error on this host. Does anyone have an
explanation for this?

The vdsm log provides a better error message:

libvirtEventLoop::INFO::2014-09-09 04:00:07,279::vm::4574::vm.Vm::(_onIOError) 
vmId=`8ad326be-5103-498a-a11d-0ea1eee4bbf4`::abnormal vm stop device ide0-0-1 
error 
libvirtEventLoop::DEBUG::2014-09-09

vmId=`8ad326be-5103-498a-a11d-0ea1eee4bbf4`::event Suspended detail 2 opaque 
None

Still, I don't know what exactly caused this. Only *one* VM was affected, 
so I doubt it was a general error on this host. Does anyone have an 
explanation for this?

Thanks.
But to make use of it (call nmcli con load), Ondrej needs to clone this bug to

Hi,

I'm quite new to ovirt and I'm going to deploy ovirt into several tens
location all around world.

The connection between locations is neither dedicated nor 100% reliable
as it's connected via internet.
I'm going with Gluster storage domains mainly.
It's not important to me to do live migrations or even offline
migrations between locations (they're independent).

What's the best design and components from your point of view? I believe
I'm not the first one with such design.

I think about two possibilities:
1) One central Engine
- how to manage guests when connection drop between engine and node
- latency is up to 1 second is it ok even with working connection?

2) Engine in every location
- is it possible to have also one central point with information
from all engines together (at least read-only)?
- what about central reporting at least?

I like more one central Engine. My concern is how to work with consoles
and also just 1 ISO storage domain and 1 export storage domain (maybe
same hostname for ISO and export in every location). Another topic is
how to reach console/stop/start/migrate guest inside location while
there is connection down between the only Engine and nodes in the
location.

Thanks ahead for you experience/ideas,



we run this with central engine and remote clusters, but remote 
clusters have decent connectivity.


oVirt 3.5 does bring several improvements to fencing management which 
may help those with problematic links.


for option #2 - ManageIQ (upstream of Red Hat CloudForms) is a "CMP" - 
Cloud Management Platform, which can provide overall dashboard, 
self-service, service catalog, automation, etc. across multiple ovirt 
deployments.

(they just released their first upstream release last week)

Using ManageIQ does work but is still more for the management of things 
running on the cloud. In this case you still will have separate ovirt 
environments that you have to manage.


That's not so bad and probably recommendable for a lot of use cases as 
you can't mess up all your DC's with one login.


Also it would be nice to have the frontend running somewhere that 
doesn't have to be on the management lan of all the virtual 
infrastructure and be able to reach even the IPMI's. If you have users 
accessing it, they could hake the management server and have access to 
all nodes in all DC's. You can build another interface with api calls to 
seperate them, but why bother when we already have a user interface.


Also when your connection to the DC's is interrupted you availabillity 
will suffer, but the reason we want to spread our virtual infrastructure 
accross multiple DC's is to remove SPOF of the datacenter.


What we would like to do is have a central datacenter that hosts our 
management infrastructure and is highly secure. When we access this 
management infrastructure, we can then manage all our other racks in 
other DC's through sattelite-systems/smart-proxies. Same like this:




A more distributed ovirt-engine would IMHO make the virtual 
datacenter/cloud infrastructure scale better across locations. While 
ManageIQ does that for multiple clouds. Two different use cases.

_SHA_CKSUM is valid but you can try to remove it (you'll just get warnings
about the missing checksum).

I expect vdsm to try and mount your domain on:

 /rhev/data-center/mnt/10.244.44.200:_exports_ovirt

If that's successful please report the output of these commands:

 # mount
 # ls -lR /rhev/data-center/mnt/10.244.44.200:_exports_ovirt


If instead the share is not mounted please report the mount error that you
find in the vdsm logs.

Re: [ovirt-users] How to change glusterfs volume type for MASTER storage domain

Hi Darell,

Thanks for that. That will work fine for what I'm trying to do.

In a similar situation, I’ve had some luck creating a second storage 
domain & allowing the master role to be moved to it. You don’t even 
need to have any VMs on it, just have it exist and add it to the 
engine. That way ovirt doesn’t freak out and reboot your nodes as much 
while you clean up your main storage domain.

Hi,

Our ovirt test instance has 4 nodes with glusterfs master storage 
domain. I had the volume set to distributed replicated gluster and 
things worked.


Due to quorum issues, I'm trying to switch it to replicated with 
replica count 4.


Currenlty the nodes keep rebooting while the master storage is down 
and I can't get things up again.


Invalid status on Data Center Default. Setting status to Non
Responsive.
Host node3 cannot access the Storage Domain(s)  attached
to the Data Center Default. Setting Host state to Non-Operational.

Is there a known way to change the glusterfs volume for the master 
domain that doesn't end in a total system faillure?

Punit,

 Create that script manually, Refer : 
https://www.mail-archive.com/users@ovirt.org/msg20467.html

or you can simply run ;

#source /etc/ovirt-engine/engine.conf.d/10-setup-database.conf

#PGPASSWORD=$ENGINE_DB_PASSWORD psql -U postgres -d engine -c  "select vm_name, 
image_group_id,image_guid from vm_device,

If you're on 3.4, You will fine the above script at
/usr/share/ovirt-engine/dbscripts location on your ovirt engine
system.

 |Secondly yes i am referring the Template CentOS...every details
i provide you in the previous mail is correct...

show us "qemu-img info" output.
