Re: [ovirt-users] Recommended Ovirt Implementation on Active-Active Datacenters (Site 1 and Site2) - Same Cluster

Hi oVirt Masters !!!
I create Affinity Rules with sucess using REST API as Martin Sivak wrote on
https://www.ovirt.org/blog/2016/07/affinity-labels
I only want to tell him ( and all others users ) that the URL to check on
his blog is not right ( or at least nomore ).
Wrong way : ( Do not list hosts on affinitylabels - Original as wrote on
Martin Blogs - $ cengine -f
http://localhost:8080/ovirt-engine/api/affinitylabels | jq -r
'.affinity_label[] | {id, name, vms, hosts}')
[root@hlg-rbs-ovirt01-poa ~]# cengine -f
https://hlg-rbs-ovirt01-poa.rbs.com.br/ovirt-engine/api/affinitylabels
{
"affinity_label" : [ {
"read_only" : "false",
"name" : "DATACENTER_TV",
"href" :
"/ovirt-engine/api/affinitylabels/37f59ae4-2c63-46ac-a126-aa75b5be3437",
"id" : "37f59ae4-2c63-46ac-a126-aa75b5be3437",
"link" : [ {
"href" :
"/ovirt-engine/api/affinitylabels/37f59ae4-2c63-46ac-a126-aa75b5be3437/hosts",
"rel" : "hosts"
}, {
"href" :
"/ovirt-engine/api/affinitylabels/37f59ae4-2c63-46ac-a126-aa75b5be3437/vms",
"rel" : "vms"
} ]
}, {
"read_only" : "false",
"name" : "DATACENTER_CORP",
"href" :
"/ovirt-engine/api/affinitylabels/cecf7ac2-3128-443a-8d90-26f90bfca99d",
"id" : "cecf7ac2-3128-443a-8d90-26f90bfca99d",
"link" : [ {
"href" :
"/ovirt-engine/api/affinitylabels/cecf7ac2-3128-443a-8d90-26f90bfca99d/hosts",
"rel" : "hosts"
}, {
"href" :
"/ovirt-engine/api/affinitylabels/cecf7ac2-3128-443a-8d90-26f90bfca99d/vms",
"rel" : "vms"
} ]
} ]
For me the right way are :
[root@hlg-rbs-ovirt01-poa ~]# export
DATACENTER_CORP=cecf7ac2-3128-443a-8d90-26f90bfca99d
[root@hlg-rbs-ovirt01-poa ~]# cengine -f
https://hlg-rbs-ovirt01-poa.rbs.com.br/ovirt-engine/api/affinitylabels/
$DATACENTER_CORP/hosts
{
"host" : [ {
"href" :
"/ovirt-engine/api/hosts/f527f077-dd27-46d2-bd39-3f157177277e",
"id" : "f527f077-dd27-46d2-bd39-3f157177277e"
}, {
"href" :
"/ovirt-engine/api/hosts/f9c9d929-b460-4102-bb29-de1e6ad6ad72",
"id" : "f9c9d929-b460-4102-bb29-de1e6ad6ad72"
}, {
"href" :
"/ovirt-engine/api/hosts/02ead14e-0208-4a74-b1c2-4c19383820f9",
"id" : "02ead14e-0208-4a74-b1c2-4c19383820f9"
}, {
"href" :
"/ovirt-engine/api/hosts/ffde7cb6-30db-4d77-872d-ef4e1b3d1a8e",
"id" : "ffde7cb6-30db-4d77-872d-ef4e1b3d1a8e"

} ]
I am using oVirt 4.0.6.
Thanks.

Affinity labels [1] will allow you to label the hosts and vms to
site1 and
site2 and that should be it.
- create label per site
- add the redpective label to each vm and host
Unfortunately there is no UI for that but with SDK or rest it's easy

Hi Ovirt Jedi´s !!!
First of all, congrats about the product !!! I love Ovirt !!!
I am using Ovirt 4.0.4 with 10 hosts and 58 virtual machines on two
Active-Active Datacenters using two EMC Vplex + two EMC VNX5500 + eight
Dell Blades + 8 Dell PowerEdge M610 and two M620 Servers.
Half servers are on Site 1 and Half servers on Site 2. The same with VMs.
All Sites work as one and have redundant network, storage, power, etc etc
etc ...
I want to know what is the best way to set that VM number 1 runs on Site 1
and VM number 2 runs on Site 2 ?
On Vmware 5.1 we use DRS Group Manager and on Hyper-V we use Custom
Properties on hosts and on VMs. What we use on oVirt without segregate on
two different Datacenters or two different clusters ?
Thanks in advance.
