Single-Host Hyperconverged set-up not showing gluster volumes
by Guillaume Pavese
Hi,
I setup a new oVirt hosted engine instance on a mono-server DC/Cluster;
I deployed gluster on the Hypervisor with cockpit and then the hosted
engine with hosted-engine --deploy
It seems to be working, but IO perfs are not good (10MB/s) on a 4x SAS
disks raid5.
So I wanted to check if the optimize for virt-store settings had been
applied (I remember that there used to be a bug for at least most of 4.2.x)
However, event if I see the data domains in "Storage >> Storage Domains"
and in
"Storage >> Data Centers", "Storage >> Volumes" is empty.
Is that normal? Any idea if there is anything to do to see the gluster
volumes there and manage theirs options?
Best,
Guillaume Pavese

Ovirt dpdk
by lifuqiong＠sunyainfo.com
Hi all,
I noticed that dpdk is experimental support in ovirt 4.2, is it support officially in later version?
And what's the shortage or insufficient of dpdk in ovirt 4.2?
Thank you!

Re: disk snapshot status is Illegal

The vdsm logs are not the correct ones.
I assume this is the failure:

As well as `virsh -r dumpxml ind-co-ora-ee-02` (assuming ind-co-ora-ee-02
is the VM with the issue)
Changing the snapshot status with unlock_entity will likely work only if
the chain is fine on the storage

Re: Deploy Hosted Engine fails at "Set VLAN ID at datacenter level"
by Charles Lam
Hello,
I am having this same issue and have inserted the three new lines into /lib/python2.7/site-packages/ansible/modules/cloud/ovirt/ovirt_network.py yet it still occurs. I have rebooted the oVirt Node host. Do I need to insert the fix elsewhere or take other action to properly apply this fix?
Thank you very much,

oVirt API - New vm on specified storage
by Tommaso - Shellrent
Hi to all.
we are tring to create a new VM via API, but we are unable to
select the desidered storage where to deploy it.
We make a call like this:
CALL:
POST /ovirt-engine/api/vms?clone=true
Data:
{"cpu":{"topology":{"sockets":1,"cores":4,"threads":1}},"memory":4294967296,"memory_policy":{"guaranteed":4294967296,"max":4294967296},"disk_attachments":[{"disk":{"id":"925c999e-536f-4905-bc54-5cf64477a3a7","format":"cow","storage_domains":[{"id":"a772c71a-bd7b-4898-9497-120dcd853d96"}]}}],"name":"apitest.domain.com","fqdn":"apitest.domain.com","cluster":{"id":"890681f6-e0fe-11e9-81b5-0200007c8e05"},"template":{"id":"45da14a2-7f6f-43d9-9481-19a2034700fe"}}
But the reply is:
Reply HTTP 400
{
"detail" : "For correct usage, see:

}
Have someone some suggestion or good example??

memory overcommit in oVirt
by yam yam
Hello,
I thought memory overcommit feature in oVirt utilizes host's overcommit features by manipulating kernel variables like vm.overcommit_ratio, vm_overcommit_memory.
but, I've just confirmed that those variables didn't change at all.
I wonder if oVirt's overcommit really has nothing to do with that of host
and if so, how does oVirt manage memory overcommit.
