IP address doesn't appear in the host network interfaces tab
by Nathanaël Blanchet
Hi all,
I try to change my migration network from one to an other. To do such a
thing I assigned an IP on the new vlan fo r each of my hosts by
dhcp.but when changing the migration network at the cluster level,
engine complains that my host doesn't have IP.
I tried the "Sync all networks tab" to refresh, but nothing happens.
Howver IP in the vlan do exist on the host.
The only workaround to do this is to restart vdsmd and then, IP appear
and I can go further.
Can it be considered as a bug?

used bandwidth when live migrating
by Nathanaël Blanchet
Hi all,
We use in production a dedicated 10G vlan link for live migration. In
the cluster option tab I put the migration bandwidth limit to 10000
Mbps. Everything work as expected and now 25 vms on a host migrate in a
few seconds (excatly 13), but I'm not able to measure the real consumed
bandwidth. I want to evaluate such a thing beacuse my goal is to
dedicate a vlan for gluster ont the same 10G nic, and I don't want an
overload issue with gluster when vms migrations happen.
So my questions are : how does live migration work? Is it a RAM to RAM
transport between two hosts? Are migration bandwidth limited by I/O disk
anywhere or by the nic capabilities? Could 10Gbps be fully used for such
staff? What would you advice to make work gluster and migration on the
same nic (QoS?)
Thank you for help.

4.0.5 create vm from template on cinder/ceph backed storage
by Jordan Conway
I've got a problem where since upgrading to 4.0.5 I am still unable to
create a vm from a template.
The issue now is that it seems to be stuck in a loop trying to and failing
to create the vm, which is making my logs explode with the following
https://paste.fedoraproject.org/489161/14799981/
And in the engine UI "Failed to complete VM fromtemplate-1 creation."
thousands of times.
The issue started I believe with this sql error
https://paste.fedoraproject.org/489183/00010131/
Any insight on how I can stop the persistent error would be appreciated, as
it is also preventng me from running engine-setup due to running jobs, even
though vdsclient shows nothing.
vdsClient -s 0 getAllTasksStatuses
{'status': {'message': 'OK', 'code': 0}, 'allTasksStatus': {}}
Thank you,
Jordan Conway

vm.conf on one of the node is missing
by knarra
Hi,
I have three nodes with glusterfs as storage domain. For some
reason i see that vm.conf from /var/run/ovirt-hosted-engine-ha is
missing and due to this on one of my host i see that Hosted Engine HA :
Not Active. Once i copy the file from some other node and restart
ovirt-ha-broker and ovirt-ha-agent services everything works fine. But
then this happens again. Can some please help me identify why this
happens. Below is the log i see in ovirt-ha-agent.logs.

ovirt 4.0.6 - live disk migration fails

If I try to migrate a disk of a running VM to another storage domain it
fails with the following message:

Migrating disks of stopped VM's continues to work.

Storage questions
by Oscar Segarra
Hi,
I'm planning to deploy a scalable VDI infraestructure where each phisical
host can run over 100 VDIs and I'd like to deploy 10 physical hosts (1000
VDIs).
In order to avoid performance problems (replicating 1000VDIs changes over
gluster network I think can provoque performance problems) I have thought
to use local storage for VDI assuming that VDIs cannot be migrated between
phisical hosts.
¿Is my worry founded in terms of performance?
¿Is it possible to utilize local SSD storage for VDIs?
I'd like to configure a gluster volume for backup on rotational disks
(tiered+replica 2+ stripe=2) just to provide HA if a physical host fails.
¿Is it possible to use rsync for backing up VDIs?
If not ¿How can I sync/backup the VDIs running on local storage on the
gluster shared storage?
If a physical host fails ¿How can I start the latest backup of the VDI on
the shared gluster?
Thanks a lot
