oVIRT / GlusterFS / Data (HA)
by Devin Acosta
I have created an oVIRT 4.0.6 Cluster, it has 2 Compute nodes, and 3
Dedicated Gluster nodes. The Gluster nodes are configured correctly and
they have the replica set to 3. I'm trying to figure out when I go to
attach the Data (Master) domain to the oVIRT manager what is the best
method to do so in the configuration? I initially set the mount point to
be like: gluster01-int:/data, then set in the mount options
"backup-volfile-servers=gluster02-int:/data,gluster03-int:/data", so I
understand that will choose another host if the 1st one is down but if i
was to reboot the 1st Gluster node would that provide HA for my Data
domain?
I also configured ctdb with a floating-ip address that floats between all 3
Gluster nodes, and I am wondering if I should be pointing the mount to that
VIP? What is the best solution with dealing with Gluster and keeping your
mount HA?

oVirt installs 3.6 repos for 4.0 compat cluster
by James
Hi guys,
I'm trying to servers to a new oVirt 4.0 cluster. I've upgraded the
engine (not hosted, standalone) to version 4.0.6.3 and run engine-setup
and everything seemed to go fine.
When reinstalling oVirt on a host after removing it from the 3.6 compat
cluster into a 4.0 compat cluster causes issues when reinstalling and
setting up the management network for some reason. I haven't been able
to track this issue down fully yet.
Whats weird is that even when a fresh new host is installed and added to
the grid for some reason oVirt installs the repos for oVirt 3.6 on the
host. I'm sure this is done by oVirt itself since they aren't there
before I install the host and we don't manage these outside of that. It
also just stalls at "Activating" the host and I can't do anything with
them after that.
Shouldn't it be installing version 4.0 for this cluster? I've triple
checked its set to version 4.0 compatibility and the data center its in
is also set to this level.
Unsure what logs I can provide but any help would be greatly
appreciated!
Cheers,
James

[PySDK v3] Choose storage domain
by Nicolas Ecarnot
Hello,
When trying to create a VM by cloning a template, I found out I couldn't
choose the target storage domain :
[...]
vm_storage_domain = api.storagedomains.get(name=storage_domain)
vm_params = params.VM(name=vm_name,
memory=vm_memory,
cluster=vm_cluster,
template=vm_template,
os=vm_os,
storage_domain=vm_storage_domain,
)
try:
api.vms.add(vm=vm_params)
[...]
I'm getting :
Failed to create VM from Template:
status: 400
reason: Bad Request
detail: Cannot add VM. The selected Storage Domain does not contain the
VM Template.
... which I know, but I thought that, as with the GUI, I could specify
the target storage domain.
I made my homework, and I found a nice answer from Juan :
http://lists.ovirt.org/pipermail/users/2016-January/037321.html
but this relates to snapshots, and not to template usage, so I'm still
stuck.
May I ask an advice?

packages that can be updated without maintening hosts
by Nathanaël Blanchet
Hi
The update notifier in the webadmin was originally designed to alert for
new vdsm* packages. Now, I noticed that available update of virt
packages and more are notified. I know that hot updating qemu-kvm
package does break vms that are running on concerned hosts, but what
about other one like libvirt-client? I know it is recommended to put in
maintenance while updating, but can we update some minor packages
without waiting for migration?
