[ovirt-users] Re: Networking - How to pass all vlan (trunk) to a guest VM?

2018-11-04 Thread Jonathan Greg
Hi,

To give a try, I added a new vlan in my infrastructure but I didn't defined it 
in oVirt. I configured a sub-interface ens3.444 on my guest VM and the VM is 
able to talk to the external world.

However, as soon as I define I create a logical network (vlan444) in oVirt and 
attach it to the host. the VM communication stop. It looks like that we cannot 
trunk a vlan to a guest if this vlan is defined in oVirt.

Is it the expected behavior?
Is there a workaround?
Will this feature be available in the next release(s)?


Thanks

[ovirt-users] GlusterFS distributed replicated with arbiter on 4 nodes - settings

2018-11-04 Thread Jarosław Prokopowski
Hi Guys,

I would like to use GlusterFS distributed-replicated with arbiter volume on
4 nodes for oVirt.
Can you tell me what tuning parameters should I set for such volume for
best VM performance?

Does it make any sense to upgrade from Glusterfs 3.12 to 4.1 or even 5.0?

Thanks!
Jarek

[ovirt-users] Re: Desktops as Nodes and Client?

2018-11-04 Thread Drew Gilbert
Thanks for the suggestions, I'll look into them.  I am looking for a user
management solution, but we also use mostly windows desktops and Office365,
so will probably end up with some solution based on Azure AD.

For context, one other reason for wanting the desktops to be nodes is that
the base OS could be oVirt node. Our DR site provider charges a lot if we
need to update the OS image of desktops, so using VMs could be a way to
allow us to keep things up to date without incurring the costs.

Thanks again,
Drew

Please note that having to reach the gluster arbiter over a geographical
