It looks like an old howto, we will need to update or remove it.

For the interfaces to be owned by oVirt, you will need to add the host to
Engine.
So I would just configure everything up to the VLAN (slaves, bond, VLAN)
with NetworkManager prior to adding it to Engine. The bridge should be
created when you add the host.
(assuming the VLAN you mentioned is your management interface and its ip is
the one used by Engine)

No (for 4.1 and 4.2)

Do I need to manage the networking using (nmtui) NetworkManager?

You better use cockpit or nmcli to configure the node before you add it to
Engine.

Re: [ovirt-users] Windows 10 floppy not found during setup

[Christophe TREFOIS]

VMs use a vNIC on ovirtmgmt logical network. There should be nothing to do with 
the engine itself.

It was working fine for us after we are able to load the drivers properly.

Re: [ovirt-users] Windows 10 floppy not found during setup

[Vincent Royer]

Thanks I tried it and it did in fact work.  Just threw me off because all
the instructions say to load the floppy.

My windows install got right up to the point where it was loading the NICs,
and then it all came crashing down.  I expected the VMs and the engine to
be able to share the same NIC, but I suppose it doesn't work that way.

We had to do the swapping CD trick for Windows 10 yes.

Re: [ovirt-users] Ovirt backups lead to unresponsive VM

Hi All,

I have reproduced the backups failure. The VM that failed is named
Win-FileServer and is a Windows 2016 server 64bit with 300GB of disk.
During the cloning step the VM went unresponsive and I had to stop/start
it.
I am attaching the logs.I have another VM with same OS (named DC-Server
within the logs) but with smaller disk (60GB) which does not give any error
when it is cloned.
I see a line:

EVENT_ID: VDS_BROKER_COMMAND_FAILURE(10,802), Correlation ID: null, Call
Stack: null, Custom ID: null, Custom Event ID: -1, Message: VDSM
v2.sitedomain command SnapshotVDS failed: Message timeout which can be
caused by communication issues


I suggest adding relevant vdsm.log as well.
Y.


I appreciate any advise why I am facing such issue with the backups.

thanx,

[ovirt-users] Change emulatedMachine in vm.conf. Hosted Engine not boot properly.

[reznikov_aa]

Greetings, friends!
I have problems start HostedEngine after upgrading Ovirt from version 
3.6 to 4.0.
VM starts, but boot is not continue properly. If I are connected via 
vnc, i can see smbios…, machine id…, and nothing more.
I was able to start HE vm by changing the type of emulatedMachine from 
‘pc’ to ‘rhel6.5.0’ in file vm.conf, and start with --vm-conf=myvm.conf… 
How can I change the vm.conf in OVF store? The solution described here 
https://access.redhat.com/solutions/2209751, not help me, or maybe there 
are any other solutions to this problem?


My test ovirt lab is vmware workstation.
vdsm-4.18.21-1.el7.centos.x86_64
libvirt-libs-3.2.0-14.el7_4.7.x86_64
ovirt-engine-4.0.6.3-1.el7.centos.noarch

Thanx.Alex.

[ovirt-users] Windows 10 floppy not found during setup

[Vincent Royer]

I am trying to install Windows 10 on Ovirt 4.2

I pushed the virtio-win iso and vfd files to my ISO domain.   I created the
VM and loaded the CD rom with the windows install ISO and in the "run once"
settings I chose the virtio-win selection as a floppy.  However when
entering windows setup, there is no drive to install to, and no floppy
shows up in the usual place to install the drivers.

the installation did succeed when selecting "IDE" as the target disk
instead of the virtio or virtio-SCSI options.

Is there any way to install the drivers after the fact and then change the
disk mode from IDE to virtio?

Is the method on this page
https://www.ovirt.org/documentation/how-to/virtual-machines/create-a-windows-7-virtual-machine/

still relevant?  Looks like they suggest swapping the CD disk once the
windows setup has begun.

Thanks!
