On engine VM I see a reference to " CreateStorageDomainVDS failed: Invalid

BTW: in my second test with the workaround of pre-creation of directory I
scratched all before and set the gluster network to 192.168.123.0 to avoid
conflict with the temporary bridge. I didn't get anymore the json error
described in item 3) of my first post

Searching around I found these two bugzillas for 4.2 regarding
ovirt-imageio-daemon related to missing dir/files in /var/run/vdsm because
of errors in
systemd-tmpfiles-setup.service startup (unknown vdsm user and kvm group)

https://bugzilla.redhat.com/show_bug.cgi?id=1576479
https://bugzilla.redhat.com/show_bug.cgi?id=1639667

So the temporary workaround was to pre-create them before running the setup

 mkdir /var/run/vdsm
 chmod 755 /var/run/vdsm
 chown vdsm.kvm /var/run/vdsm
 mkdir /var/run/vdsm/dhclientmon
 chmod 755 /var/run/vdsm/dhclientmon/
 chown vdsm.kvm /var/run/vdsm/dhclientmon/
 mkdir /var/run/vdsm/trackedInterfaces
chmod 755 /var/run/vdsm/trackedInterfaces/
chown vdsm.kvm /var/run/vdsm/trackedInterfaces/
mkdir /var/run/vdsm/v2v
chmod 700 /var/run/vdsm/v2v
chown vdsm.kvm /var/run/vdsm/v2v/
mkdir /var/run/vdsm/vhostuser
chmod 755 /var/run/vdsm/vhostuser/
chown vdsm.kvm /var/run/vdsm/vhostuser/
mkdir /var/run/vdsm/payload
chmod 755 /var/run/vdsm/payload/
chown vdsm.kvm /var/run/vdsm/payload/

Then a "systemctl start ovirt-imageio-daemon" completes ok.

Host addition completed ok.
The problem now is at final step where I get

[ovirt-users] Re: Ovirt VDI Solution network issue

[mdcarr]

Please ignore my last as I was able to attach the virt-iso and get the drivers 
loaded on the Windows VM. Now the network says Unidentified network ip 
169.x.x.x.

So back to asking our network admins to assign a ip based on mac address 
correct?  Thanks!

[ovirt-users] Re: Ovirt VDI Solution network issue

[mdcarr]

Thanks for the reply. That makes sense with the dhcp server and I think I found 
why its not getting an ip automatically via dhcp.  When I use spice to login to 
windows 7 and go to device manager it does not have a driver loaded for the nic 
card.  The server is a dl380 G7 running centos 7.  

I've done vdi on Ovirt in the past and don't remember having to install network 
drivers for Windows boxes but maybe I missed a step? Would I download the 
drivers from HP and burn to a cd to get them loaded onto the VDI?  I only see 
server nic drivers from HP but maybe their is a universal one or I could search 
the manufacturers website? Appreciate the help.

ovirt stopped accepting new deployments or uploading ISOs, they just stay as 
locked disks.  I checked ovirt-engine log and see constant errors like below:

I checked the ovn provider in the admin portal and it's set correctly to

[ovirt-users] ovirt node ng 4.3.0 rc1 and HCI single host problems

[Gianluca Cecchi]

Let's start a new thread more focused on the subject

I'm just testing deployment of HCI single host using oVirt Node NG CentOS 7
iso

I was able to complete the gluster setup via cockpit with these
modifications:

1) I wanted to check via ssh and found that files *key under /etc/ssh/ had
too weak config so that ssh daemon didn't started after installation of
node from iso
changing to 600 and restarting the service was ok

2) I used a single disk configured as jbod, so I choose that option instead
of the default proposed RAID6

But the playook failed with

[ovirt-users] Hypervisor host CPU utilization metrics

[Sigbjorn Lie-Soland]

Hi,

Linux see twice the amount of CPUs for a host with SMT/hyperthreading enabled. 
Inspecting the individual cores presented to the operating system using mpstat 
shows that the guests are running primarily on the “physical cores”, which is 
expected as the system is SMT aware. The “hyperthreaded cores” are showing 
guest activity when the host cpu is heavily loaded. Using the traditional tools 
such as top and vmstat does not take hyperthreading into consideration when 
calculating the total cpu% usage, again, as expected.

How is the hypervisor host CPU utilization metrics in Ovirt calculated when a 
hypervisor host has SMT/hyperthreading enabled? Does Ovirt calculate in the 
same manner as the traditional vmstat/top/etc Linux tools, or does it only 
count CPU usage on the “physical cores” on the hypervisor? Does it read CPU 
metrics from the Intel PCM (https://github.com/opcm/pcm 
) ?

Does the “Count Threads as Cores” setting affect how the host hypervisor CPU 
utilization metrics are calculated?

The reason for asking is when using tools for capacity and utilization 
reporting to attempt to establish cluster growth and to anticipate when and how 
much hypervisor capacity to add, we need the input utilization data to be a 
correct representation of what is happening at the hypervisor host.

Thanks.

Siggi

[ovirt-users] exporting VMs using vdsm-client

[Callum Smith]

Is it possible to export VMs using vdsm-client to import into a new oVirt 
engine in a case of catastrophic failure such that they can be imported into a 
new setup?

Regards,
Callum

Hi Sandro, thanks for this release!

I'm just testing deployment of HCI single host using oVirt Node NG CentOS 7
iso

I was able to complete the gluster setup via cockpit with these
modifications:

1) I wanted to check via ssh and found that files *key under /etc/ssh/ had
too weak config so that ssh daemon didn't started after installation of
node from iso
changing to 600 and restarting the service was ok

2) I used a single disk configured as jbod, so I choose that option instead
of the default proposed RAID6

But the playook failed with

The page says K1 and K2 do not support vGPU so you could only do Host

That’s only for vgpu which it doesn’t support, so you do not see any mdev

Hello Everyone,
I am not sure what would it be the pieces needed to have an external repo
that I can manage and use at the client site for downloading customized
templates.
ie: how an external docker repo works
Any ideeas on this ?
Thank you !
Have a nice day,

[ovirt-users] VDO volume - storage domain size

[Leo David]

Hello Everyone,
I'm I trying to benefit of vdo capabilities,  but it seems that I don;t
have too much luck with this.
I have both created a vdo based gluster volume usign both following methods:
- at hyperconverged wizard cluster setup by enabling compression per device
- after installation, by creating a new gluster volume and enabling
compression

In both cases,  I end up with a real device size gluster volume/storage
domain, although the vdo's appear in node's cockpit UI as being 10 times
then physical device.

ie: 3 nodes,  each having 1 x 900GB ssd device, turns into 9t device vdo
device per host, but the storage domain (gluster  replica 3 ) ends up as
being 900GB   .
Am I missing something ,  or maybe doing something wrong?
Thank you very much !

Leo

Yes, if your network team would assign an IP for that MAC, e.g. for
static assignment inside the virtual machine or via DHCP.
Please note that oVirt allows you to manage the MAC addresses of the
VMs.
(With the exception of external networks like OVN or OpenStack
Neutron networks) oVirt's VM networking is focused on layer 2, and does
not care about layer 3 issues like IP address management and routing.

>> I will be creating around 20 vm's that

I could image that there are some less straight forward solutions like
cloudinit, or a script inside the VM possible, but I would prefer to
manage the IP addresses outside the guests, e.g. by a DHCP server.

> Am I
>> missing something or is there a better way to setup the LAN for this host?

Straight forward would be the use a DHCP server for IP address
management.
A simple way would be to use a DHCP server of your host management
network. The host management network is represented by the logical
network "ovirtmgmt" in oVirt. This DHCP server is probably managed
by your network team.

A more complex way would be to create a dedicated VLAN on layer 2,
represented in oVirt by a new logical network with a VLAN tag.
All the VDI VMs could be attached to this new logical network and a
dedicated node could provide higher layer services like a DHCP server
and IP routing between the new VLAN and the host management network.
This node could be a usual physical router, or a oVirt VM, with access
to both layer 2 networks.
Please note that the already existing routers have to learn about the
new network, if the VDI clients cannot added to the new VLAN.
