Which is the default python version ?
Most probably ansible is  looking for python 3.X while the default is 2.7.

Have you tried to specify ansible_python_interpreter ?

the engine vm:

The physical host cpu is detected as:

model name : Intel(R) Xeon(R) Platinum 8260L CPU @ 2.40GHz

and its cpu flags:

flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat

avx512_vnni md_clear spec_ctrl intel_stibp flush_l1d arch_capabilities

The physical host itself is a 4.3.9 single host HCI system and during
install (made with 4.3.8) has been setup as "Intel Skylake Server IBRS SSBD
MDS Family" type cluster
I confirm that both in physical 4.3.9 and in another nested 4.3.9 enf I set
up, the related HostedEngine VM is started with:

-machine pc-i440fx-rhel7.6.0,accel=kvm,usb=off,dump-guest-core=off -cpu
Skylake-Server,spec-ctrl=on,ssbd=on,md-clear=on,vmx=on

Gianluca



If so, please note Cascadelake is not listed in supported CPUs:
> https://ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_using_the_cockpit_web_interface/#CPU_Requirements_SHE_cockpit_deploy
>

OK, but strange that I was able to install 4.3.8 without problems
Is there a way in HCI setup to specify a "lower level" cluster type from
the beginning?

Hello,
I have this problem I posted for beta4 also with the RC1 installation:

https://lists.ovirt.org/archives/list/users@ovirt.org/message/CR6XYIEYHT4N75UWEXMTJR2AKB3DYL6X/

At final stage when engine VM has to start from hosted engine storage domain

libvirt.libvirtError: unsupported configuration: unknown CPU feature:

any hint on how to workaround and test on my nested environment?

[ovirt-users] Re: Creating an Isolated/External Network

2020-05-08 Thread Luca 'remix_tj' Lorenzetto 
Hello,

you mean you want to create a network where no other virtual machines
are communicating, except from the two ones you created?

You need to create a new logical network, not on external provider,
but internally, with a new VLAN ID (if sharing the same interface of
other networks). Then you need to associate this network to the
network interfaces of each host. Ensure also the vlan id you specified
is configured on the switches where your hosts are connected.

[ovirt-users] Creating an Isolated/External Network

2020-05-08 Thread dsullivan56 
Hi all,

Obligatory I'm not sure if this is the right place to post and obligatory I am 
very new here. I could really use some help. I'd like to build an 
isolated/external network so that I can build two VMs that need to interact 
with each other and each other alone while they are being built. I'd like to 
protect them from interacting with other VMs I have and I'd like to protect my 
other VMs from interacting with them.

I attempt to create this network by going to Network > Networks > New, and I 
make sure to click the "create on external provider" checkbox and select 
"Disabled" under the "Network Port Security" drop-down menu. When I click "ok" 
I get the error message:

 "Error while executing this action: User is not authorized to perform this 
action".

This isn't an issue, I just went to the super user and had him try the same 
thing, and he gets this error message: 

"Error while executing action AddNetworkOnProvider: Failed to communicate with 
the external provider, see logs for additional details". 

The oVirt log wasn't that helpful, as it just told me the time oVirt failed to 
create the network. Neither my super user nor I can figure out why this is 
happening. Would greatly appreciate any advice you can give me. Thanks!
