Hi Yedidyah, sorry for the delayed answer.

I had a look at it, but nothing relevant shows up besides this line:

I didn't. I just enabled nested virtualization in the host and tried to deploy.

In the Cluster I have the Intel Broadwell Family, and as the VM CPU I have the default cluster CPU which is the one I just referenced. Not sure if anything else should be done.

I just saw this in the log:
2019-05-24 12:44:56,000+0100 DEBUG otopi.ovirt_host_deploy.hardware
hardware._isVirtualizationEnabled:208 virtualization support GenuineIntel (cpu: False, bios: True)
So the CPU is not able to support virtualization. Why could be that?
Hi, can you please share the output of cat /proc/cpuinfo ?
Hi Simone,
Please find attached the output (assuming you meant the VM that is meant to be added as a host). You'll probably see the model name as Haswell because I forced it to test, but the same happens with Broadwell.
OK, vmx flag is not there so this VM doesn't support virtualization and for that you have to enable nested virt support on the underlying level. What (SW) are you using on the underlying layer?
Let's try to recap: L0 is your physical machine L1 is the VM you are going to use as a virtualization host for oVirt L2 are the VM you are going to create with oVirt
In order to be able to start a L2 VM from oVirt, you have to enable nested virtualization support on your L0 physical host.
Ok, the output I sent in the previous e-mail was for L1. For L0 I'm sending the cpuinfo log now.
I saw in the code, the flag that is returning false at deployment of L1 is this:
cpu_ok = self._cpu_has_vmx_support()
Which calls the _cpu_has_vmx_support():
def _cpu_has_vmx_support(self): eax, ebx, ecx, edx = self._cpuid(1) # CPUID.1:ECX.VMX[bit 5] -> VT ret = ecx & (1 << 5) != 0 self.logger.debug('vmx support: %s', ret) return ret
From that, am I assuming well that vmx support should be enabled also for L1? If so, what could be the reason for not being enabled?
Nested virtualization support on L0 is supposed to enable virtualization support (vmx flag) on L1. How you defined and started your L1 VMs?
Thanks again.
Thanks.
