Re: [ovirt-users] Nested KVM - vdsm-hook-nestedvt

2016-01-07 Thread Winfried de Heiden 

  
  
Hi all,
  
  Took me some time to find out. The kvm_amd modules was loaded
  correctly, but I had to change one more thing on the virtual
  machine:
  
  Edit Virtual Machine --> Host --> select "Pass-Through Host
  CPU". Afterwards (nested) kvm was available on the virtual
  machine.

First, make sure that you're enabling the nested feature for amd (just
noticed that the example used intel). Please show us the output of

# cat /sys/module/kvm_intel/parameters/nested

  
  
and sorry, did the same mistake again - use

# cat /sys/module/kvm_amd/parameters/nested


  
on the host (physical machine), lscpu inside the VM and VM XML - use

# virsh -r list
# virsh -r dumpxml {machine_id found in the list}

Thanks,

Not really true - fake_kvm_support enables QEMU emulation instead of
hardware virtualization (e.g. VT-x) instructions. It is also quite
broken in it's current state and fix is pending in cpuinfo branch at
gerrit.

I don't really understand the reason why fake_kvm would be used in
this case as AMD-v is enabled according to svm flag present -
following instructions should be correct for getting the flag passed
to the VMs.



  Please check to understand if nested support is enabled on your host:

if not

[ovirt-users] Nested KVM - vdsm-hook-nestedvt

2016-01-01 Thread Winfried de Heiden 

Hi all and happy new year!

I'm running oVirt 3.6 on EL7.

In order to test nested-kvm I installed vdsm-hook-nestedvt on the 
hypervisor and put "fake_kvm_support = true" in /etc/vdsm/vdsm.conf.


However, afterwards the hypervisor host cannot connect to the ovirt 
Manager, on ovirt Manager the engine.log will tell:


2016-01-01 15:21:42,105 WARN 
[org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] 
(DefaultQuartzScheduler_Worker-76) [71d1638c] Correlation ID: 29daf92c, 
Call Stack: null, Custom Event ID: -1, Message: Host bigvirt moved to 
Non-Operational state as host does not meet the cluster's minimum CPU 
level. Missing CPU features : model_Opteron_G3


After removing the option all works well again, but I'ḿ lacking the 
nested kvm option :( Is nested kvm only supported on a limited cpu's??
