[ovirt-users] Installing oVirt node 4.1 in nested virtualization on KVM / ESXi.

[Open tech]

Looked into CPU settings for KVM. Looks like nested virtualization is not
the default behavior in KVM.

Check for Nested Virtualization:

sudo virt-host-validate


[root at ovirt1 ~]# sudo virt-host-validate

  QEMU: Checking for hardware virtualization
  : FAIL (Only emulated CPUs are available, performance will be
significantly limited)

  QEMU: Checking if device /dev/vhost-net exists
  : PASS

  QEMU: Checking if device /dev/net/tun exists
  : PASS


Follow the following to enable nested virt :

https://www.server-world.info/en/note?os=CentOS_7&p=kvm&f=7


Shut down the node VMs. Check the "*Copy host CPU configuration* checkbox".



I was able to proceed to hosted engine installation.


Regards,

HK
