Nested Virtualization

I've installed OpenStack Ocata on 3 x VMware instances. But it got me wondering if the playbooks autodetect if the host is a virtual instance and would configure the necessary KVM on qemu settings.

Thanks,

Refer: https://docs.openstack.org/ocata/inst...

Determine whether your compute node supports hardware acceleration for virtual machines:

$ egrep -c '(vmx|svm)' /proc/cpuinfo

If this command returns a value of one or greater, your compute node supports hardware acceleration which typically requires no additional configuration.

If this command returns a value of zero, your compute node does not support hardware acceleration and you must configure libvirt to use QEMU instead of KVM.

Edit the [libvirt] section in the /etc/nova/nova-compute.conf file as follows:

[libvirt]

virt_type = qemu
