Check if the cpu virtualization support is enabled on BIOS.

You can also check if the cpu supports the virtualization linux command - egrep -c '(vmx|svm)' /proc/cpuinfo

If the output is 0 , that means the virtualization is not supported , 1 or greater than 1 means its good to go.

2019-09-19 02:40:49 -0500 answered a question Persistent volume in TOSCA Template

Hi Nehal,

You can use a cinder volume attached to the vnf vm and preserve the cinder volume on termination of vnf (Ensure the r/w activity carried by vnf to cinder is stopped before termination to ensure no cinder volume corruption ), As per the tacker project this is already a blueprint/spec for this as well, you can check it -

2019-05-20 05:32:10 -0500 answered a question Virtualbox on OpenStack Image

Vritualization is not enabled on the instance spawned up on openstack. you can check it via command

cat /proc/cpuinfo | grep vmx

You need to enable nested virtualization. Linux KVM supports nesting on recent virtualization-enabled processors. On compute node set

echo "options kvm-intel nested=y" >> /etc/modprobe.d/dist.conf

Update nova.conf with -:


This is valid only for kvm hypervisor.

Reboot your compute node and Validate that nested virtualization is enabled
