We’d like to configure cache to none for image in qcow2 format. It was working fine before 5.4.
Versions of the related components and OS (frontend, hypervisors, VMs):
OpenNebula 5.4 on CentOS 7 using KVM
Steps to reproduce:
I’m configuring this in /etc/one/vmm_exec/vmm_exec_kvm.conf
DISK = [ driver = “qcow2” , cache = “none”]
then I restart opennebula services and deploy a VM using a qcow2 image
virsh dumpxml VM shows no cache settings.
virsh dumpxml VM should show cache settings according to /etc/one/vmm_exec/vmm_exec_kvm.conf. Here it should be cache=none in the libvirt VM XML definition.
