• test with modprobe

  • modprobe -r kvm_intel

  • modprobe kvm_intel nested=1

  ++ options kvm_intel nested=1
  

  Make changes persistent

• Add user to kvm

  ++ hugetlbfs    /dev/hugepages  hugetlbfs   mode=01770.gid=999   0 0 (999 == grep kvm cat/etc/group)
  

• Continue to resize hugepage RAM usage

• VBoxManage convertdd /dir/storage.raw /dir/storage.vdi --format VDI
