How to login into HPCloud Instance and edit Security Group using Hybridfox

Hybridfox is great tools for connecting with our cloud server. When you configure HPCloud server, then you should have this for manage your security groups and allowing several ports to be open. Because default group in HPCloud only allowing SSH port only.

Solve Vagrant “The guest additions do not match the install version of VirtualBox”

After upgrading my Virtualbox, I try build my base box and got this errors :

[ff] The guest additions on this VM do not match the install version of
VirtualBox! This may cause things such as forwarded ports, shared
folders, and more to not work properly. If any of those things fail on
this machine, please update the guest additions and repackage the

Guest Additions Version: 4.1.6
VirtualBox Version: 4.1.8

Yeap, this is happen because I have Ubuntu Oneiric on base box with old Guest Additions Version. Then, let go to the solution. First, remember your Virtualbox Version and download VBoxGuestAdditions with related version. For instance :

wget -c

Then we will mount and install VboxGuestAddition by :

sudo umount /mnt
sudo mount VBoxGuestAdditions_4.1.8.iso -o loop /mnt
sudo sh /mnt/

Now try to “vagrant halt” and “vagrant up” again to see if this works! :)
