How to set up vagrant 1.7 + virtualbox 5?

Question

virtual box

Hello!
I managed to upgrade to boot 15.10, after that vagrant 1.6 refused to work on virtualbox 5. After a few hours, I found out that it was not possible to correctly assemble vagrant 1.6 + virtualbox 4.3 on boot 15.10 (linux-headers-3.26 is not supported, as I understand it - and he needed).
I assembled vagrant.17 + virtualbox 5, I do vagrant up and everything stops at this moment:

==> default: Running 'pre-boot' VM customizations...
==> default: Booting VM...
==> default: Waiting for machine to boot. This may take a few minutes...
    default: SSH address: 127.0.0.1:2222
    default: SSH username: vagrant
    default: SSH auth method: private key
    default: Warning: Connection timeout. Retrying...
    default: Warning: Authentication failure. Retrying...

I can go to the virtual machine (vagrant ssh), but there is an empty centos.
The rollout of the virtual machine goes through the folder, installing all the packages on the virtual machine is not an option.
my solution is to demolish the axle and put 14, I don't like it. Maybe there are some suggestions?

изучив интернет, выяснил что не прокидывается ssh-key и не можем залогиниться...
