During an upgrade my kernel got corrupted and the server went down. Thankfully OVH offers a Netboot and Network mode. I used the network option and chose one of the available kernels, which dropped me in one of my own installation and executed the following:
To reinstall the current linux kernel:
List available kernels
apt-cache search linux-image
Reinstall the kernel:
apt-get install --reintall linux-image-3.16.0-4-amd64
Update grub configuration:
update-grub
And hard reboot server
