I'm trying to install laravel on my computer with homestead environment. I followed all steps on the official documentation. And when I execute my "vagrant up" my console displays the following error.
.
Stops at SSH auth method. Previously I configured the ssh-keygen with "ssh-keygen -t rsa -b 4096 -C "me@email.com"
I added the host piece at .rb file: 
Even .yaml file. I think I edited properly 
At hosts file I added: "192.168.10.10 administracio.dev" at the bottom of the file.
And then when I let this error crash it shows the following error:
Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.
If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.
If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.
If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.
SOLUTION: I activated the Hardware acceleration in the BIOS environment.
