Latex Large Matrix

I want to create this matrix.

$H=\begin{bmatrix}
0 & 0 & 0 & 0 & \ldots & 0 & \ldots\ldots & 1 & 1 & 1 &\ldots & 1\\
0 & 0 & 0 & 0 & \ldots & 0 & \ldots\ldots & 1 & 1 & 1 &\ldots & \alpha_{q-1}\\
\vdots & \vdots & \vdots & \vdots & xxxxx & \vdots & xxxxxxx  & \vdots & \vdots & \vdots & xxxxxx & \vdots\\
0 & 1 & 1 & 1 & \ldots & 1 & \ldots\ldots & 0 & 0 & 0 &\ldots & \alpha_{q-1}\\
1 & 0 & 1 & \alpha_2 & \ldots & \alpha_{q-1} & \ldots\ldots & 0 & 1 & \alpha_2 &\ldots & \alpha_{q-1}
\end{bmatrix}$

I get this error

Underfull \hbox (badness 10000) in paragraph at lines 318--330

By default, the maximal number of columns in a matrix of amsmath is 10. But you can change that:

\setcounter{MaxMatrixCols}{12}
