Any idea?

/lib/modules is indeed mounted read-only. Same as the kernel, it is provided by dom0, so VM have no influence on the kernel. So, in short it is senseless to install kernel modules in the VM (using distro package). What exactly linux-headers package try to write there? And why do you want to install it?

That'd require having packaged headers exactly for kernel VM is using. Currently we have them only as rpm package... So I think in practice the only way to go is to get that rpm package (kernel-devel) and somehow install it in Debian VM (either using "alien" or manually extracting to some directory and pointing build scripts to use that).

This would be much easier when #1354 got implemented. I wonder why we hadn't ticket for this already - the idea isn't anything new.

We'll go PV Grub way (#1354).
