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?

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?

Use cases:

• Non-Qubes-Whonix builds try to install it (ok, that can be worked around)
• kernel module development, I wanted to compile a kernel module.

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).
