[vbox-dev] [PATCH] [SVN] Please Merge 7 VirtualBox Kernel Modules into the Linux Kernel

[Alexey Eromenko]

Outside of hackers, no one really replaces their kernels.
1. Home users use whatever their distro have (Ubuntu, openSUSE, Fedora, ...)
2. Enterprise users stick to their Red Hat Enterprise Linux (or CentOS
or OEL) and use it's kernels only.

But the question is: How hard would it be to achieve a stable API/ABI
for host-side vboxdrv, like KVM does ? (KVM kernelspace can be matched
with any recent Qemu user-space, so it is compatible)

IMO Today vboxdrv does too much guest-host communication (such as Vbox
execute on the host), which changes from one version to the next. But
if it did only virtualization (VMX/SVM) it would be stable.

Is it worth the effort ? (I dunno, but if it won't add new community
developers, probably not.)
