kvm-15 on top of 2.6.20 - unresolved symbols

Finally I got some time and played with this some more. The unresolved symbols are caused by the fact that the kvm module fails to load:
FATAL: Error inserting kvm (/lib/modules/2.6.20/extra/kvm.ko): Device or resource busy
I narrowed it down the following:
r = register_filesystem(&kvm_fs_type);
if (r)
goto out3;On my system the above code fails with EBUSY. Any
ideas?
Thanks,
Emil

Avi,
I tried using kvm-15 on top of 2.6.20, but when I
try

to load kvm-intel I get unresolved symbols. The
modules from kvm-14 load fine in the same
configuration.

Perhaps you have one module from kvm-14 and another from kvm-15?
Please post to [email protected], not to me directly.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

kvm-15 has a bug where it succeeds in initializing the module but returns failure. So the filesystem is registered, module loading fails, and when you reload the module it can't register the filesystem again.
The fix was posted in
http://article.gmane.org/gmane.comp.emulators.kvm.devel/1537. I'll release kvm-16 shortly so others don't trip over it.
