One thing you/VMWare may want to look at is it turns out that "vmw_vmci", part of the kernel tree (CONFIG_VMWARE_VMCI) has to be compiled into the kernel as a module so udev can properly create the Misc device node (I'd tried making it a built-in and messing with udev rules and the other, compiled-in-later VMWare module loading system didn't seem to like that). Maybe some sort of mitigation for this can be done there, putting it back in-tree? But anyway, I'll send you a .tar.bz2 in a little bit. -Kenny -- Kenneth R.
