I believe VMware uses real mode transiently, which is not possible when 
vmx extensions are enabled.  So using VMware and kvm concurrently is not 
possible.

Maybe one of the following will suit:
- run the Windows 98 image in qemu (without kvm).  This will have lower 
performance, but may be adequate.
- run VMware within a kvm VM, and run Windows 98 within that.
- unload the modules.  This isn't a lot of fun and prevents concurrent 
operation.
