If you are talking about an ELF core dump of the user-space qemu-kvm process
running on the host, then it's certainly not supported.  

As to whether it's possible, I suppose it could be done if a phyical-memory-read
function could be created for it, similar to what I asked about for live 
analysis
of a guest kernel run on/from the KVM host.
