Migrate non local Physical running Linux Servers, CentOS, to VHD to run in VM on Hyper-V

I am looking for the best method to migrate non local physical running Linux servers to run on Hyper-V.

The servers are running CentOS. They will need to be converted to VHD.

Is this possible? What's the best method if it is? Are there tools available to perform the migration, or to help?

I know there are some tools for migrating Windows Servers like Disk2VHD and SCVMM, but am not aware of anything for Linux that is not already in a VM and is not local.

Thanks,

Craig
