Hi there,

So I went to VMWare training this week and one of the processes for P2V conversion involves booting to a Linux live CD on the physical server and executing:

cat /dev/[Pdisk1] > //[NFS server]:/[share]/[temp]

and then booting to the Linux CD on the VM and executing:

cat //[NFS server]:/[share]/[temp] > /dev/[Vdisk1]

I never knew you could use cat and redirection to clone a device, so my question is what's the difference between cat > and dd?

Thanks
