Hi,

I have to create a VMhost from a server an I am doing this by using two Knoppix live CD'R's and conencting the VMhost machine to the server via switch. On in the original server and one in the VM HOST and I copy the drive over from the original server using the dd comand. When determing how big of a VMHOST I should create I did a df -h on the original drive and came up with 8.5GB total space so I created a VM of 11 GIG. When I booted the server with Knoppix I ran a sfdisk -l and it approximately the same number of GIGS. But when I ran the dd command on the original server it stalled after a while since it said it ran out of space at 11GIGS!

Can anyone tell me an effective way to determine how much Virtual Disk Space I need to create when cloning a server?

If you're copying the disk entire, consider the size of the entire disk and not just the size of the partitions.. If you're copying partitions, be sure you are just copying a partition(i.e. /dev/hda1) instead of the disk entire (i.e. /dev/hda). Can you describe the procedure in more detail? What software transfers the information from the old server to the new?
