Under Windows 7 with VMWare workstation 8, I want to run a Linux-VM with Ext3/4 as guest filesystem. I want the VM to have maximum read/write performance. So I'm thinking about the best hard drive setup for the VM. Should I give the VM access to a physical disk, so that the VM can access the disk natively using just Ext3/4?
The other option would be to create a virtual disk container. This would mean mapping the Ext3/4 filesystem inside the VM over the VMWare VMFS to a NTFS filesystem on the physical hard disk. This approach has some advantages in terms of backup and partitioning.
What is the impact of using VMFS mapping? Will it steal a lot of disk performance, or will I never notice the difference, so that I can also choose using a virtual-physical-mapped filesystem?
