File System of choice for Linux Guests


I was wondering which file system would be the best choice for Linux guests? I presume a Linux guest on Windows host and Linux guest on Linux host probably have different 'best options'. So should be focus just be speed (?) since there's already some overhead with virtual to physical disk access and structure.

Should be linux OS independent but: I'm running a Slackware guest on a Vista host, so physical partition is NTFS.

Dunno what your reasons are to run Linux as guest and Vista as host but I think it is a bad idea and the other way around is much more productive.

Speed you loose by the file system is negligible as compared to running Slack in a VM, so choose your file system based on the normal considerations. That would be ext3/4.

Gaming, that's my only reason. I keep the slack vm running all other times.

I use btrfs for my Linux guests on Win7 host. Don't know if Pat keeps the kernels current enough though - haven't looked at Slack in a while.
ext4 would be my other option.

  • Linux guest file system choices are no different than on a physical machine: ext3 is safe, ext4 is probably better on recent kernels.
  • The virtual machine doesn't know its not running on actual hardware, its file system doesn't know its actually 'inside' an NTFS 'container' in your case.
I'm answering this post running slackware-current with ext4 file system inside VirtualBox v4.0.4, hosted on real hardware running slackware-13.1 on an ext3 file system.
