    [SOLVED] Issues running VirtualBox on ext4 (home partition)


    Last week, I bought a new HDD that was on sale, and figured it would be best to use it on my PC, and use the old for backup.

    So, I started over from scratch, as I don't want to transfer any bad issues from one drive to the other. But this time, I done one thing different, formatting my Mint install as ext4, rather than ext3, what I normally use. The issue about ext4 came up in another thread, and it was suggested to run ext4 over ext3.

    Performance wise for the OS, no problems to report. But when opening a VirtualBox VM (Windows Vista) an hour ago, there are 2 warnings displayed, that the I/O in the guest had to be made permanent, and there is the potential for virtual drive degrading with the host being formatted as ext4. This on only my 2nd day with this setup, and already have 3 VM's created. I'll have 11VM's when it's said and done, and I'm leery of going any further.

    Anyone else having these warnings with VirtualBox (or any other VM software) installed on ext4?

    EDIT: I do have separate OS & Home partitions.

    You should enable the host cache when using ext4 and virtualbox. Otherwise, it should be safe.

    Virtualbox 4 on Ext4 error – host I/O cache will now be enabled

    What I done was left my (/) partition as is, and formatted my (home) partition as ext3, this solved the issue. No more warnings from VirtualBox as to this issue.
