Reported by: Cova Owned by:
Priority: major Component: other
Version: VirtualBox 4.2.12 Keywords: btrfs
Cc: Guest type: Windows
Host type: Linux

Description

On a linux machine with btrfs filesystem, installation of a guest goes just fine but at first restart the guest freezes with popup showing "20%" during launch phase. Installing the same machine on XFS, no problems at all. I've seen similar reports, but with slightly different behaviours and declared fixed. host machine: linux 3.9.5 x86_64 (gentoo) guests: W8/W7 64bit attached: vbox.log of failed session

Was this a one-time occurrence or is it reproducible?

Replying to michael:

Was this a one-time occurrence or is it reproducible?

Happens every time, always reproducible.

I can add that I tested both packages available on gentoo (one built from sources, the other using binary from virtualbox site) and the behaviour is the same.

I'm experiencing the same issue running Fedora 19 and btrfs. However, if I enable "Use host I/O cache" on the VM's SATA controller, the problem goes away.

In that case I assume that there is some problem when opening files with O_DIRECT on btrfs. We saw such problems with EXT4 and XFS before with older Linux kernels.

After some day, I'm no longer able to reproduce the issue. I don't know if this is relevant, as I've got no time to check kernels changelog, but I changed kernel and now I'm running on 3.10 and I'm not able to reproduce the same behaviour.
