At least with 2.6.36.4-DomU barriers seems to be enabled: blkfront: xvda1: barriers enabled (tag) blkfront: xvda2: barriers enabled (tag) blkfront: xvda5: barriers enabled (tag) blkfront: xvda6: barriers enabled (tag) blkfront: xvda7: barriers enabled (tag) blkfront: xvda8: barriers enabled (tag) xvda1 is ext3 (root fs) with the mount option barrier=3D1, but this doesn= =E2=80=99t=20 seem to work (EXT3-fs: barriers not enabled). The other filesystems are=20 ext4 without explicit barrier options and don=E2=80=99t have log output=20 concerning barriers. For now I can=E2=80=99t make tests since I=E2=80=99m not at home for the ne= xt days. Then=20 I will try to get logs as well. Since the filesystems are changed to read= =20 only, the logs are not written to disk, so I have to use other methods. >I don't try to put disks as partitions. Let me try that.

For now I can=E2=80=99t try it. Besides /boot in Dom0 all my partitions are= LUKS=20 encrypted. >> The DomU kernel is a 2.6.36.4 vanilla kernel.
