Hi list,

I am seeing all the problems described in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/824089 with XCP 1.5 beta (1.4.99)
I am using barrier=0 in my fstab mount options on all ubuntu 12.04 guests both hvm and pv and still seeing corrupted ext3 and ext4
partitions resulting in loss of data from the guest and even completely unbootable guests

Towards the end of the ubuntu bug report Malcolm Scott indicates that this bug is known by Citrix and needs to be fixed on the dom0

Will this patch be available for XCP as well as XenServer ?
When can we expect it ?
