Why is the domU crashing; does it look at all related to these problems, or is it something different? Does the filesystem image check out ok with xfs_repair when this happens? If not, what does it find? Which files are truncated, system files or files that were being written at the time of the crash? And just to be clear, what exactly do you mean by truncated; that the data is correct up to EOF, but the file is smaller than you expect? Is this more than simply buffered writes getting lost, which is to be expected? -Eric > Our setup: > > Dom0 and > domUs are Ubuntu 8.04 64 bit Server edition. The domUs use tap file > based backends.
