# Script to wrap a xentrace invocation to log it to a block-attached
# VDI in dom0, so it does not fill up dom0.
# The VDI has the other_config:xentrace flag set to 1, so these can be
# identified later on as xentrace records.
# The VDI contains a ext3 fs (no partition table) and single file "trace.bz2"
