In a previous message you said your logs contained "BLKTAPCTRL[2795]:
blktapctrl_linux.c:92: couldn't find device number for 'blktap0'". This
indicates the tools looked for blktap0 information in
/sys/class/xen/blktap0/dev and /sys/class/misc/blktap0/dev and found it in
neither place. Which would indicate something is missing or wrong with the
dom0 kernel setup. Xen and tools should not need rebuilding to fix this.
