I''ve done something apparently, but can''t for the life of me figure out what. Perhaps someone can help: I have an LVM based domU which has been working without problem for weeks. I made some final changes to it last week, shut it down and ran the following to create a backup image: dd if=/dev/VolGroup00/wspd of=mail2.img bs=1M At least this is the only thing I can remember doing. Since then when I try to start it, I get the following: [root@xen3 xen]# xm create wspd -n Using config file "./wspd". Traceback (most recent call last): File "/usr/bin/pygrub", line 651, in ? fs = fsimage.open(file, get_fs_offset(file)) IOError: [Errno 95] Operation not supported No handlers could be found for logger "xend" Error: Boot loader didn''t return any data! Usage: xm create <ConfigFile> [options] [vars] Create a domain based on <ConfigFile>. My config file looks like this: name = "wspd" uuid = "e0dfbc97-4049-c17f-1a86-957dff290125" maxmem = 384 memory = 384 vcpus = 1 bootloader = "/usr/bin/pygrub" on_poweroff = "destroy" on_reboot = "restart" on_crash = "restart" vfb = [ "type=vnc,vncunused=1,keymap=en-us" ] disk = [ "phy:/dev/VolGroup00/wspd,xvda,w" ] vif = [ "mac=00:16:3e:29:99:cf,bridge=xenbr0" ] Hints of any kind are appreciated. -- ------------------------------------------------------------------------ Charles Farinella Appropriate Solutions, Inc.

As an aside, I have a number of live Xen domU servers running, but I always have trouble building new ones. All are CentOS 5 and I don''t know if the issue is related to Xen, CentOS or operator ignorance. I''ll have to do some reading. Thanks to all for the help. -- ------------------------------------------------------------------------ Charles Farinella Appropriate Solutions, Inc.
