Hi Eduardo,
Thanks for your reply (and happy new year!). Using xen-tools certainly appears simpler, though I still can't quite get there. If in the xen-tools.conf file I specify using logical volumes, then I get the error:
"The LVM partition image creation failed to create <whatever>
aborting"
where for <whatever> I've tried using LogVol00, VolGroup00-LogVol00 and mapper/VolGroup00-LogVol00, all with no success. Here's the output from "df -h" and "lvdisplay -C":
root% df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
143G 24G 112G 18% /
/dev/sdb1 99M 36M 59M 38% /boot
tmpfs 1.2G 0 1.2G 0% /dev/shm
root% lvdisplay -C
LV VG Attr LSize Origin Snap% Move Log Copy% Convert
LogVol00 VolGroup00 -wi-ao 146.97G
LogVol01 VolGroup00 -wi-ao 1.94G
Once again, any clues and/or hints as to where I'm going wrong would be much appreciated.
Regards,
mc
