I would like to remove a specific domU (test01--pv--guest) from my machine. I am not sure how far/to what extent to remove files. Here are the files and properties it seems I should remove:
For this task, you're actually better off using higher-level tools than you're using. Try 'lvdisplay' to list logical volumes and 'lvremove' to delete them.
HOWEVER, before you go doing that, consider going one step higher and asking Xen to do the work for you (that way, any metadata associated with the guest should also be deleted)... Oh. According to some searching, the ability for Xen to delete guests was removed. It seems the correct way to do it IS to use lvremove. Odd.

This may be due to multiple attempts to build the volumes. Is there a way to determine if all of the are useful? Ray
