Hi!<BR>
<BR>
Today's not my most successful day ;) <BR>
<BR>
I'm now discovering the following problem: I try to "xm create mysqlprx01 vminstall=1 -c" a new XenU. I'm getting the busybox but "unionfs mount failed". Why? Does somebody know why ROOTPATH is empty? Mr Google didn't gave me an appropriate answer :(<BR>
