Subject Re: Getting CRAZY for having a cloud working!
Date Fri, 28 Dec 2012 08:14:13 GMT
Hallo all! Thank you for your VERY appreciated help and have happy new
year!
Vijay, could you please explain a little more detailed the steps to
remove/cleanup the host? Sorry I don't know, for example, what is a "vbd"...
I'm quite new to Linux/Xen/Xenserver/CS, sorry for asking things that maybe
are very simple...
