Xen users - Nov 2008 - Question on installing Xen...

I have two main partitions on my computer: root and home. Home changes size a
lot more often and is much more likely to run out of space. So , I have a few
questions on different options:

1. If I install Xen on "root" partition, is that a security risk?
2. Can I create a new partition with part of "root" and part of
"home"?
3. How much room does Xen require? And does it have problems running on certain
types of partitions?

Thanks!

1. It is only as safe as you make it. I usually install in /opt/.  
According to the FHS that is where add-on applications should be  
installed. Try to never install anything in the / directory if  
possible. For a good look at what "should" go where, look at this:   
http://tldp.org/LDP/Linux-Filesystem-Hierarchy/html/index.html

2. Not without some pain if you have already installed and used all  
available space. If you used LVM and have free space according to  
vgdisplay then you can create an LV and install it there.

3.
   a. It needs enough room for xen itself and the kernel plus a few  
utilities it downloads and to build. Be safe, give it enough.

   b. None that I have heard of.

Hope that helps,

Jon
