I built a vm with the guest OS Windows XP. I have it running exactly the way I
need it. Now I need to move it to a computer at another location.
My plan was to build the vm and then just copy the ISO and take it to the new
system.
Specifications:
Host OS is a current/up-to-date Fedora 18
I used yum install @virtualization
I launched boxes in gnome and installed the guest system (XP)
After getting everything running to my specifications I started researching how
to move the vm to another system. I have one question:
Referring to the information at: http://libvirt.org/migration.html
"
Migration of guests between hosts is a complicated problem"
Can someone please point me to documentation stating why migration is "a
complicated problem"??
The vm is powered off. I didn't use encryption (that I'm aware of--and
I hope that doesn't bite me but I can re-install if necessary).
gnome-boxes made this a pretty-simple setup and I like it. I know with about
the same effort I can do this in VMWare, if necessary. I also know with VMWare
I can create vm images that are portable and easily transported from system to
system. If that is not the case with libvirt and gnome-boxes I'd like to
understand why.
Even though gnome-boxes made the setup fairly easy I can see where it is still
in it's infancy. I thought libvirt was more mature and seems to offer CL
access to everything I need (which I really like).
Thanks, in-advance, for your help and consideration.

The reference to "a complicated problem" deals with online migration (that is, while the guest continues to run with minimal downtime) - it is conceptually complicated, but it is a problem that is understood, and which a simple virsh command line is able to do all the pieces to make it work. Don't be scared off by that statement :) And if you do hit problems, continue to ask for help here. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
