If your guests are all 32-bit HVMs there should be no
problem going from 32-bit to 64-bit. There would be a problem if you had 64-bit
HVMs and wanted to go from 64-bit to 32...
If you have 32-bit DomUs you will need to make sure you
have a version of Xen that has the 32bit-on-64bit patches, I believe OpenSUSE
has a version of 3.0.4 with these, or you will have to run Xen unstable or wait
for 3.0.5.

Switching from 32-bit to 64-bit "en vivo"
this way is begging for pain.
Backing up your images and Xen setup is
*good*. I've seen reports of
people running 32-bit VM's successfully on
64-bit OS's, but I've
personally had serious trouble with running
non-rebuilt apps from 32-bit
environments in a 64-bit environment.
(Wacom devices, in particular.)
Why do you have to update your server
to 64-bit but not your VM's?
64-bit was the request of the boss for
the base operating
system, but i could install i386 also.
the
instantaneous installation was actually not for active service. but now the virtual machines
are running, and i have to switch the operating system cause we do no use fedora on our linux servers at all.
also you do not recommend
to install 64-bit? than i will install i386, i think there
would not be such a big difference,or?
thank you
Nico!
