Hi everyone,
Most of our virtual machines could happily be i386 (and save a bit of
memory). I prefer the dom0s to be x86_64 for some added flexibility
for applications that do need 64bit (MySQL, memcached, varnish).
I upgraded one of our boxes to F7 to get Xen 3.1 since it's supposed
to be possible there. But it crashes pretty fast every time. I am
running the latest kernel and xen in the dom0 and just the release
tree in the domU.
Any ideas?
