[Xen-users] Re: [Xen-devel] xm migrate --live fails

Walter,
 This post IMO should go to xen-users only and not xen-devel.

that said, check the configuration in /etc/xen/xend-config.sxp especially
(xend-relocation-server yes)
(xend-relocation-hosts-allow ....

hi all,

i would like to do a live migration to another host which fails. bellow the
console output.

host    : debian squeeze 6.0.2.1 amd64
kernel  : 3.0.0
hw      : hp dl 320g5

any glue on that behavior?

by the way, I use it cause it should be a test for remus. remus doesn't work
too! the console output below as well.

thanks a lot guy's ...
