I am trying to get a proof-of-concept type setup going...I have a
storage box and 2 xen servers...I am using file based disk that live
on the aoe device...i can run the vm from either host without
issue...when I run the live migration, the domain leaves the xm list
on host 1 and shows up on host 2 (however there is a pause for pings
of about 2 minutes?)...after it is on host 2, I can xm console and
connect to it, I checked the uptime and it was inline with what I
expected, but if I ssh into it or run "last" it hangs...can still be
pinged, but the console just hangs indefinitely...

another observation - when I go to the directory on host 1 and create
a file, I do not see it show up on host 2 unless I remount it...which
is why I have been thinking there is a syncing, caching
issue...thinking that maybe the host moves over and the disk it
accesses is not "fresh"...

I have not worked with aoe or xen before so, I am hoping there is just
a config stage I missed...

any thoughts/suggestions would be great!

thanks
lee
