Thanks for confirming that the live migration issue isn't just me.
I'm just getting my head round LVM at the moment, thinking live migration would be an excellent solution for getting domU's off a failing server, so it's a shame it's not supported.
I don't quite get why though, because the data seems to copy, the configuration gets loaded, yet something isn't quite right and the server streams errors.
If I went back to disc images, do you know if live migration works? I guess that's where I diverged from your tutorial, to my peril.
I look forward to reading your article on iSCSI - sounds fascinating.
