Parent article: Ksplice: kernel patches without reboots

Instead, a good hosting provider will let the user choose when to reboot into a fixed kernel.

Why? Xen long had a way to solve this problem: live migration. When and how user updates kernel in VPS installation is another question...

Live migration to a different version of the kernel?

I thought that xen's migration was of a whole domU, including kernel.

You are correct. khim is probably thinking of what you do when dom0's kernel needs to be
patched.
