and again a day ahead or something?
If the prospect of being powered off for half an hour or so a month
from now is not acceptable to anyone, then we can most likely move
their VM to another server ahead of time - one that we know won't be
involved in the move. By semi-live migration if necessary. That's
the only per-customer thing we can do and it's extra work so we will
only do it if people ask for it. There isn't enough spare capacity
to do it for everyone so doing migration as default for everyone is
not an option. But happy to do it on a case by case basis.
Your thoughts?
Hi Andy,
Nothing I run will worry about a half hour of downtime but I would want
to know exactly when it is so I can plan.
All I would want to know is how to easily find out whether my VM will be
on that host *when the move is going to happen* since rolling upgrades
may move it between physical kit at some point before then.
