Hi,

Yes, driver domain has guaranteed ressources for virtual I/Os.

Today xen is configured with strict (credit) partitionning, equally important domains.
You get a fixed amount of credit with each share.

However, we do not want the share to appear excellent at the beginning (because you're alone on a node, you get full idle cpu for yourself) and degrade over time with no user idea of when it will stabilize. As people can try our servers "for a few minutes", that would be kind of lying. We want the user to experience an expected, stable performance level.

So we slightly overcommit on the credit, and as we'll get better at migrating vms accross nodes to achieve a little balance, we'll probably overcommit a little more.

Your data about CPU utilization reminds me of a couple of questions I have about Gandi's hosting service.

Do you have Xen configured to strictly partition CPU resources and not allow domains to exceed them, or can one domain take more CPU if another domain falls idle? The latter seems like a better way to ensure that CPUs stay near 100% utilization at all times.

Also, given how Xen does virtual I/O through domain 0, you should have Xen configured so that domain 0's VCPUs get dedicated physical CPUs which nothing else can run on. This will significantly improve I/O performance.

Thank you for the information.
It give me clear view about who you are and what you have done.
Great jobs!

Hi. I saw this WHT post and I'm curious if this is true, that we can't install CPanel on our share, because of the way you handle disk space...

"[...]because the disk space is mounted to a single mount, but cpanel needs certain mount points to have certain space available [...]"

This could ruin it for many people...

a/ the speed limit is the speed of 1/64 of a quadri quad core AMD
b/ We don't sell extra IPs for the moment as the RIPE is more restrictive for 'new' hosting company, but it will come.

LOL, I meant speed, not transfer!

Hi and congatulations. Two small questions... a) do you have a speed limit per share (speed, not bandwidth) and b) what is the pricing for extra IPs? Thanks!

Hi Nick, no not at the moment. We're looking at options to get something into the US, but it won't be until next year at the earliest. However our Paris data centres are very well connected, so server performance should be comparable to an East coast data centre. Thanks, Joe

Do you have any servers located in the U.S.? If so, where?

Thanks Ciprian, we're all very excited, if you use the service let us know how it goes.

Congratulation on the launch, i'm sure that all will work super.

Cheers
