virtualization - Why are many "bare kernel+app" solutions targetting xen? -


There are several such projects that produce complete images from your app to boot on XN as a machine. For example, and others.

Why is Xen the default Hypervisor for them? Does it provide some interface that makes these projects easy (as opposed to KVM, VmWare, etc.), or is it the only project developers' choice?

gives the following answer:

  • Xenâ in the cloud € ™ s Footprint: AWS, Racspace Folk Cloud and many others are running Xen, first means Xen means.

  • Zen Paravribilization offers guests a very easy and ideal interface for I / O. On the contrary, the KVM VIRTIO interface looks like the underlying hardware, as a result, Xen is easy to turn off the language runtime.

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon.
