Hello,
In Xen hypervisor, what is "HVM with PV driver" and "PVHVM"? Both are same?
Thank you.
from: https://meta.stackexchange.com/questions/19665/the-help-vampire-problemIt's all too easy to blame Help Vampires for problems in Stack Overflow.
But it's not them, it's us. The people who feed them.
If the question is an exact duplicate, let them know it's an exact duplicate.
If the question is a trivial question about something from the standard library, don't forget to link to the standard library documentation while answering the question.
If someone asks "Why doesn't this code work?", and the debugging is trivial, don't just do the trivial debugging for them. Show them how they can debug it themselves (for example, tell them about warning flags).

Just use the KVM -> problem solved

Why KVM? I prefer VirtualBox over KVM.

It really is just a matter of preferences, you don't tell us why you prefer Virtual Box over KVM ? One reason many of use do not use Virtual Box is that it is not in the Debian repositories, and is not opensource. So maybe tell us your reasons ?
And Amazon has nothing to do with it either, I all ready said, on Debian, and also other OS, VirtualBox is not in the repositories.Why you use KVM instead of Xen? Is it because of Amazon switched to KVM
I don't know why you want to start a war.
For example, google "Xen Live Patching"

But also QEMU/KVM simply works much better the VB, in my opinion,....but really, use what ever you want, everyone has their preferences.I don't know why you want to start a war.
Who said anything about starting a war ? Why do you say that ? Is that why you asked the original questions ? Just to start grudging and arguing ?
For example, google "Xen Live Patching"
Why would I want to do that ? I have no interest in Xen, ..

KVM is simply the fastest virtualization technology available in the market today - and it's very unlikely that there will be anything faster in the foreseeable future.
Anyway, it's really funny to see how many companies are completely misunderstanding virtualization -> often they are deploying entire OS in a VM just to run a single application - instead of using containers/slices or just ordinary processes, which are also virtualized by the kernel ...

It depends on how will You look at it.
Since version ~2.6 the Linux kernel works just like the type-1 hypervisor, that is, it just manages virtualized containers, just like XEN, but without the need to use XEN as a backbone. From this point of view, the KVM is just another container managed by the kernel, working in a 'HVM'-like mode.
This approach allows f.e. for better I/O scheduling, especially if the containers are sharing the same storage - and this is a primary reason why KVM beats XEN under heavy I/O load.
No doubt there is a lot of people who get used to XEN, and XEN is still used to manage many production servers - so it will be developed and supported in the future -> but it's no longer needed.
As for VirtualBox, it's deadly slow when using its the default hypervisor, f.e.:

Obviously, VirtualBox can be configured to use KVM - but then, what would be the reason to use VirtualBox at all?
Return to System configuration
