What is provided with the Xen Tools and why do I need them?

What is provided with the Xen Tools and why do I need them?

[Nick Garnett]

There are many references to the "Xen Tools", but I can't find any
documentation that explains what the "Xen Tools" are.

What is provided with the Xen Tools and why do I need them?

The Xen tools are used to create and manage virtual machines. See
xl(1)[0] for more information.

Is "xl" the application that is installed following the "Xen ARM with
Virtualization Extensions/CrossCompiling" page, "Build arm64 tools" section?

I was able to install the "xen-tools" package with no issues, following the
"xen-tools – a straightforward VM provisioning/installation tool" page
("https://blog.xenproject.org/2012/08/31/xen-tools-a-straightforward-vm-prov
isioninginstallation-tool/").

Does that package provide the only "Xen Tools" that are necessary?

Hello,

Please avoid top-posting, it breaks the flow of the conversation.

Yes, those are the tools I was referring to.

OK, this is not the tools I was referring to. Sadly someone decided to
create a completely different application that's used for provisioning
vm images, and decided to name it xen-tools. This is not mandatory in
order to run a Xen Dom0.

No.

So, the "xen-tools" package does not provide all of the tools that are
necessary.  It provides xl/xm, so what else is necessary?

OK, not top-posting.  Using a mail tool that puts replies at the top.

I suppose so.

No. "xen-tools" (note the hyphen) is a third-party project to help you
provision VMs.

"Xen tools" should be read as "the userspace tools component of Xen
hypervsior project", which is part of the xen source code.

The confusion is a bit unfortunate.

I assume you are trying to cross-compile Xen for arm64, so you need to
build the tools as listed here:

https://wiki.xenproject.org/wiki/Xen_ARM_with_Virtualization_Extensions/CrossCompiling#Build_arm64_tools
