* But first, how does our Guest contact the Host to ask for privileged

2007-10-21 20:56:26 -04:00

* operations? There are two ways: the direct way is to make a "hypercall",
|
|
|
|
* to make requests of the Host Itself.

* We use the KVM hypercall mechanism, though completely different hypercall
|
|
|
|
* numbers. Seventeen hypercalls are available: the hypercall number is put in
|
|
|
|
* the %eax register, and the arguments (when required) are placed in %ebx,
|
|
|
|
* %ecx, %edx and %esi. If a return value makes sense, it's returned in %eax.

* Grossly invalid calls result in Sudden Death at the hands of the vengeful
|
|
|
|
* Host, rather than returning failure. This reflects Winston Churchill's
