Hi,

please take a look at this wiki page that i wrote a few months ago : https://github.com/Wenzel/kvm-vmi/wiki

Briefly:

• ATTACH_VM will get the vm file descriptor
• ATTACH_VCPU will get the vcpu file descriptors
• then the traps are set
• you use the vcpu file descriptor to send the GET_EVENT ioctl, and CONTINUE_VM once you are done processing it.

Regards.
