I'm trying to get the hypervisor to execute a
user-given code without recompiling the hypervisor. This
is just for research purpose.
Would appreciate some guidelines of the possible ways
to go about it.
Cheers,
Anh.
Recompile Xen, and run it in a VM if you find hardware is taking too
long to reboot.
There is no existing way of loading code into Xen at runtime. The
best which exists is the kexec crash path, but Xen will partially
shut down when exiting on this path.
