Struct kvm_rs::UserMem[−][src]

pub struct UserMem { /* fields omitted */ }

Expand description

Wrapper to safely allocate memory for guest VMs.

The underlying memory is freed automatically once the UserMem instance is dropped.

Memory can be mapped into a guest VM with Vm::set_user_memory_region.
