Struct MsixVectorGroup 

pub struct MsixVectorGroup {
    pub vm: Arc<Vm>,
    pub vectors: Vec<MsixVector>,
}

MSI interrupts created for a VirtIO device

Fields

vm: Arc<Vm>

Reference to the Vm object, which we’ll need for interacting with the underlying KVM Vm file descriptor

vectors: Vec<MsixVector>

A list of all the MSI-X vectors
