Which two statements are correct?

• A.kvm provides a software package called Linux Integration Services (LIS) that provides integration between the OS running in thekvmvirtual machine and the physical host.
• B.kvmis an open source hypervisor, which provides full virtualization with hardware-assisted virtualization. It does not support paravirtualized devices.
• C.There are twokvmmodules: akvmmodule that provides the core virtualization infrastructure and akvm_hwmodule that ensbles x86 hardware virtualization extensions (Intel VT or AMD-V).
• D.Thekvmhypervisor in Oracle Linux is managed withlibvirtAPI and tools built forlibvirt, such asvirt-managerandvirsh.
• E.kvmis considered both a type-1 and type-2 hypervisor because it turns the Linux kernel into a bare-metal hypervisor but the OS running on the virtualization host is a full OS.
