problem

start from line 315 in HypervisorGuruBase.java

if (vmProfile.getTemplate().getBits() == 32) {
    to.setArch("i686");
} else if("s390x".equals(System.getProperty("os.arch"))) {
    to.setArch("s390x");
} else {
    to.setArch("x86_64");
}

If host machine is arm, it goes to to.setArch("x86_64"). "to" refers to "VirtualMachineTo", and it will be passed to "LibvirtComputingResource" and then to "LibvirtVMDef" later, thus affecting the generation of <os><type arch=...>. Since this part is hard-coded here, the method "LibvirtVMDef.setGuestArch("aarch64")" has no chance to be called at all.
