Hi,all. we use libvirt to manage some host and vms on vmware hypervisor.I have found the libvirt there are some shortcomings . Such as virsh domxml-to-native and domxml-from-native .I have reviewed the libvirt source --src/vmx/vmx.c, code as follows : libvirt0.9.13源码xml 转化成vmxvmx转化成xml /* def:os.arch -> vmx:guestOS */ if (def->os.arch == NULL || STRCASEEQ(def->os.arch, "i686")) { virBufferAddLit(&buffer, "guestOS = \"other\"\n"); } else if (STRCASEEQ(def->os.arch, "x86_64")) { virBufferAddLit(&buffer, "guestOS = \"other-64\"\n"); } else { VMX_ERROR(VIR_ERR_INTERNAL_ERROR, _("Expecting domain XML attribute 'arch' of entry 'os/type' " "to be 'i686' or 'x86_64' but found '%s'"), def->os.arch); goto cleanup; }/* vmx:guestOS -> def:os.arch */ if (virVMXGetConfigString(conf, "guestOS", &guestOS, true) < 0) { goto cleanup; } if (guestOS != NULL && virFileHasSuffix(guestOS, "-64")) { def->os.arch = strdup("x86_64"); } else { def->os.arch = strdup("i686"); } if (def->os.arch == NULL) { virReportOOMError(); goto cleanup; } Vmware support many guestOS types like "windows7srv-64 ",If I use 64-bit Windows virtual machine, other-64 this type is not correct. NIC e1000 system can not be used . So I suggest to The libvirt improve the vmware support, especially the mutual transformation of the xml and vmx format guestOS only one parameter.
