[libvirt-users] libvirt shortcomings of virsh domxml-to-native and domxml-from-native



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vmx
vmx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.
Thanks all.
