[libvirt] ESX error while freeing inherited objects
by Ata Bohra 02 Jan '13

02 Jan '13

Hi All, Freeing of an object having inheritance depth >=2 throws an error such as:" internal error Call to esxVI_<grand_parent>_Free for unexpected type 'Child'. " For instance: Below code snippet is from esx_vi_generator.input (modified) object VirtualDevice Int key r Description deviceInfo o VirtualDeviceBackingInfo backing o VirtualDeviceConnectInfo connectable o Int controllerKey o Int unitNumber o end object VirtualController extends VirtualDevice Int busNumber r Int device ol end object VirtualIDEController extends VirtualController end object VirtualDeviceConfigSpec VirtualDeviceConfigSpecOperation operation o VirtualDeviceConfigSpecFileOperation fileOperation o VirtualDevice device r end object VirtualMachineConfigSpec... VirtualDeviceConfigSpec deviceChange ol..end On free of "VirtualMachineConfigSpec", I hit below error:"libvir: ESX Driver error : internal error Call to esxVI_VirtualDevice_Free for unexpected type 'VirtualIDEController'" But if I remove VirtualController and include its fields directly to VirtualIDEController, error is resolved. Please let me know if I'm missing anything, else, it seems like a bug with generated code. While debugging the error seems to come from: esx_vi_types.c: /* * Macros to implement dynamic dispatched functions */#define ESX_VI__TEMPLATE__DISPATCH(_actual_type, _actual_type_name, __type, \ _dispatch, _error_return) \ switch (_actual_type) { \ _dispatch \ \ case esxVI_Type_##__type: \ break; \ \ default: \ virReportError(VIR_ERR_INTERNAL_ERROR, \ _("Call to %s for unexpected type '%s'"), \ __FUNCTION__, _actual_type_name); \ return _error_return; \ } Thanks!Ata

[libvirt] virsh "net-create" explanation
by Bilal Ahmad 28 Dec '12

28 Dec '12

Hi all, I am new to libvirt and started looking at the source code. While tracing back the virsh command "net-create", I got stuck into a loop and I would really like someone to explain how this works. In the virsh-network.c, from: network = virNetworkCreateXML(ctl->conn, buffer); I traced back to: if (conn->networkDriver && conn->networkDriver->networkCreateXML) { virNetworkPtr ret; ret = conn->networkDriver->networkCreateXML(conn, xmlDesc); Then I traced back to the following struct to find how networkCreateXML is working: struct _virNetworkDriver { const char * name; /* the name of the driver */ virDrvOpen open; virDrvClose close; virDrvNumOfNetworks numOfNetworks; virDrvListNetworks listNetworks; virDrvNumOfDefinedNetworks numOfDefinedNetworks; virDrvListDefinedNetworks listDefinedNetworks; virDrvListAllNetworks listAllNetworks; virDrvNetworkLookupByUUID networkLookupByUUID; virDrvNetworkLookupByName networkLookupByName; virDrvNetworkCreateXML networkCreateXML; >From the above code, I located the definition of virDrvNetworkCreateXML and found the following: typedef virNetworkPtr (*virDrvNetworkCreateXML) (virConnectPtr conn, const char *xmlDesc); This is where I am unable to trace back to any other code. Can someone please explain the code with typedef above and where is the definition of the function this function pointer is pointing to? I want to get to the root of the networkCreateXML function and how it exactly works. Can someone please explain? Thanks a lot, Bilal

Please try. My guess is that this is a libvirt bug added by http://libvirt.org/git/?p=libvirt.git;a=commitdiff;h=0211fd6e04cdc402da2081… in libvirt 1.0.1. More authoritative answer is expected by those added to the CC line.

[libvirt] [PATCH] ESX: append CURL headers to fix serviceContent entities
by Ata E Husain Bohra 26 Dec '12

26 Dec '12

It seems with current SOAP header the call to retrieve "serviceContent" object does not populate all available references (for instance: ovfManager). The host exposes details of these Managed Object References (MoBs) if header is appended with "SOAPACtion" field.
