[Libvir] Re: libvirt adding new methods to the xenUnifiedDriver

hi I am messing with libvirt and I need to add some methods to the xenUnifiedDriver structure. I do it this way: (currently #ifdef-ed out) struct xenUnifiedDriver { virDrvOpen open; virDrvClose close; virDrvGetVersion version; virDrvGetHostname getHostname; virDrvGetURI getURI; virDrvNodeGetInfo nodeGetInfo; virDrvGetCapabilities getCapabilities; virDrvListDomains listDomains; #if 0 virDrvListDatastores listDatastores; virDrvListSyspreps listSyspreps; #endif .... with the #if switched to off I am seeing some problems in xenUnifiedDomainGetInfo(). it basically iterates through array of driver structures to find out suitable domainGetInfo() method. When I flip the #if to 1 the driver structures get redefined causing xenUnifiedDomainGetInfo() to not find any suitable driver.

code stuffed with debugging printfs: #if 0 case: priv->opened[i]: 0 drivers[i]->domainGetInfo: 0x2aaaaaae0c10 priv->opened[i]: 1 drivers[i]->domainGetInfo: 0x2aaaaaaec2c0 Domains 0: 2 CPUs #if 1 case: priv->opened[i]: 0 drivers[i]->domainGetInfo: (nil) priv->opened[i]: 1 drivers[i]->domainGetInfo: (nil) priv->opened[i]: 0 drivers[i]->domainGetInfo: 0x2aaaaaae7400 priv->opened[i]: 0 drivers[i]->domainGetInfo: (nil) priv->opened[i]: 1 drivers[i]->domainGetInfo: (nil) Failed to get informations for Domain 0 as you can see the "drivers" (xenHypervisorDriver etc.) got redefined... any idea why? or whats going on? thnx for any possible help, if you cannot help me could you please forward this mail to the appropriete place?
