Hello, if I understand the API-documentation, virDomainGetInfo() should return -1 when the domain does not exists anymore, or some other problem happens. But with this code below ... if (virDomainGetInfo(domainPtr,domainInfo) == 0 ) { if (debugLevel > 15) {puts("virDomainGetInfo() returns 0");} if (domainInfo->state == VIR_DOMAIN_NOSTATE || domainInfo->state == VIR_DOMAIN_RUNNING || domainInfo->state == VIR_DOMAIN_BLOCKED || domainInfo->state == VIR_DOMAIN_PAUSED ) { return(false); } } ... I notized, virDomainGetInfo() always returns zero, even if libvirt prints an error. If I destroy a domain (xm destroy) I'll get this Message with each call of virDomainGetInfo(): "libvir: Xen Daemon error : GET operation failed:" But virDomainGetInfo() still returns zero, a bug, or did I missunderstood the API? regards Johannes
