My mistake and sorry for the noise on messages #10/15/20.<br><br>Relevant information to this bug is the patch does resolve the issue in xen-utils-4.0 (4.0.1~rc6-1) aswell! After applying the patch, which is not applied in the package: xen-utils-4.0 (4.0.1~rc6-1) I was able to start the xend daemon on my Debian Squeeze AMD64 system without getting the error: 'NoneType' object has no attribute 'rfind'.<br><br>Works when (in xend-config.sxp):<br><br>1) The configuration is the default in xen-utils-4.0 (4.0.1~rc6-1).<br><br>2) After changing:<br><br>#(xend-tcp-xmlrpc-server no)<br>(xend-tcp-xmlrpc-server yes)<br><br>Without further configuring <br># Address and port xend should use for the legacy TCP XMLRPC interface,<br># if xend-tcp-xmlrpc-server is set.<br>#(xend-tcp-xmlrpc-server-address 'localhost')<br>#(xend-tcp-xmlrpc-server-port 8006)<br><br># SSL key and certificate to use for the legacy TCP XMLRPC interface.<br># Setting these will mean that this port serves only SSL connections as<br># opposed to plaintext ones.<br>#(xend-tcp-xmlrpc-server-ssl-key-file xmlrpc.key)<br>#(xend-tcp-xmlrpc-server-ssl-cert-file xmlrpc.crt)<br><br><br><br>Without the patch, the issue is still confirmed in version 4.0.1~rc6-1 with the following trace from /var/log/xend/xend.log<br><br>[2010-09-05 11:59:52 7673] INFO (SrvDaemon:332) Xend Daemon started<br>[2010-09-05 11:59:52 7673] INFO (SrvDaemon:336) Xend changeset: unavailable.<br>[2010-09-05 11:59:53 7673] DEBUG (pci:1253) Caught TypeError 'ord() expected a character, but string of length 0 found'<br>[2010-09-05 11:59:53 7673] DEBUG (XendDomainInfo:149) XendDomainInfo.recreate({'max_vcpu_id': 1, 'cpu_time': 2000696342543L, 'ssidref': 0, 'hvm': 0, 'shutdown_reason': 255, 'dying': 0, 'online_vcpus': 2, 'domid': 0, 'paused': 0, 'crashed': 0, 'running': 1, 'maxmem_kb': 17179869180L, 'shutdown': 0, 'mem_kb': 3206400L, 'handle': [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0], 'blocked': 0, 'name': 'Domain-0'})<br>[2010-09-05 11:59:53 7673] INFO (XendDomainInfo:167) Recreating domain 0, UUID 00000000-0000-0000-0000-000000000000. at /local/domain/0<br>[2010-09-05 11:59:53 7673] DEBUG (XendDomain:464) Adding Domain: 0<br>[2010-09-05 11:59:53 7673] DEBUG (XendDomain:398) number of vcpus to use is 0<br>[2010-09-05 11:59:53 7673] DEBUG (XendDomainInfo:1891) XendDomainInfo.handleShutdownWatch<br>[2010-09-05 11:59:53 7673] WARNING (XendAPI:705) API call: VBD.set_device not found<br>[2010-09-05 11:59:53 7673] WARNING (XendAPI:705) API call: VBD.set_type not found<br>[2010-09-05 11:59:53 7673] WARNING (XendAPI:705) API call: session.get_all_records not found<br>[2010-09-05 11:59:53 7673] WARNING (XendAPI:705) API call: event.get_record not found<br>[2010-09-05 11:59:53 7673] WARNING (XendAPI:705) API call: event.get_all not found<br>[2010-09-05 11:59:53 7673] WARNING (XendAPI:705) API call: VIF.set_device not found<br>[2010-09-05 11:59:53 7673] WARNING (XendAPI:705) API call: VIF.set_MAC not found<br>[2010-09-05 11:59:53 7673] WARNING (XendAPI:705) API call: VIF.set_MTU not found<br>[2010-09-05 11:59:53 7673] WARNING (XendAPI:705) API call: debug.get_all not found<br>[2010-09-05 11:59:53 7673] INFO (XMLRPCServer:156) Opening Unix domain socket XML-RPC server on /var/run/xend/xen-api.sock;
