To Dan: Does SASL authentication need a connection call other than virConnectOpen{,ReadOnly}? If so then we'll need to duplicate this bug for ocaml-libvirt and add that package to the Approved Components List. Yes, you need to use virConnectOpenAuth() and provide an authentication callback to collect credentials. In the case of virt-top, since it is a CLI app, you can just pass "virConnectAuthDefault" to OpenAuth. For the OCaml API in general, you'd need to allow user specified callbacks. Moving this bug to 6.5 since ocaml-libvirt requires a change and this package is not on the ACL. This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate, in the next release of Red Hat Enterprise Linux. I'm closing this as it requires non-upstream changes, and we're not going to fix low priority stuff for RHEL 6. |
Created attachment 601105 [details] libvirtd's log with log_level=1 Description of problem: virt-top fail to connect through tcp connection with sasl authentication Version-Release number of selected component (if applicable): libvirt-0.9.10-21.el6_3.3.x86_64 virt-top-1.0.4-3.13.el6.x86_64 How reproducible: 100% Steps to Reproduce: 1.Edit /etc/sysconfig/libvirtd uncomment LIBVIRTD_ARGS LIBVIRTD_ARGS="--listen" 2.Edit /etc/libvirt/libvirtd.conf listen_tcp =1 auth_tcp = "sasl" 3.Add a user named "fred", and setting his password as "redhat" # saslpasswd2 -a libvirt fred Password: xxxxxx Again (for verification): xxxxxx 4. #service libvirtd restart 5. #service iptables stop 6. virsh -c qemu+tcp://$ip/system 7. virt-top -c qemu+tcp://$ip/system --debug /tmp/virt-top-debug Actual results: 1. Step 6 works well 2. Step 7 fails with following error: -------------------------------------------------------------------------------------- libvir: RPC error : authentication failed: Failed to start SASL negotiation: -4 (SASL(-4): no mechanism available: No worthy mechs found) libvirt: VIR_ERR_AUTH_FAILED: VIR_FROM_RPC: authentication failed: Failed to start SASL negotiation: -4 (SASL(-4): no mechanism available: No worthy mechs found) -------------------------------------------------------------------------------------- Expected results: 1. virt-top could work well. Additional info: 1. After step 7, debug file wasn't created, so I cannot provide it. Only attach the libvirtd's log
