Description of problem: In virt-manager, when I try to connect to the localhost qemu virtual machine I get an error message saying: Unable to open a connection to the libvirt management daemon. Verify that: - The 'libvirtd' daemon has been started Details Unable to open connection to hypervisor URI 'qemu:///session': <class 'libvirt.libvirtError'> virConnectOpenReadOnly() failed authentication failed Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/connection.py", line 306, in _open_thread self.vmm = libvirt.openReadOnly(self.uri) File "/usr/lib64/python2.5/site-packages/libvirt.py", line 144, in openReadOnly if ret is None:raise libvirtError('virConnectOpenReadOnly() failed') libvirtError: virConnectOpenReadOnly() failed authentication failed Version-Release number of selected component (if applicable): virt-manager.x86_64 0.5.3 1.fc8 libvirt.x86_64 0.4.0 4.fc8 How reproducible: Always, on two different machines running Fedora 8 and only as a non-root user. Steps to Reproduce: 1. As a regular (non-root) user, run 'virt-manager' from a terminal 2. When asked to authenticate as root click the [Run Unprivileged] button 3. In the list of virtual machines, find one that is named "localhost", has an ID of "qemu", and status "Disconnected" 4. Right click on the row that belongs to the above virtual machine 5. Select the "Connect" option from the pop-up menu Actual results: An error message pops up as described above. Expected results: No error messages popup and the localhost qemu virtual machine status changes to "Connected". Additional info: I made sure that libvirtd is indeed running when I get that error: # /etc/init.d/libvirtd status libvirtd (pid 2539) is running... Restarting libvirt is successful but does not fix this problem. Running virt-manager while authenticated as root does not exhibit this problem.
This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Hmm, this works for me. Are you still seeing this? If so, what happens when you try virsh --connect qemu:///session as both regular user and root?
Hmm, since this bug is pretty old, and I can't reproduce, I'm going to close as WORKSFORME. If you are still hitting this, please reopen and we can sort this out.
Just came across this because I hit the same problem; I'm still running f8 because I need headless administration, which I can't get to work under f9 or f10. I ran the test you requested, and saw: [root@sc1 /]# virsh --connect qemu:///session Welcome to virsh, the virtualization interactive terminal. Type: 'help' for help with commands 'quit' to quit virsh # quit [root@sc1 /]# exit exit [rim@sc1 ~]$ virsh --connect qemu:///session libvir: Remote error : authentication failed error: failed to connect to the hypervisor However I'm completely new to libvirt and qemu, not sure whether this is the normally expected behaviour, nor whether I've made some basic installation error.
