Bug 532614 – No connection possible anymore

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Sebastian Kricner 2014-12-15 03:53:24 UTC]

Connection attempts to libvirtd fail with following error:

Mit libvirt konnte nicht verbunden werden.

'module' object has no attribute 'VIR_CRED_AUTHNAME'

Libvirt URI is: qemu:///system

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/connection.py", line 1002, in _open_thread
    self.vmm = self._try_open()
  File "/usr/share/virt-manager/virtManager/connection.py", line 980, in _try_open
    [[libvirt.VIR_CRED_AUTHNAME,
AttributeError: 'module' object has no attribute 'VIR_CRED_AUTHNAME'

This might be a regression of app-emulation/libvirt.
Used version of virt-manager: 0.10.0

Reproducible: Always

Steps to Reproduce:
1. Upgrade to latest ebuilds of libvirt and virt-manager
2. Also problem connecting as normal user with virsh -c qemu+ssh:///system
3. Configuration uses socket authorization by group and socket file permissions.
   - No authentication used.
Actual Results:  
Not possible to use virt-manager

Expected Results:  
Able to use virt-manager in conjunction with libvirtd

[Comment 2 Sebastian Kricner 2014-12-15 04:09:09 UTC]

virsh -c qemu+ssh:///system was not the right way to use virsh.

[Comment 3 Sebastian Kricner 2014-12-15 04:18:08 UTC]

Issue with virt-manager still applies.
Ignore the brabble about virsh.

libvirtd.conf:

unix_sock_group = "libvirt"
unix_sock_ro_perms = "0777"
unix_sock_rw_perms = "0770"
unix_sock_dir = "/var/run/libvirt"
auth_unix_ro = "none"
auth_unix_rw = "none"

[Comment 7 Sebastian Kricner 2014-12-15 16:48:11 UTC]

Whats interesting is, upon starting virt-manager and going into "Help" - "Info" Dialog ist shows:

Virtual Machine Manager
0.10.0

But:

virt-manager --version
1.1.0

Same problem.

Must have to do something with the patches introduced the last days due to some CVE. Might also be a upstream issue.
