Whenever I try to run virt-manager I get the following error:
"Unable to connect to libvirt

here's libvirtd's status:

I just ran into the same issue. For me, I could fix it by running
| Code: | | emerge -1v libvirt libvirt-glib virt-manager libvirt-python |
and restarting the application. This is, however, on ~amd64 and thus libvirt 1.2.4. |

well a few updates later and libvirt is working now
It's only working for the root user though, If i try running virt-manager as a regular user I get the following error:
unable to connect to libvirt.
authentication failed: polkit: polkit
\56retains_authorization_after_challenge=1
Authorization required but no agent is available
I tried installing the gksu-polkit package but it wasn't very helpful or I didn't configure things properly
thanks |

I fixed the non-root issue by creating the following file:
/etc/polkit-1/localauthority/50-local.d/50-org.example-libvirt-remote-access.pkla:
[Remote libvirt SSH access]
Identity=unix-group:kvm
Action=org.libvirt.unix.manage
ResultAny=yes
ResultInactive=yes
ResultActive=yes
of course I had to add the user to the kvm group |

The following, as ShinyDoofy suggested, was all that I needed to do to fix this for me, as I already made edits to /etc//libvirt/libvirtd.conf to allow users in the kvm group to connect.
| Code: |
emerge -1v libvirt libvirt-glib virt-manager libvirt-python
|
| Code: |
# diff /etc/libvirt/libvirtd.conf.orig.bak /etc/libvirt/libvirtd.conf
81a82
> unix_sock_group = "kvm"
88c89
< #unix_sock_ro_perms = "0777"
---
> unix_sock_ro_perms = "0777"
98c99
< #unix_sock_rw_perms = "0770"
---
> unix_sock_rw_perms = "0770"
101c102
< #unix_sock_dir = "/var/run/libvirt"
---
> unix_sock_dir = "/var/run/libvirt"
129c130
< #auth_unix_ro = "none"
---
> auth_unix_ro = "none"
138c139
< #auth_unix_rw = "none"
---
> auth_unix_rw = "none"

It does not for me with the same error.
Any further measures required?

Did you add your user to the "kvm" group, or what ever group you assigned to, unix_sock_group = "kvm"? You'll have to logout and back in for your user to be effectively in this group.
Did you reboot? Or at least restart libvirt?
| Code: |
$ /etc/init.d/libvirtd restart
|
I believe restarting networking also restarts libvirt.
If you have restarted the service and you believe you are in the group then try to check.
| Code: |
$ ls -l /var/run/libvirt
total 0
drwxr-xr-x 2 root root 40 Dec 18 02:11 hostdevmgr
srwxrwx--- 1 root kvm 0 Dec 18 02:11 libvirt-sock
srwxrwxrwx 1 root kvm 0 Dec 18 02:11 libvirt-sock-ro
drwxr-xr-x 2 root root 60 Dec 18 02:11 network
drwxr-xr-x 2 root root 40 Dec 18 02:11 qemu
|
Notice the group and permissions of the libvirt-sock and libvirt-sock-ro files.
Then check your groups:
| Code: |
$ groups
wheel audio cdrom kvm cdrw users plugdev ...
|
You should be at least in the kvm group.
Also notice that I don't have any authentication in the libvirt configuration
| Code: |
auth_unix_ro = "none"
auth_unix_rw = "none"
|
That's about all I remember testing when I was first setting it up. I can't remember right at the moment what I installed. KVM is built in the kernel so you don't need to install kvm anymore. I believe I just followed this https://forums.gentoo.org/viewtopic-t-712629-start-0.html and setup a bridge and install. |

Thx mushr00m for the link and Wallsandfences for asking. I've noticed that after an emerge update that the same error was back. I currently have the following installed
| Code: |
dev-python/libvirt-python-1.2.9 USE="{-test}" PYTHON_TARGETS="python2_7 python3_3"
app-emulation/virt-manager-0.10.0-r2 USE="gnome-keyring gtk (policykit) sasl -debug" PYTHON_TARGETS="python2_7"
|
I'll see if emerging virt-manager-1.0.1 fixes this and report back on that. |

Emerging app-emulation/virt-manager-1.0.1 also introduces net-libs/libsoup-gnome-2.46.0:2.4 which fails to apply a patch during the build.
| Code: |

I'd downgrade my version of libvirt-python to try a temporary fix until newer packages become stable, but I already removed them with an emerge --sync
| Code: |
# ls /usr/portage/dev-python/libvirt-python

I tried the libvirt-python-1.2.5.ebuild from attic https://forums.gentoo.org/viewtopic-t-957354-start-0.html Although it didn't change anything. libvirt-python-1.2.5.ebuild seemed to be what was last installed from reviewing /var/log/emerge.log
I did notice after a emerge --sync a new version of libvirt. I have everything working again with the following 
| Code: |
# emerge -pv libvirt-python libvirt virt-manager
Calculating dependencies... done!

I had thought that the bug report 532410 stated that virt-manager needed to be upgraded.  and *sigh* |
