Look at the log of libvirt or type the following command: virsh -c qemu:///system list
Will get the error message: ERROR：authentication failed: polkit: polkit\56retains_authorization_after_challenge=1 Authorization requires authentication but no agent is available. That's an issue of libvirt configuration. [SOLVED] uncomment auth_unix_rw = "none" in /etc/libvirt/libvirtd.conf and restart libvirt-bin. Hope this can be useful for those we have the same problem. 2014-12-03 13:50 GMT+08:00 Du Jun <dj199...@gmail.com>: > dujun@dujun-OptiPlex-3020:~$ nova hypervisor-list > +----+---------------------+-------+--------+ > | ID | Hypervisor hostname | State | Status | > +----+---------------------+-------+--------+ > +----+---------------------+-------+--------+ > dujun@dujun-OptiPlex-3020:~$ nova service-list > > +----+------------------+---------------------+----------+---------+-------+----------------------------+-----------------+ > | Id | Binary | Host | Zone | Status | State > | Updated_at | Disabled Reason | > > +----+------------------+---------------------+----------+---------+-------+----------------------------+-----------------+ > | 1 | nova-conductor | dujun-OptiPlex-3020 | internal | enabled | up > | 2014-12-03T03:09:32.000000 | - | > | 2 | nova-cert | dujun-OptiPlex-3020 | internal | enabled | up > | 2014-12-03T03:09:35.000000 | - | > | 3 | nova-network | dujun-OptiPlex-3020 | internal | enabled | up > | 2014-12-03T03:09:38.000000 | - | > | 4 | nova-scheduler | dujun-OptiPlex-3020 | internal | enabled | up > | 2014-12-03T03:09:41.000000 | - | > | 5 | nova-consoleauth | dujun-OptiPlex-3020 | internal | enabled | up > | 2014-12-03T03:09:40.000000 | - | > > +----+------------------+---------------------+----------+---------+-------+----------------------------+-----------------+ > > > 2014-12-03 13:48 GMT+08:00 Du Jun <dj199...@gmail.com>: > >> Hi all, >> >> I install devstack in ubuntu12.04 and upgrade libvirt 0.9.8 to 1.2.2.
