Bug 305407 – Attempting to connect to hpyervisor via virt-manager, libvirt fails to access any hypervisor, (qemu, qemu-kvm, xen) with error, no hypervisor driver available; virt-manager-0.8.2 and libvirt-0.7.5

• Status: RESOLVED NEEDINFO
• Product: Gentoo Linux

[Description Ian Delaney (RETIRED) 2010-02-16 16:05:26 UTC]

Freshly emerged instance of virt-manager and libvirt, the hypervisor cannot be connected.  Both these report error, no hypervisor driver available for qemu/qemu-kvm/xen.  The sub-program virsh presents with the same deficit.

idella@gentoo64 ~ $ sudo virsh
Welcome to virsh, the virtualization interactive terminal.

Type:  'help' for help with commands
       'quit' to quit

virsh # connect qemu:///
error: Failed to connect to the hypervisor
error: no hypervisor driver available for qemu:///

idella@gentoo64 ~ $ sudo virt-manager

yields the full message when attempting to connect via the listed localhost/qemu///

no hypervisor driver available for qemu:///system


gentoo64 idella # virt-manager

yields

Error starting Virtual Machine Manager: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/ for information. (Details -  1: Failed to get connection to session: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.)

Now, some helpful debugging.  To prove this is a flawed package, 
gentoo64 / # gdb --args libvirtd

Problem !.  Can't parse XML syscalls.  Package was compiled with all required USE flags plus xml.,also unmerged and re-emerged with -xml, same output.

and

(gdb) run

I've got the same result on a gentoo 32 and this gentoo amd_64.

Reproducible: Always

Steps to Reproduce:
1.emerge virt-manager libvirt (all flags included)
2.Invoke virt-manager, invoke virsh, attempt to connect to a hypervisor.
sudo virt-manager,  or sudo virt-manager -c qemu:///
sudo virsh -c qemu:///   (without sudo, permission refused, which should also not happen since permission levels for use have been set.
3. No more.  deficit done

Actual Results:  
As previously stated, perhaps that goes here. Neither libvirt nor virt-manager can connect to the hypervisor (driver). Fails to connect.

Expected Results:  
To connect to hypervisor via virt-manager or via virsh.
e.g.  sudo virsh -c qemu:///system,
sudo virt-manager -c qemu:///

It can connect to an added driver, test:///default.
Once connected, virt-manager's installer also fails a second test.
One selecting CDrom install, it can't proceed past that wizzard window.
Once selecting a .iso image, it then begins an install, but as it does in debian distros, fails to connect to the virt-manager vnc console, error Console not active for guest.  All in all, completely unusable.

Paste the output of: emerge -pv libvirt virt-manager

idella@gentoo64 ~ $ sudo emerge -pv libvirt virt-manager

These are the packages that would be merged, in order:

                        ... done!
[ebuild   R   ] app-emulation/libvirt-0.7.5  USE="libvirtd lxc network nls python udev -avahi -caps -iscsi -lvm -nfs -numa -one -openvz -parted -phyp -policykit -qemu* -sasl (-selinux) -uml -virtualbox -xen*" 0 kB
[ebuild   R   ] app-emulation/virt-manager-0.8.2  USE="-gnome-keyring" 0 kB

Total: 2 packages (2 reinstalls), Size of downloads: 0 kB

Now to note, on emerging these initially in the newest 64 version, I found this list of required use flags and pasted ensured I pasted them into make.conf.  You can observe anyway, the above entry now includes -qemu* and -xen*; new, I last installed them with the above,

USE="qemu kvm xen" emerge libvirt,   only libvirt.  The kvm seems to have made no such impact.  virt-manager can connect ok now, virtinst is troubled.

I am getting this bug too, with the latest KVM and libvirt on amd64.
