Xen project Mailing List

Hello,

So I followed the guide http://wiki.xen.org/wiki/Xen_4.2_Build_From_Source_On_RHEL_CentOS_Fedora

and built/installed Xen from source, using grub2-mkconfig to rebuild grub and was able to reboot

Dom0 with Xen successfully.

Then I installed packages for virt-manager.

# yum install libvirt-daemon-xen python-virtinst libvirt-daemon-config-network libvirt-daemon-driver-network virt-manager virt-viewer

Everything got installed except for one package. Got an error message "No package libvirt-daemon-driver-network available."

Now when I start virt-manager, it is unable to connect to Xen and fails with the following error.

# virt-manager

Unable to connect to libvirt.

unable to connect to 'localhost:8000': Connection refused

Verify that:

- A Xen host kernel was booted

- The Xen service has been started

Libvirt URI is: xen:///

Traceback (most recent call last):

File "/usr/share/virt-manager/virtManager/connection.py", line 1027, in _open_thread

self.vmm = self._try_open()

File "/usr/share/virt-manager/virtManager/connection.py", line 1009, in _try_open

flags)

File "/usr/lib64/python2.7/site-packages/libvirt.py", line 102, in openAuth

if ret is None:raise libvirtError('virConnectOpenAuth() failed')

libvirtError: unable to connect to 'localhost:8000': Connection refused

# xm list and # xm info work fine. This means xend is running right ?

Did some searching, found an old thread http://old-list-archives.xenproject.org/xen-users/2010-06/msg00880.html

Added (xend-unix-server yes) to xen configuration file xend-config.sxp
and added export VIRSH_DEFAULT_CONNECT_URI="xen:///" to root's .bashrc.

Still no luck.

This might help, # rpm -qa | grep libvirt

libvirt-daemon-xen-0.9.11.9-1.fc17.x86_64

libvirt-daemon-0.9.11.9-1.fc17.x86_64

libvirt-0.9.11.9-1.fc17.x86_64

libvirt-python-0.9.11.9-1.fc17.x86_64

libvirt-daemon-config-network-0.9.11.9-1.fc17.x86_64

libvirt-daemon-config-nwfilter-0.9.11.9-1.fc17.x86_64

libvirt-client-0.9.11.9-1.fc17.x86_64

So in summary,

Built and installed from source Xen 4.1.5, on Fedora 17.

Can boot into Xen Dom0, xm works, xend running, But virt-manager unable to connect to Xen!

Please help.

I have tried to give as much info as I could. Do let me know if you need more info.

That is possible, I guess... I'm sorry, but as I said already, I know
nothing of using both the packaged version of Xen and libvirt on Debian
or Ubuntu. :-(

Well, without the details, it's hard to say anything more than what has
been said already. I do test Xen on Fedora regularly, and that includes
basic libvirt (both virt-install and virt-manager) operations. Both
Fedora 18 and Fedora 19 work pretty well for me, and I haven't seen any
issues in connecting to libvirtd.

If you get the chance to try it again, feel free to ask for help,
providing all the needed details on what is that your are seeing, either
here, or on xen@xxxxxxxxxxxxxxxxxxxxxxx, or on
virt@xxxxxxxxxxxxxxxxxxxxxxx, or on libvir-list@xxxxxxxxxx, depending on
where you think the problem could be. :-)

Regards,

Dario
