I also have this same issue, but I got a slightly different stacktrace...
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/createnet.py", line 301, in finish
self.conn.create_network(xml)
File "/usr/share/virt-manager/virtManager/connection.py", line 743, in
create_network
self.nets[uuid] = vmmNetwork(self.config, self, net, uuid, False)
File "/usr/share/virt-manager/virtManager/network.py", line 36, in __init__
self._xml = self.net.XMLDesc(0)
File "/usr/lib/python2.6/dist-packages/libvirt.py", line 594, in XMLDesc
if ret is None: raise libvirtError ('virNetworkGetXMLDesc() failed',
net=self)
libvirtError: invalid network pointer in no network with matching uuid
Line 594 in my libvirt.py is:
if ret is None: raise libvirtError ('virNetworkGetXMLDesc() failed', net=self)
And to give some context, here's the whole function:
def XMLDesc(self, flags):
"""Provide an XML description of the network. The description
may be reused later to relaunch the network with
virNetworkCreateXML(). """
ret = libvirtmod.virNetworkGetXMLDesc(self._o, flags)
if ret is None: raise libvirtError ('virNetworkGetXMLDesc() failed',
net=self)
return ret
I tried it again with a different description for my network and got a new
stacktrace:
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/createnet.py", line 301, in finish
self.conn.create_network(xml)
File "/usr/share/virt-manager/virtManager/connection.py", line 744, in
create_network
self.nets[uuid].start()
File "/usr/share/virt-manager/virtManager/network.py", line 71, in start
self.net.create()
File "/usr/lib/python2.6/dist-packages/libvirt.py", line 620, in create
if ret == -1: raise libvirtError ('virNetworkCreate() failed', net=self)
libvirtError: cannot create bridge 'virbr0': Operation not permitted
My user is in the group "libvirtd" and I'm allowing myself to create bridges
w/o a password via sudo. From /etc/sudoers:
%libvirtd ALL=(ALL) NOPASSWD: /sbin/ifconfig, /usr/sbin/brctl, /usr/sbin/tunctl
I'm still looking for a fix or workaround to get my VM working in
bridged mode.
