[Bug 1481295] Re: virt-manager after upgrade: Error polling connection 'qemu:///system': internal error: could not get interface XML description: File operation failed - Failed to read (null)

[Serge Hallyn]

Actually trusty is not affected

** Also affects: virt-manager (Ubuntu Vivid)
   Importance: Undecided
       Status: New

** Also affects: netcf (Ubuntu Vivid)
   Importance: Undecided
       Status: New

** Changed in: netcf (Ubuntu Vivid)
   Importance: Undecided => High

** Changed in: virt-manager (Ubuntu Vivid)
   Importance: Undecided => High

** Description changed:

+ ==========================
+ Impact: virt-manager fails to start
+ Upstream fix: do not fail when /sys/class/net/$alias/ does not exist
+ Development fix: cherrypick of the original patch.
+ Regression potential: the patch did need some porting, so if that was not done right we could get a regression during netcf or libvirt
+ Test case:
+ 	cat .> /etc/network/interfaces  << EOF
+ iface eth0:1 inet static
+   address 192.168.1.1
+   netmask 255.255.255.0
+ EOF
+ 	virsh iface-dumpxml eth0:1
+  The virsh command should succeed and show something like
+ <interface type='ethernet' name='eth0:1'>
+ </interface>
+ 
+ ==========================
+ 
  I upgraded my machine to vivid some weeks ago and never tested this VM I
  had working before.
  
  When I try to use the virt-manager, it shows an error:
  Error polling connection 'qemu:///system': internal error: could not get interface XML description: File operation failed - Failed to read (null)

  Expected: to keep working as before
  Instead: can't list and run installed  VMs
