Description Eli Billauer 2011-01-28 15:24:51 UTC

Description of problem:

When /etc/sysconfig/network-scripts contains an ifcfg file corresponding to dialup inteface (in my case, ppp0 for ADSL dialup), and the interface doesn't exist, the system log (/var/log/messages) gets filled with messages like these:

Jan 28 16:58:23 myhost libvirtd: 16:58:23.005: error : interfaceGetXMLDesc:355 : internal error could not get interface XML description (netcf: NETLINK socket operation failed - couldn't find ifindex for interface `ppp0`)

Version-Release number of selected component (if applicable):

libvirtd --version responds 0.8.2. I know it's outdated (so is Fedora 12) but I haven't seen any hint about this being fixed since.

How reproducible: Always.

Steps to Reproduce:
1. Create a dialup interface, but keep it down
2. Run virt-manager with the interface down.
3. Check /var/log/messages
 
Actual results:
A lot of messages.

Expected results:
No messages.

Sorry this never received a response. virt-manager + libvirt interfaces used to be a lot noisier... I suspect this is fixed nowadays, so closing. If anyone can still reproduce with modern libvirt, please reopen, and provide the /etc/sysconfig/network-scripts entry that is causing the issue
