Logs from virt-manager
Description of problem:
If "ipv6.disable=1" is specified in kernel cmdline, virt-manager is stuck at "Connecting..." and "virsh list" hangs with no output. This happens even when there is no network connection.
Version-Release number of selected component (if applicable):
Fedora 19 x86_64
Steps to Reproduce:
1. Add "ipv6.disable=1" to your kernel cmdline
2. Start "virt-manager" or "sudo virsh list"
virt-manager hangs at "connecting..." to qemu
virsh list hangs and does nothing.
virt-manager and virsh should work as usual.
I can reproduce with libvirt git, the source seems to be that our first firewalld-cmd hangs. I can reproduce manually with:
sudo /bin/firewall-cmd --direct --passthrough ipv6 -n -L FORWARD
Should be fixed upstream with:
firewalld-0.3.5-1.fc20 has been submitted as an update for Fedora 20.
firewalld-0.3.5-1.fc19 has been submitted as an update for Fedora 19.
* should fix your issue,
