Hello!
I have upgraded all libvirt packages to version 3.5.0-655.1 and restarted host.
This is the current default network config:
ld4004:~ # virsh net-dumpxml default
<network connections='1'>
<name>default</name>
<uuid>f511d113-d7d1-4714-ad2b-be29ef8f7fc4</uuid>
<forward dev='br0' mode='nat'>
<nat>
<port start='1024' end='65535'/>
</nat>
<interface dev='br0'/>
</forward>
<bridge name='virbr0' stp='on' delay='0'/>
<mac address='52:54:00:f5:5f:ca'/>
<domain name='local.net' localOnly='yes'/>
<ip address='192.168.100.1' netmask='255.255.255.0'>
<dhcp>
<range start='192.168.100.10' end='192.168.100.254'/>
</dhcp>
</ip>
</network>
What do I need to configure in order to have NSS working?
