[libvirt-users] SSH from host to domain using hostname

[c.monty at web.de]

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?

THX
