DHCPv6 with qemu/kvm

[Ed Greshko <ed.greshko@xxxxxxxxxxx>]

Hi,

I've used virsh to edit my networking configuration as so...

<network>
  <name>default</name>
  <uuid>b53f97fd-1d87-4352-9da1-bbbf0a9419cf</uuid>
  <forward mode='nat'/>
  <bridge name='virbr0' stp='on' delay='0'/>
  <mac address='52:54:00:9a:e8:49'/>
  <ip address='192.168.122.1' netmask='255.255.255.0'>
    <dhcp>
      <range start='192.168.122.2' end='192.168.122.254'/>
    </dhcp>
  </ip>
  <ip family='ipv6' address='2001:b030:112f:ff5b:ffff:ffff:ffff:2' prefix='112'>
    <dhcp>
      <range start='2001:b030:112f:ff5b:ffff:ffff:ffff:1000'
end='2001:b030:112f:ff5b:ffff:ffff:ffff:2000'/>
    </dhcp>
  </ip>
</network>

When the host system is booted I get the following for virbr0

virbr0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.122.1  netmask 255.255.255.0  broadcast 192.168.122.255
        inet6 2001:b030:112f:ff5b:ffff:ffff:ffff:2  prefixlen 112  scopeid 0x0<global>
        inet6 fe80::5054:ff:fe9a:e849  prefixlen 64  scopeid 0x20<link>
        ether 52:54:00:9a:e8:49  txqueuelen 1000  (Ethernet)

But on the guest system I see only.

ens3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.122.75  netmask 255.255.255.0  broadcast 192.168.122.255
        inet6 fe80::e5c3:139f:1d2c:d126  prefixlen 64  scopeid 0x20<link>
        ether 52:54:00:e9:37:ee  txqueuelen 1000  (Ethernet)

Using wireshark on the host system I do see the following coming in

94    60.503493233    fe80::e5c3:139f:1d2c:d126    ff02::1:2    DHCPv6    147   
Solicit XID: 0x8265dd CID: 0004094110c9abc2d4b95bf6d1c6c0300065

But there is no response for the request.

Any ideas of what I may have missed?
