Doesn't work immediately, but AMT starts to work.

Is it normal?

When KVM sesion is open network card works only on 10baseT standard.
You cannot change speed:

  k8% # ifconfig em0 media 1000baseT &
  k8% # lo kernel -2
  May 25 01:01:14 k8 kernel: em0: Media change is blocked due to
SOL/IDER session.
  May 25 01:02:16 k8 kernel: em0: Media change is blocked due to
SOL/IDER session.

After closig KVM connection with VNC Viewer:

  k8% # ifconfig em0 media 1000baseT
  k8% ifconfig em0
  em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=4219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC,VLAN_HWTSO>
        inet 10.146.103.8 netmask 255.255.0.0 broadcast 10.146.255.255
        media: Ethernet 1000baseT (1000baseT <full-duplex>)
        status: active

And very important: after speed change AMT works fine.

Any kind of reset network card makes AMT good, for example:

ifconfig em0 -txcsum
