Regardless dhcp-option 26,1454 is setup in system current image loads with MTU 1500
Workaround for now is to launch instance with no ssh keypair and having postinstallation script :

#cloud-config
password: mysecret
chpasswd: { expire: False }
ssh_pwauth: True

Then login to vnc-console with given password and run

# ifconfig eth0 mtu 1454 up

Setting stays stable between reboots. Details here http://bderzhavets.blogspot.com/2014/...
