SetEnqueueReinitializeServer and vm.reinitialize() failure when ConfigureIPv6=True

[mz0]

tried both (via API and by posting to the respective URL), got error:
{"ExceptionInfo":null,"ResultCode":-500,"ResultMessage":"Object reference not set to an instance of an object.\u000d\u000aExceptionCode=-500\u000d\u000a","Success":false}

(Sure both my code snippets work when ConfigureIPv6=False)

fortunately a workaround exists:

• reinitilize (ConfigureIPv6=false)
• from GetServerDetails get ['Value']['NetworkAdapters'][0]['IPAddresses'][0]['StartRangeIPv6'] and ['Value']['NetworkAdapters'][0]['IPAddresses'][0]['PrefixIPv6'] (for Smart VM)
• add them to static IP configuration (the 7 lines below for Debian/Ubuntu) && reboot

append to /etc/network/interfaces:

iface eth0 inet6 static
pre-up modprobe ipv6
	address <StartRangeIPv6>
	netmask <PrefixIPv6>
	autoconf 0
	gateway fe80::1
	dns-nameservers 2001:4860:4860::8888
