Recently I reinstalled my build (DS3617xs/6.1.7) using a set of serial/mac(starting with 02:11:32) generated by Docker/DDSM. Everything went smooth until I create a new host in VMM, the mac of the DSM was changed to another random address(#1). I rebooted the DSM and kept looking at the router, the DSM started with 02:11:32 but later when the VM started, the DSM mac was changed again to another random address different from #1. I checked the grub.cfg of the usb drive and it wasn't changed. Now I am sure the DSM mac was changed during either the creation of a new VM or the startup of an existing one. Are there any methods to stop this?
