Hi,
I was trying to test patches for vmm and uvm by Stefan Kempf. Everything
works great and copies between the host and guest are faster with the
patches but I noticed the following.
Whenever I reboot the VMM host (running OpenBSD 5.9 -current from yesterday
with custom kernel enabled with vmm0 at mainbus0) the guest OS (OpenBSD 5.9
-release) has a different MAC address for the same vio0 interface.
Is this expected behavior? Reason for asking this is that if it is not
expected behavior then probably I may be doing all this incorrectly and any
feedback from my tests would just be a time waste for developers. So wanted
to avoid that if possible.
I am running dhcpd on the host and the lease file looks as follows. I only
have one VM guest on this test system.
