Synology DS3617XS Virtual Machine - sometimes hangs on boot

[Mostlydangerous]

Good Afternoon,

I have been running OPNSense as a virtual machine on a Synology DS3617XS for more than 12 weeks.

Mostly everything works as expected.

However occasionally the virtual machine hangs during the booting process.

It looks to be searching for a FD controller and sits there timing out whilst it looks.

If I log onto the console on the Synology virtual machine manager and connect to the console, with a few forced reboots of virtual machine it will start as expected.

When OPNSense has been running I have added the QEMU plug in.

Has anyone else experienced similar issues at all?

The Synology has a Xenon and 48GB RAM.

Currently on the Synology:
DSM is: DSM 6.2.4-25556 Update 2
Virtual Machine Manager is: 2.5.3-9760

Thank you
