Problem running Dude in 7.22.1 CHR

Hello

This weekend due to have some time i tried to run Mikrotik in Virtual Machine. The aim is to run Dude inside ( as my old Dude machine is very old )

Attempt 1

Started Virtual machine in Qnap TS-251D: uploaded proper image, installed dude, imported database backup from old machine. Perfect run from the first shot !!!

Attempt 2

Installed Zimaos on some old machine. Stared Virtual Machine, uploaded proper image, installed dude.

To this point everything seems to work perfect.

Now problem occured. When importing backup database at first glance everything is correct. Import in theory OK. Proper files are built with Dude db at 37MB - just like in Attempt 1

BUT

When trying to run Dude I get: “applying settings: enabling: open db: not an error” and all device list, maps, everything is missing.

I do not know if it is important but virtual machine in Zimaos seems to be QEMU

Any idea how to fix ?

Regards

Peter
