I don't know where to write, but there is a problem in TOS 7 when installing virtual machines.
I have TerraMaster F4-425 Plus. I installed TOS 7 7.0.0227. Everything works fine until I install the virtual machine. As soon as I install this package or activate OVS in the network settings, everything will work as it should. But as soon as I reboot the server, it disappears from the network. In HDMI, an error appears on the monitor during boot and the OS boots without network cards.
This is a huge problem for me, because I installed TOS 7 only because of virtual machines. Please fix this problem or tell me how to fix it yourself.

I found another problem in VMM. In the Safari browser, an error hangs red on the virtual machine screen. If you take any other browser, there is no such problem.

Re: TOS 7 Insider Preview Program
Thank you for your feedback. I will forward this issue to the product team to test Safari browser compatibility.

I'm updating everything. It was disabled on TOS 6 and continues to be disabled when updating to TOS 7.

I was just going to quote the OP,
"As an early-stage version, TOS 7 Insider Preview may contain bugs or incomplete features.To avoid causing inconvenience to others, please do not publicly share any issues or version details encountered during testing."
and ask you to reconsider my application (which I sent in accordance to the rules but never even got a response to)...
