HELP!!!

I have Unraid 6.12.11 and I have enabled vlans - I can access to the unraid gui on both default (192.168.0.101) and vlan 6 )192.168.24.101) networks.

However when I try to start a VM after changing the network source to br0.6 I get the error "internal error: process exited while connecting to monitor"

I reverted all the changes so I am now back on thre default network and although I can get access to thr unraid webgui I cannot start the vm. Again i get the message "internal error: process exited while connecting to monitor"

Here is the vm logs.....

I eventually rebooted the server and the problem resolved itself.
