Setup KVM on proxmox

We have a proxmox node and need someone to setup the bridge for KVM support. (paying $10 and great review with more work) LXC works great but when we create a container it works until we disbale network manager. We cannot get the KVM to connect to the internet once NETWORK MANAGER is disabled. Your job is to fix the bridge, so when KVM is setup it works after disabling network manager. Must know what you are doing because we have live VM with websites and cannot afford any downtime. Long term position is available because we always need someone to setup servers etc. Apply with confidence and i can only pay $10 since this is like a 10 mins job.
