it's config VM (Centos 7) /etc/sysconfig/network-scripts/ifcfg-eth0
192.168.0.37 is your PVE host bridge interface IP, so inside your VM you have to set this as your gateway, and pick a different IP address for the VM
also probably it's better idea to pick a whole different subnet for this, like 10.0.0.0/24 so your VMs have their own internal subnet
