Trying to run a couple of VMs using Vagrant. On running vagrant up command I get Call to virDomainCreateWithFlags failed: internal error

Question

Trying to run a CentOS 7 VM on Virtual Box using vagrant on my Fedora 35 machine. On running the run the vagrant up & vagrant up --debug commands I get the following message as output.

There was an error talking to Libvirt. The error message is shown
below:

Call to virDomainCreateWithFlags failed: internal error: /usr/libexec/qemu-bridge-helper --use-vnet --br=virbr0 --fd=27: failed to communicate with bridge helper: Transport endpoint is not connected
stderr=failed to get mtu of bridge `virbr0': No such device

Answer 1

So I was making a rookie mistake of not properly defining the VM provider in vagrant up command. Running vagrant up --provider virtualbox fixed this issue.
