vagrant up stops with an error

[witchi]

I try to start the OracleDatabase 19.3.0 with vagrant up but it results always in an error and the gust instance doesn't run:

Mounting NFS shared folders... (stops here for long time)

The following ssh command responded with a non-zero exit status.
Vagrant assumes that this means the command failed.

mount -o vers=3 192.168.121.1:/opt/install/vagrant-projects/OracleDatabase/19.3.0 /vagrant
mount.nfs: Connection refused

I have set some firewall rules to open ports for NFS, but there are no differences:

firewall-cmd --list-all
service: mountd nfs rpc-bind ssh ldap ldaps http https dhcpv6-client

Environment

• Vagrant provider:
  • For libvirt:
    • Vagrant-libvirt plugin version: 0.7.0
    • Vagrant-env: 0.0.3
    • QEMU version: qemu-kvm-6.2.0-150400.37.8.2.x86_64
    • libvirt version: libvirt-8.0.0-140400.5.8.x86_64

Seems to work with

$ sudo firewall-cmd --permanent --zone=libvirt --add-service=nfs3 \
    && sudo firewall-cmd --permanent --zone=libvirt --add-service=nfs \
    && sudo firewall-cmd --permanent --zone=libvirt --add-service=rpc-bind \
    && sudo firewall-cmd --permanent --zone=libvirt --add-service=mountd \
    && sudo firewall-cmd --reload

(found on https://developer.fedoraproject.org/tools/vagrant/vagrant-nfs.html)

I have to allow the NFS ports on the firewall zone, which is used by the interface virbr1 (created by libvirt). On OpenSuse Leap 15.4 the zone is called libvirt.

Indeed, it is the same for OL8, the libvirt bridge has its own zone - see https://blogs.oracle.com/linux/post/getting-started-with-the-vagrant-libvirt-provider-for-oracle-linux
