VBoxmanage error when creating network devices

[Celeris113]

When creating the VM, I get the following error:
==> server2: Clearing any previously set network interfaces...
There was an error while executing VBoxManage, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["hostonlyif", "ipconfig", "vboxnet0", "--ip", "192.168.55.1", "--netmask", "255.255.255.0"]

Stderr: VBoxManage: error: Code E_ACCESSDENIED (0x80070005) - Access denied (extended info not available)
VBoxManage: error: Context: "EnableStaticIPConfig(Bstr(pszIp).raw(), Bstr(pszNetmask).raw())" at line 242 of file VBoxManageHostonly.cpp

This seems like a issue with the latest Virtualbox versions (I'm on 6.1.32).

I also am having this issue

The solution is very simple. You have to edit the /etc/vbox/networks.conf file(if it is not exsist you have to create) and add the following line:

* 192.168.55.0/24

After that, try vagrant up again.

On Linux, macOS and Solaris Oracle VM VirtualBox will only allow IP addresses in 192.168.56.0/21 range to be assigned to host-only adapters. For IPv6 only link-local addresses are allowed. If other ranges are desired, they can be enabled by creating /etc/vbox/networks.conf and specifying allowed ranges there. For example, to allow 10.0.0.0/8 and 192.168.0.0/16 IPv4 ranges as well as 2001::/64 range put the following lines into /etc/vbox/networks.conf:

  * 10.0.0.0/8 192.168.0.0/16
  * 2001::/64
