====== Virtualbox troubleshooting ======
===== Problem with assigning static ip to vm =====
Error:

<code>
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", "10.0.0.1", "--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
</code>

From virtualbox version 6.1.28 you need to whitelist the IPs from which the virtualbox can assign addresses. Create a file ///etc/vbox/networks.conf// with content:
<code>
  * 10.0.0.0/8 192.168.0.0/16
</code>
Note the asterisk at the beginning.
This will allow the above IP ranges to be assigned to the vms.


==== Tested on ====
  * Ubuntu 20.04.4 LTS
  * virtualbox     6.1.32-dfsg-1~ubuntu1.20.04.1


===== Date and time wrong (frozen) in VM? =====
Restart the timedate service. In Debian 11 do

  systemctl restart chronyd

Seems to be caused by the [[https://www.virtualbox.org/ticket/14605|absence of VBoxService]].

==== Tested on ====
  * Debian 11
  * vagrant install
