If i try to change the ip address or subnetmask of my host only network, i receive the following error code:
Failed to save host network interface parameter.
Callee RC:
E_ACCESSDENIED (0x80070005)
Does anyone know how to fix it? I have a linux system based on arch

Re: Error: Host Only Network- Failed to save host network interface parameter - E_ACCESSDENIED
A new setup for Linux Hosts was introduced in 6.1.28. See https://www.virtualbox.org/manual/ch06. ... k_hostonly
On Linux, Mac OS X and Solaris Oracle VM VirtualBox will only allow IP addresses in 192.68.56.0/21 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
Lines starting with the hash # are ignored. Next example allows any addresses, effectively disabling range control:
* 0.0.0.0/0 ::/0
If the file exists, but no ranges are specified in it, no addresses will be assigned to host-only adapters. The following example effectively disables all ranges:
# No addresses are allowed for host-only adapters

What was the underlying reason for this change? It seems very arbitrary to only allow 192.168.56.0/21 by default for host only networks.
Edit: How would additional networks be enabled on Mac OS VirtualBox? What is the Mac equivalent of /etc/vbox/networks.conf ?

The old method had a permissions security hole on non-Windows hosts. The networks.conf file requires admin privileges to change, which plugs the security hole.virtualvertigo wrote:What was the underlying reason for this change?
