If the VirtualBox guest property /VirtualBox/GuestInfo/Net/1/V4/IP
returns an IP address ending in .1, raise an error.
This addresses an issue that was revealed as an NFS error, where Vagrant
was creating an exports file with the wrong IP address. This was thought
to be caused by the presence of a docker0 interface, but it manifested
itself even without Docker installed.
This issue is difficult to reproduce, but hopefully this PR will get us
closer to the root cause.
This commit creates a custom `read_dhcp_servers` method in the
VirtualBox 6.1 driver to handle changes made in the ouput of
`VBoxManage list dhcpservers`.
Tests for VirtualBox 6.1+ can no longer use the shared examples for the
VirtualBox 4.x driver, because the `read_dhcp_servers` change is not
backwards compatible.
This commit also creates the boilerplate for a VirtualBox 6.x shared
example in case we want to put tests there in the future.
This commit adds some recovery if Vagrant fails to reattach or clone a
vmdk disk that needs to be resized. It first moves the original disk
(after cloning) to a backup file. If something fails, it will reattach
the original disk to the guest and continue to raise the exception.
This commit catches the Errno::EPERM raised by the operating system if
the machine folder is inaccessible and displays it as a more friendly
error message.
This can be an issue on macOS Catalina if virtual machine files are kept
in a special directory (Documents/Downloads/Desktop) that Vagrant's
embedded Ruby is not allowed to access.
If VirtualBox is installed but the kernel module is missing or the
service is stopped, the usability test should fail without crashing so
we can fall back to other providers.

Prior to this commit, if a snapshot restore was run on an entire
environment with some non-existent guests, Vagrant would attempt to list
their snapshots with a nil id. This commit fixes that by returning an
empty list of snapshots if the machine has not been created yet.
In some cases the E1000 NIC type is the only acceptable value. Since
defaulting causes breakages to existing boxes, leave the default value
as `nil` but check the VirtualBox version in use and print warning to
user if VirtualBox version is vulnerable and E1000 NIC types are
configured for use within defined network adapters.
Be more restrictive when matching the port forward used for
SSH. Allow matching simply on the guest port, but also include
extra matching criteria for cases where multiple results may
be returned.
Display warning to user about the VirtualBox SharedFoldersEnableSymlinksCreate
option with link to VirtualBox documentation and instructions on how the
setting can be disabled.
Prior to this commit, the virtualbox synced folder option
`SharedFoldersEnableSymlinksCreate` was always enabled. This commit
introduces a config option and an environment variable which allows
users to configure the option globally or per synced_folder in their
Vagrantfile.
It should be valid to allow paths with spaces for the synced folder
guest path but since the guest path is used to generate the ID (if one
isn't provided), this will err out in VirtualBox because it doesn't
allow spaces for the --name argument. We should simply convert ' ' to
'_' as we do with other special characters.
When preparing the NFS settings on VirtualBox the guest IP addresses
are pulled from VirtualBox directly and any static addresses are
pulled as well. This can lead to aquiring a host IP and machine IP
but results in a failure of NFS mount because the IPs are not on
the same network. This filters the machine IP result to validate
it is within the host adapter IP range.
Set the IPv6 adapter IP to be <prefix>::1. Otherwise, guest to host
communication over IPv6 is not routed correctly. This means that
consumers should not specify <prefix>::1 IP addresses to VirtualBox,
which should be a reasonable restriction.
Fixes#6658
Vagrant should only consider the host-only interfaces used by the
virtual machine in the IPv6 fixup code. There may be other interfaces
present on the system with IPv6 addresses that for various reasons
would fail the routing check (for example, an interface with no
machines attached).
The patch changes the behavior to not scan all of the host-only
interfaces and adds a unit test for the behavior (that the correct IP
is validated).
Lastly, there is a small fix here that may not be an issue for most
people where the IPv6 prefix was asummed to be a multiple of 16 for
the purposes of constructing the UDP probe datagram. This assumption
has been removed.
Fixes#6586
