Linux Mint 19.1 Cinnamon Release Notes - Linux Mint |
These release notes are actually *helpful*. Covers the issue I had with garbled display on VirtualBox *and* being able to move around windows that are too large (like Timeshift's setup wizard) to fit on the screen at the default screen resolution.

The problem I had with the system menu not showing up on the first reboot after setup went away after resetting the menus (or a reboot).
If the screen is garbled when launching Linux Mint in Virtualbox, switch to console with HOST+F1 (e.g. the RIGHT Ctrl key, no ALT) and back to tty7 with HOST+F7.

Another workaround is to disable "nested paging" (in the System -> Acceleration settings) and to increase the video memory to 128MB (in the Display settings).

Note: This issue only affects the live session. You don't need these workarounds post-installation.

Wonky display on this one Win10 startup screen in VirtualBox - Linux Mint Forums |
I asked a question a few days ago about a video snow display when booting LM19 Live DVD in Virtual Box. Turns out that you need to use R-CTRL / F2 followed by R-CTRL / F7 [Host-F2, Host-F7] to go in and out of a terminal to clear the snow. Have you tried this to fix your Wonk? Maybe the Linux Graphics Drive is not really up to snuff with the Virtual Machine Host graphics. After installing the LM 19 system in the VM I have not seen snow again. Or any Wonk. Or at least now your kind of Wonk.

Lots of good suggestions here, but all that was *really* necessary was to bridge the physical adapter ('eno1' for me) and install the non-free Extension Pack.

networking - PXE boot with Virtualbox - Server Fault
The PXEboot server that VirtualBox's (default) NAT network interface communicates with is built-in, that's why the filename it looks for matches the name of the VM.

I set up a bridged adapter (br0) using the instructions here ( and told the VirtualBox VM to use that instead. Then everything worked fine.
After clarification, not using VirtualBox's built-in PXE feature at all seems the way to go. Instead, assign a secondary NIC with "host only" or "internal" networking to server and client, and bind the DHCP server to listen at the second interface. Do not use Intel cards for the second interface: PXE Booting Virtualbox guests in internal networking mode?

Answer to VirtualBox NAT and PXE:

Basic Usage - Synced Folders - Vagrant by HashiCorp
Modifying the Owner/Group

By default, Vagrant mounts the synced folders with the owner/group set to the SSH user. Sometimes it is preferable to mount folders with a different owner and group. It is possible to set these options:

config.vm.synced_folder "src/", "/srv/website",
owner: "root", group: "root"

Mount options for mount.vboxsf:

set the default file owner user id to UID

set the default file owner group id to GID

set the "time to live" to TID for the dentry

override the mode of all directories to (octal) MODE

override the mode of all regular files to (octal) MODE

set the umask to (octal) UMASK

set the umask applied to directories only

"Vagrant could not detect VirtualBox!" · Issue #192 · ptwobrussell/Mining-the-Social-Web-2nd-Edition · GitHub
Ran into this once during a workshop; solution was to add the path where the user had installed VirtualBox (it was something odd, like C:\Program Files\Oracle) to the PATH environment variable. Possibly the registry was out of sync with the actually VirtualBox installation path, or maybe Vagrant is hard-coded to look for VBoxManage.exe in only a couple of places on Windows.

Same problem I had, either after OS or VirtualBox upgrade (-> 5.0.something): no idea what the actual problem was, but creating a new Windows VM and then selecting the .vdi from the "broken" one solved the problem.

Most of the troubleshooting "advice" on the VirtualBox forums for this error is *way* off, maybe because people aren't paying attention to which *component* is implicated;
The VM session was aborted.

#6877 (Broken if cancel creation snapshot => fixed in SVN) – Oracle VM VirtualBox
Referred here by another article: "NS_ERROR_FAILURE (0x80004005)"

Solution was to remove the fixed disk from the storage manager and then re-add it to the VM. No idea.

In the GUI, remove the existing guest VM,
Create a new guest VM (click the New button),
Use the wizard to set up the new VM (be careful, you should probably select Use existing image VMDK if VBox was accessing the guest via VMDK / raw partition),
Change the Settings (it can be found under the Machine menu) per your requirements,
Quit VBox,
Restart VBox,
Run the guest VM.

VirtualBox – Cannot Register the Hard Drive Because a Hard Drive with UUID Already Exists – Bradley Schacht
I looked all over the place to find what was causing it and finally found a fix. Of course it requires the command prompt, so open that junk up and let’s get started!

**Note that I am on VirtualBox version 4.1.6 and from what I’ve read this command used to be something different a few versions ago. I think instead of setdhuuid it was setvdiuuid, but don’t hold me to that.**

Open the Command Prompt
Change the directory to where VirtualBox is installed (Default: C:Program FilesOracleVirtualBox)
Type the following VBOXMANAGE.EXE internalcommands sethduuid <PathOfNewVHD>

Note that internalcommands and sethduuid need to be lowercase. I spent more than a couple minutes trying to figure out why things weren’t working.

GitHub - jedi4ever/veewee: Easing the building of vagrant boxes
The first step to build a new virtual machine is to download an existing 'base box'. I believe this scares a lot of people as they don't know how these unverified boxes were built. Therefore a lot of people end up building their own base box which is often time consuming and cumbersome. Veewee aims to automate all the steps for building base boxes and to collect best practices in a transparent way.

The "If No" (not used by multiple machines) worked for me. So far. Fingers crossed.
Re: Discard Snapshot /w 2 HDD? For backup?

Postby MarkCranness » 27. Oct 2009, 02:44
The '...has more than one child hard disk (n).' message likely occurs because the VDI is being used by more than one VM (currently, or was/is used by another VM's snasphot).

To see which VMs may or may not have the VDI attached, use File>Virtual Media Manager, select the VDI file and expand the tree below it (use * on the numeric keypad).

Is the VDI currently being used by multiple VMs?

If No, then you should be able to Remove some of the child {hexUUID} VDI files immediately under the main VDI in the tree, until there is only one child {hexUUID} VDI left and then the snapshot can be discarded.
Select each child {hexUUID} file in turn and note what it says below 'Attached to:'.
If it says 'Not Attached', then that file can be Removed.

If Yes, then you will have to decide which VMs will have their Current State (as relates to that base VDI) discarded and which VM will have it's Current State preserved (if any).
(This is because the snapshot you are trying to discard is snapshotting/protecting the base hard disk and it needs to be protected if it is to be shared by multiple VMs.)

For all VMs that will have their Current State discarded (as relates to that base VDI), do the following:
In Virtual Media Manager, find the immediate child {hexUUID} file that is attached to the VM
Does that file have its own '+' sign and a tree under it?
If Yes, then view the VM's snapshots, and Discard the last (current, bolded) snapshot, (preceeded by a Revert if appropriate...) and repeat until the child does not have a tree
Select the (treeless) immediate child and use 'Release' followed by 'Remove' to delete that file (this does a 'Revert' on the Current State, as it relates to this base VDI)
In the VM that will have it's Current State preserved, you should now be able to Discard snapshots as normal.

Backup/whatever you need to do with the base VDI, take a snapshot on the main VM and then reattach to the VMs that were 'Released' above.

Howto: SSH into VirtualBox 3 Linux Guests by Stuart Colville
This method works all right (creating a host-only network in the VirtualBox application's preferences, then creating a host-only adapter for the VM), but setting up port forwarding with the primary NAT-only interface works okay, too. You just need to follow the advice here ( and do NOT specify an IP address for either the host or guest.

Then connecting to localhost -p <whatever> works just fine, whereas specifying for the guest IP (as you'd expect) gives you a "connection refused" or similar error.

january 2014 by kme • View topic - How to ssh into a guest using NAT?
Aha. Maybe there's another way to do this, but in VirtualBox, VM's Network panel, click on advanced, click on Port Forwarding button. In there set up a rule:

Host IP:
Host Port: 2222
Guest IP:
Guest Port: 22

Then enable ssh in the guest, and I'm able to connect from the host using:

ssh -p 2222 root@

I haven't tried it because I don't have a 2nd computer, but I think ssh -p 2222 root@ would also work.

I can't seem to use "" as the guest IP, which would make the most sense. I guess this works fine as long as VirtualBox assigns the same IP to each guest, no matter how many VMs you have running.

However, following the advice here (, and LEAVING THE HOST AND GUEST IP addresses BLANK, you can SSH with 'ssh -p <whatever_port> localhost' just fine.

Alternatives using a host-only network and setting up a second, host-only network adapter for the VM also work, but unnecessarily complicate things, and make sharing the VM image with others more of a challenge (because they also have to set up the host-only network, and the network address/subnet mask must match the configuration on the VM).

After a late-November 2013 Windows Update frenzy, the Win 7 VM had a corrupted disk and was stuck in an update/rollback/reboot/fdisk/reboot cycle. These instructions seemed legit, but probably 'CHKDSK /f' (or /r) and a System Restore rollback will be what ends up fixing it. Or recovering to a VM snapshot
Run the sfc /scannow System File Checker command to replace a missing or corrupt copy of the user32.dll file. If this DLL file is provided my Microsoft, the System File Checker tool should restore it.

But what I actually ended up doing was this: (NT-style). But then what I actually ended up doing was actually rolling back to a previous VM snapshot.
