Bug
Operating System Version
Flatcar latest main.
Ignition Version
2.24.0 because of Flatcar, but the root cause is outside Ignition, and the provider hasn't changed in years.
Environment
VirtualBox 7.2.8.
Expected Behavior
You can provide up to 128KB of user data on Linux, as documented by FCOS and noted in #1269.
Actual Behavior
VBoxManage returns a VERR_TOO_MUCH_DATA error when you set more than 1KB of data.
Reproduction Steps
Create a VirtualBox VM and try to set the guest property with more than 1KB of data.
$ ls -l config.ign
-rw-r--r-- 1 chewi users 1084 Apr 29 09:18 config.ign
$ VBoxManage guestproperty set 42e89654-5b5f-48a1-959b-616575bd2349 /Ignition/Config "$(< config.ign)"
VBoxManage: error: VERR_TOO_MUCH_DATA
VBoxManage: error: Details: code NS_ERROR_INVALID_ARG (0x80070057), component SessionMachine, interface IMachine, callee nsISupports
VBoxManage: error: Context: "SetGuestPropertyValue(Bstr(pszName).raw(), Bstr(pszValue).raw())" at line 151 of file VBoxManageGuestProp.cpp
Other Information
This is mostly a heads up, as there isn't much you can do beyond fixing the FCOS docs or maybe asking VirtualBox to increase the limit. Implementing gzip decompression will help a little but not much.
128KB was allowed at the time #1269 was implemented, but this changed to 128 bytes in VirtualBox/virtualbox@cffda6a and that was later raised to 1KB in VirtualBox/virtualbox@32a8ce0.
