Packer fails to build Virtualbox VM using WSL2 and Hyper-V (Host: Windows 10 2004, WSL: Ubunto 20.04)
e.g.
virtualbox-iso output will be in this color.
==> virtualbox-iso: Retrieving Guest additions
virtualbox-iso: Using file in-place: file://./C:%5CProgram%20Files%5COracle%5CVirtualBox/VBoxGuestAdditions.iso
==> virtualbox-iso: Retrieving ISO

Build 'virtualbox-iso' errored: Error starting VM: VBoxManage error: VBoxManage.exe: error: VMMR0_DO_NEM_INIT_VM failed: VERR_NEM_MISSING_KERNEL_API_2 (VERR_NEM_MISSING_KERNEL_API_2).
VBoxManage.exe: error: VT-x is not available (VERR_VMX_NO_VMX)
VBoxManage.exe: error: Details: code E_FAIL (0x80004005), component ConsoleWrap, interface IConsole
==> Some builds didn't complete successfully and had errors:
--> virtualbox-iso: Error starting VM: VBoxManage error: VBoxManage.exe: error: VMMR0_DO_NEM_INIT_VM failed: VERR_NEM_MISSING_KERNEL_API_2 (VERR_NEM_MISSING_KERNEL_API_2).
VBoxManage.exe: error: VT-x is not available (VERR_VMX_NO_VMX)
VBoxManage.exe: error: Details: code E_FAIL (0x80004005), component ConsoleWrap, interface IConsole
The reason it fails is because HyperV is enabled and thus VT-x is not available.
If I build this manually, I can create the Virtualbox VM (not using Hyper-V), then using ‘vboxmanage modifyvm’ I can change the ‘paravirtprovider’ to ‘hyperv’. However, using Packer this does not seem possible as the build fails because Packer tries to create a virtualbox-iso using the default (i.e. virtualbox, not hyperv), which of course will fail (as noted above).
There is the option to set ‘vboxmanage’ or ‘vboxmanage_post’ e.g. ‘“vboxmanage_post”: [ [“modifyvm”, “{{ user template }}”, “–paravirtprovider”, “hyperv”] ]’, but this fails as above, i.e. cannot create the initial VM.
Any ideas for a workaround?
Below is the cmd
e.g.
packer build -force -only=virtualbox-iso ubuntu-2004-server-amd64.json
And below is the Packer script e.g. ‘ubuntu-2004-server-amd64.json’ (based on Bento scripts).
