Resize of manually created VM (macOS)

[dockay]

First, thanks for the great tool!

We are using it with manually creating VMs with tart create --from-ipsw=latest ventura-vanilla --disk-size 60

Now we ran into the issue, that the disk size we specified is not enough. Is there any way to extend the existing VM disk-size? Instead of re-creating everything from scratch with a bigger disk-size.

I found this related comment: #17 (comment), but I would love to be able to have tart to automate this process if possible, too.

This does not work, if you have a recovery-partition installed. As we do have. I can't remove it, as I need to boot into recovery-mode, but there is no way to boot into it via command line anymore on ventura.

We now found a solution for our problem.

First there is a --recovery option for tart run. So you can run into recovery mode via tart run vmname --recovery.

On the host you then can use truncate to resize the disk.img to desired size.

Then start the vm with above command tart run vmname --recovery.

We had the issue, that we had an additional recovery partition between our free space and our container.

In recovery mode, disable csrutil csrutil disable.

diskutil list to find the Apple_APFS_recovery partition.

diskutil apfs deletecontainer diskxx

diskutil repairdisk disk2

You should now have the free space to your demand.

Find your apfs container you want to grow.

diskutil apfs resizecontainer diskxx 0

reenable csr.

csrutil enable

and reboot without --recovery.

When executing the following command:
diskutil apfs deletecontainer diskxx (Apple_APFS_recovery partition)
it results in the deletion of disk2, which makes diskutil repairdisk disk2 impossible. What should I do?

i use :

tart clone ghcr.io/cirruslabs/macos-monterey-xcode:13.4 monterey
tart set monterey --disk-size 150
tart run monterey

Alternatively, one can use Tart Packer Plugin to automate image creation. The plugin removes a recovery partition by default and can resize disks too. Here is a repository with our example templates.
