Comment 30 for bug 1847105

You may just help the user making an informed decision with all the pros and cons explained in the user interface. Such behavior, common to other virtualization solutions, was beautifully fulfilled before being removed with this commit: https://github.com/virt-manager/virt-manager/commit/15a6a7e2105440df528f75c4df4d2471df28bd1e#diff-03b5bf10a38d88f4a09a14e211c23e05. Every time I create a new virtual machine I need to use the command line to generate a dynamically allocated storage, which is not good.
