[pve-devel] [PATCH pve-container] Convert to disksize to GB after reading the config file

This fixes a bug when calling pct restore a vzdump backup:
we store the rootfs size in KB, but create_disks expects that a GB parameter.
So the restore was failing trying to create something of a Petabyte image.

Formatting '/var/lib/vz/images/110/vm-110-disk-1.raw', fmt=raw size=4503599627370496
unable to create image: qemu-img: /var/lib/vz/images/110/vm-110-disk-1.raw: The image size is too large for file format 'raw'
