create virtual system image and its file naming

so i managed to install ubuntu 14.04 64-bit with ext4 filesystem on a virtual system and i created an image from that virtual system.

when i look at how cloudmin name the image file, it always have .ext3.gz extension although i create the virtual system with ext4.

does cloudmin use the naming of the image file as how it decide which file system format it need to format for new virtual system? because if it does then the new virtual system that created using my ubuntu 14.04 image will have the wrong filesystem.

Closed (works as designed)

No, the image filename means nothing - it is perfectly fine for the actual filesystem to be in ext4 format, as long as the host system also supports ext4. When creating a VM from the image, the filesystem (ext4 in your case) will be preserved.
