Cloud image specific bugs should be filed in the cloud-images project on Launchpad.net.

Cloud image

There are six images available, each for a different type of computer:

32-bit Cloud image
For almost all PCs. This includes most machines with Intel/AMD/etc type processors and almost all computers that run Microsoft Windows, as well as newer Apple Macintosh systems based on Intel processors.
64-bit Cloud image
Choose this to take full advantage of computers based on the AMD64 or EM64T architecture. Choose this if you are at all unsure. AMD64 is recommended for general computing use in the Cloud.
64-bit ARM Cloud image
For AARCH64/ARM64 based boards.
PowerPC64 Little-Endian Cloud image
For use on POWER8 Little-Endian capable hypervisors.
IBM System z Cloud image
For IBM System z series mainframes, such as IBM LinuxOne.
32-bit ARMHF Cloud image
For ARMv7 processors and above. Userland is compiled with Hard Float on.
