Additional Notes

• If VM is configured with BIOS to OVMF (UEFI) and is not able to boot while using i440fx as the Machine type, select q35 as the Machine type.

• In some cases the machine may not boot properly with CPU set to host. In this case it is recommended you set CPU to x86-64-v2-AES.

• Anything with a Linux Kernel of v3.16 or lower, requires the Display to use Standard VGA.

• Anything with a Linux Kernel of v3.16 or lower, may require to use the Default (LSI 53C895A) SCSI Controller type if it does not boot the disk using the recommended VirtIO SCSI single.
