By the way, I have asked the same question on VirtualBox support forum and attached my VM logs.
That is link
and there is a comment:
After some more comparative analysis (not between your two VMs), here are some interesting things that I found:
00:00:01.858220 Guest OS type: 'Other_64'
00:00:01.860906 File system of 'E:\VMs\bitnami-redis-4.0.6-0-r04-linux-debian-9-x86_64-disk1.vmdk' is ntfs
That's a really weird template choice for a Debian. I mean, the "Debian (64 bit)" option is right there...
00:00:02.054505 RamSize = 0x0000000020000000 (536 870 912, 512 MB)
That's rather small for a 64-bit Debian. Most probably because of the wrong template? Not really, because the default for "Other 64" is 64 MB, not 512. So somebody messed with, just not enough...
Speaking of messing (up). LSILogic? Why, oh, why? Because it can?
I think you should talk to the Bitnami people...
