more oracle virtual box bugs here
the ultimate desktop gnu/linux, apple osx and ms windows 10 all running at once thanks to the power of oracle virtualbox
virtualbox tips of the week check bios vt and dont overcommit ram
do this
not this
WATCHOUT Oracle VirtualBox nat networking is not the same as VMware nat networking
VirtualBox 5.x default “built in” “hardcoded” NAT networking gives every VM the same IP 10.0.2.15 which will not let VMs talk to each other and VMs will also NOT work if you netadmin or sysadmin is using the 10.0.2.x subnet on your network
Apparently
This separation maximizes security since by default virtual machines cannot talk to each other.
The documentation and network naming could be clearer BUT note in virtualbox if you want VMs to be able to talk to each other you must create your own “NAT Network” instead of using “NAT” network before creating VMs and assigning networks to them
ubuntu xubuntu 14.04.02 64bit @oracle @virtualbox 5.0.8 64bit on @intel T2390 only allows me to create 32bit vms ! why ?
