Virtualbox 6.1.40 and Peropesis 1.8 64bit ISO
I had some problems loading 1.8 in Virtualbox.
What I did was to create under storage , IDE controller
add Peropesis 1.8 64bit ISO as an optical drive.
Also, in the manual
under 2.4 live hosting by using virtual machine
2.5 starts with "now you can to try to load"
should read "2.5 now you can try to load".
A quick note. To shutdown quickly type "telinit 0".
