[Interest] Detemine Run into VM

[Jérôme Godbout]

Ok, cool, I was more looking for Linux in fact, the Windows VM doesn’t show the problems with cdc_acm (I have tons of other problems with Windows 7 and cdc_acm, but this one issue is only under Linux when it run inside a VM Virtual Box).

For VMWare, I wrote this up a while ago:

Maybe something similar could be used for VirtualBox?

Is there a way to detect the application run inside a VM from Qt? I have a different behavior on how I need to handle a cdc_acm under VirtualBox (and possibly VMWare, but I haven’t tested yet). I was looking at QSysInfo, but I’m nont sure I will be able to confirm this with it.

Else I can run a bash command:
grep -q ^flags.*\ hypervisor /proc/cpuinfo && echo "This machine is a VM"

But I’m looking at a more clean way to detect I run inside VirtualBox. Any idea?
