When trying to run IE11 in Virtualbox (Ubuntu 14.04 host) I get the following:
ERROR: VT-x/AMD-V hardware acceleration is not available on your system. Certain guests (e.g. OS/2 and QNX) require this feature and will fail to boot without it.
doing some research I found out that in order to enable VT-x/AMD-V I need to make sure that:
1. The CPU you're using actually supports hardware virtualization.
2. Hardware virtualization is enabled in your bios.
3. Lastly that it's enabled in your vbox configuration.
I believe that my hardware supports virtualization since I see 'svm' in color when running this command: grep --color vmx /proc/cpuinfo
(based on How do I enable hardware virtualization technology (VT-x) for use in Virtualbox?).
in order to meet #3 i need to enable it in vbox but the Acceleration tab in my vbox is disabled.
I did some searching and found this thread: https://bbs.archlinux.org/viewtopic.php?pid=1356653
It suggested the following: vboxmanage modifyvm IE11 --longmode off
I did that but it didn't solve my issue.
Here is the IE11 that I use (i took it from modern.ie/en-us/virtualization-tools)
