Intel Virtualization enabled

I have intel virtualization enabled and my CPU supports it. However, when I run the installer no error pops up. However I thought I’d check if virtualization truly is working by putting in the following command in qubes:

egrep ‘^flags.*(vmx|svm)’ /proc/cpuinfo

However nothing comes up which indicates it’s not actually supporterd despite not having any errors during install.

My CPU is:
Intel® Core™ i7-2655LE

Which has:

Intel® Hyper-Threading Technology ‡ Yes
Intel® Virtualization Technology (VT-x) ‡ Yes
Intel® Virtualization Technology for Directed I/O (VT-d) ‡ Yes
Intel® VT-x with Extended Page Tables (EPT) ‡ Yes

Why is this? Like I said installed without any pop up errors which I’ve seen others get.

Linux dom0 kernel doesn’t see ‘vmx’ or ‘svm’ CPU flags in “/proc/cpuinfo” because Xen hypervisor is using the hardware virtualization features and hiding the flags from dom0, Xen dom0 is actually a virtual machine, so it doesn’t see all the cpu flags as Xen hypervisor is hiding some flags from dom0.

You can dmesg and inspect if VMX is enabled or not.
xl dmesg | grep -i vmx
