Hi, I installed Qubes OS R4.0-rc3 on my HP laptop with disk table GPT with
UEFI. I installed Qubes root on encrypted partition and EFI on unencrypted
partition 200 MiB. All install was without problems. But when I run system
I saw this error (attachment 1[20171128_154733]), I click "OK" and I tried
run system. It run but sys-net,sys-usb,sys-firewall don't want start when
I try run it. I open terminal for you and show logs (attachment
1[img_20171128_162924.jpg] -> 2[img_20171128_162949.jpg] ->
3[img_20171128_163006.jpg]). In my opinion it is bug in system.

When I tried create new VM based on Fedora I saw something strange because
it don't want run even if I created VM based on Debian. And when I open
terminal and for test run this commands I see this.

I had this issue installing 4-RC2, not sure what it is due. First, check that your system is capable of VT-d and VT-x. If both your CPU and your chipset supports it, make sure it is enabled in the bios. Check `sudo xl dmesg | grep VT` for hints. If VT-x and VT-d are enabled and you still get this error, try this workaround:

- Make sure it's a fresh install (revert your progress so far)
- When you are greeted with the setup after install, hit Ctrl-Alt-F3 to go to the console. If you got a black screen, try a few times Alt-F1 and Alt-F3 until you can loging
- Start the following bash loop (what's inside the back ticks) ` while true; do qvm-ls | grep -v NAME | awk '{print $1}' | xargs -I{} sudo qvm-prefs {} virt_mode pv; sleep 0.5; done`. This will continuously change the virt_mode to PV for all VMs
- Switch back to the setup with Alt-F2
- Continue setup, but do not login or reboot
- Switch back to Ctrl-Alt-F3
- Kill the loop and run `sudo qubes-dom0-update --enablerepo=qubes-dom0-current-testing`
- Switch all VMs back to HVM: `qvm-ls | grep -v NAME | awk '{print $1}' | xargs -I{} sudo qvm-prefs {} virt_mode hvm`
- Reboot

Can I do this if my CPU support only VT-x without VT-d ? What I should do ?
