Doc Text:	Previously, an issue with imprecise kvm detection caused the TUI to fail to recognise when Intel/AMD virtualization support had been turned off in the BIOS. This has been fixed so that now both the TUI and the login screen show an error message if virtualization support is turned off.	Story Points:	---

Description cshao 2012-11-08 03:31:11 UTC

Description of problem:
"Virtualization hardware was detected but is disabled" miss in TUI when disable Intel/AMD virtuallization support in BIOS.

Version-Release number of selected component (if applicable):
rhev-hypervisor6-6.4-20121031.0.el6


Steps to Reproduce:
1. Disable Intel/AMD virtuallization support in BIOS.
2. Install RHEVH and reboot.
3. Login RHEV-H and focus on TUI.

Actual results:
1. "Virtualization hardware was detected but is disabled" can show in login screen, but miss in TUI.

Expected results:
"Virtualization hardware was detected but is disabled" can show in TUI and login screen.

Additional info:
No such issue in 6.2 & 6.3 GA version, so it is a regression bug.

The kvm detection wasn't precise enough.

Comment 5 Fabian Deutsch 2012-11-21 12:30:54 UTC

Tested as follows:

1. Install RHEVH with patch in VM (without nesting)
2. Boot RHEV-H
3. Focus on login prompt: Virt. hardware was not detected is on the screen
4. Login and focus on lower half: Virt hardware was not detected is on the screen

Test version:
rhev-hypervisor6-6.4-20121206.0.el6

"Virtualization hardware was detected but is disabled" can show in TUI and login screen when disable Intel/AMD virtualization support in BIOS.
So the bug is fixed, change bug status to VERIFIED.

Re-test with version rhev-hypervisor6-6.4-20121212.1.el6,

"Virtualization hardware was detected but is disabled" can show in TUI and login screen when disable Intel/AMD virtualization support in BIOS.
So the bug was fixed.
