Description Rafael Martins 2016-07-26 15:10:46 UTC

Description of problem: when adding a new host, using ovirt-engine's Host -> New dialog, and enabling the "Nested Virtualization" option in the "Kernel" tab, host-deploy will generate a bad kernel command line parameter:

kvm-intel.nested=on

It is expected to be:

kvm-intel.nested=1

The wrong value results on kvm_intem module not loaded, and virtualization support disabled for the host.

Tested on CentOS 7 with kernel version: 3.10.0-327.22.2.el7.x86_64

Comment 2 Martin Polednik 2016-08-04 13:39:20 UTC

Could not really reproduce on RHEL, reproducible on centos. Same with unsafe interrupts.

Comment 4 Shira Maximov 2016-09-13 14:17:48 UTC

verified on :
Red Hat Virtualization Manager Version: 4.0.4.2-0.1.el7ev

verification steps: 
1.adding a new host: 
2. enabling the "Nested Virtualization" option in the "Kernel" tab
host-deploy generates the correct kernel command line parameter
kvm-intel.nested=1
