Re: [Users] Nested virt failing

I have Fedora 18 with ovirt running. I have
vdsm-hook-nestedvt.noarch
installed on all the nodes.
The nodes are all identical with Intel i5-2400 CPUs (SandyBridge).
When I try to boot a nested virtual machine (L2) instead of a ovirt
virtual machine (L1), the kernel starts to load, and then that nested
virtual machines (L2) pauses.
On the host running Fedora 18 dmesg shows this message:
nested_vmx_run: VMCS MSR_{LOAD,STORE} unsupported
Reading this bug https://bugzilla.redhat.com/show_bug.cgi?id=892240
It looks like if the Fedora 18 ovirt nodes started the the L1 using
the "core2duo" CPU flag instead of host pass through it might work?
How do I do that, or are there other solutions?
Are you sure nested is enabled?
Check: cat /sys/module/kvm_intel/parameters/nested should say Y
Check your cluster for what cpu is used.
I have a test system where a core i3 isn't recognised as a sandy bridge
but a core i7 is. Have tried fiddling with libvirts xml file but no go.
