[Impact]
Using nested KVM on some hypervisors doesn't work.
[Test Case]
1) enable nested KVM:
sudo modprobe -r kvm_intel
sudo modprobe kvm_intel nested=1
cat /sys/module/kvm_intel/parameters/nested
# should say Y
2) generate an L1 guest and then generate an L2 guest inside the L1 guest
- ensure L1 has enough memory to boot L2
- if using libvirt you may need to edit the default bridge to use a different subnet than the L1 guest
3) boot the L2 guest
4) L2 guest should boot
If not you can see the log:
sudo cat /var/log/libvirt/qemu/nested-L2.log

Using nested KVM on some hypervisors doesn't work.
[Test Case]
A script to make this easier is posted here:
https://gist.github.com/arges/9d21c6da03a8c10d3980
1) enable nested KVM:
sudo modprobe -r kvm_intel
sudo modprobe kvm_intel nested=1
cat /sys/module/kvm_intel/parameters/nested
# should say Y
2) generate an L1 guest and then generate an L2 guest inside the L1 guest
- ensure L1 has enough memory to boot L2
- if using libvirt you may need to edit the default bridge to use a different subnet than the L1 guest
3) boot the L2 guest
4) L2 guest should boot
If not you can see the log:
sudo cat /var/log/libvirt/qemu/nested-L2.log

[Impact]
Using nested KVM on some hypervisors doesn't work.
[Test Case]
A script to make this easier is posted here:
https://gist.github.com/arges/9d21c6da03a8c10d3980
1) enable nested KVM:
sudo modprobe -r kvm_intel
sudo modprobe kvm_intel nested=1
cat /sys/module/kvm_intel/parameters/nested
# should say Y
2) generate an L1 guest and then generate an L2 guest inside the L1 guest
- ensure L1 has enough memory to boot L2
- if using libvirt you may need to edit the default bridge to use a different subnet than the L1 guest
3) boot the L2 guest
4) L2 guest should boot
[Fix]
These three upstream patches needed to be backported to 3.13:
* 533558bcb69ef28aff81b6ae9acda8943575319f
- This provides necessary code changes to make backporting easier. However vmx_leave_nested function was not yet added, so that function modification was dropped.
* b6b8a1451fc40412c57d10c94b62e22acab28f94
- This patch is necessary in order to ensure that the L1 guest doesn't crash with just 696dfd95 applied. I had to remove mpx mentions from the cherry-pick as that feature hasn't been added yet.
* 696dfd95ba9838327a7013e5988ff3ba60dcc8c8
- This patch fixes the issue and was the result of the bisection. The APIC virtualization features need to be disabled as they cause L2 guests to not boot depending on the CPU.

If the L2 guest doesn't boot you can see the log:
sudo cat /var/log/libvirt/qemu/nested-L2.log
