[SRU][Q:linux-oracle][PATCH 1/1] UBUNTU: SAUCE: kvm: set `enable_virt_at_load` default to false

[Vinicius Peixoto]

From: Philip Cox <philip.cox at canonical.com>

BugLink: https://bugs.launchpad.net/bugs/2139360

Having nested virtualisation enabled breaks live migration on OCI.
Currently, KVM will enable it at the module load time, instead of upon
launching the first VM, and since it is autoloaded at boot time this
breaks live migration completely. Thus, tweak the default value of
enable_virt_at_load in order to make nested virtualization disabled by
default.
