Subject: KVM SVM(AMD) nested - disabled by default?
Date: Sat, 23 Jan 2016 16:07:21 +0100 [thread overview]
Message-ID: <56A39729.8020106@gmail.com> (raw)
"KVM: SVM: enable nested svm by default"
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/arch/x86/kvm?id=4b6e4dc
"Nested SVM is (in my experience) stable enough to be enabled by default. So omit the requirement to pass a module parameter."
I tried to get an explanation of the eventual -default- change here:
https://bugzilla.redhat.com/show_bug.cgi?id=1298244
but "... I am *thinking* of changing it ..." ain't explanation, man.
I've tested "Nested SVM" myself and it works surprisingly well,
therefore what is the -actual- reason to switch it off by default?
