I was affected by this bug, too - I use nested virtualization a lot, mainly for system testing purposes. I was able to reproduce the issue on all 3.13 kernels so far; my hardware is a Intel Core i7-2640M. Kernel release 3.13.6 fixed the issue for me. Looking at the changelog at https://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.13.6, I guess the fix was in commit 92cb6f3c5533832aa70a7dc9326ef21270169583 " kvm, vmx: Really fix lazy FPU on nested guest". The issue is discussed on the kvm-devel mailing list: http://thread.gmane.org/gmane.comp.emulators.kvm.devel/119328 leading to the fix: http://permalink.gmane.org/gmane.linux.kernel.stable/82043. -- You are receiving this mail because: You are watching the assignee of the bug.
