description |
A guest will hang while booting under 4.18.0-10.11 because of "kvm: x86: Set highest physical address bits in non-present/reserved SPTEs", which came in via 4.18.y.
A fix is already upstream, and already present in 4.18.14.
This would be upstream commit
daa07cbc9ae3da2d61b7ce900c0b9107d134f2c1 ("KVM: x86: fix L1TF's MMIO GFN calculation"). |
[Impact]
A guest will hang while booting under 4.18.0-10.11 because of "kvm: x86: Set highest physical address bits in non-present/reserved SPTEs", which came in via 4.18.y.
[Test Case]
A guest was booted after applying the patch.
[Regression Potential]
It might break KVM on systems with different physical memory limits, which is just what upstream might have been testing the most.
============
A fix is already upstream, and already present in 4.18.14.
This would be upstream commit
daa07cbc9ae3da2d61b7ce900c0b9107d134f2c1 ("KVM: x86: fix L1TF's MMIO GFN calculation"). |
