| |
This series of patches fix various scenarios in which KVM behavior does not follow x86 specifications. Each patch actually deals with a separate bug. These bugs can cause the guest to get stuck (i.e., make no progress), encounter spurious injected exceptions, or cause guest code to misbehave. As a result guest OS can potentially fail.
Thanks for reviewing the patches.
