Xen/MCE: vMCE injection In our test for win8 guest mce, we find a bug that no matter what SRAO/SRAR error xen inject to win8 guest, it always reboot. The root cause is, current Xen vMCE logic inject vMCE# only to vcpu0, this is not correct for Intel MCE (Under Intel arch, h/w generate MCE# to all CPUs). This patch fix vMCE injection bug, injecting vMCE# to all vcpus. Signed-off-by: Liu,

Hello! The current MCA/MCE support in Xen is that it dumps the error and panics. In the following concept I propose here, there are two places where Xen has to react on. I) Xen receives a MCE from the CPU and II) Xen receives Dom0 instructions via Hypercall The term "self-healing" below is used in the sense of using the most propriate technique(s) to handle an error such as MPR
