KVM can't handle the values written MSR_IA32_MC4_CTL

Consequence:

Workaround (if any):

Result:
Cause:
KVM can't handle the values written in MSR_IA32_MC4_CTL by Linux guests when using some CPU family/model values (including the ones for the Opteron_G3 CPU model).

The mce_init() function on the Linux guest will trigger a General Protection Fault.

More recent Linux guests (RHEL-5 and newer) are (incorrectly) ignoring wrmsr exceptions, so they are not being affected.

Consequence:
RHEL-4 guests will panic when booting.


Workaround (if any):
1) Use "nomce" kernel command-line option on the guest (will disable MCE support); or
2) Use a different CPU model name on the VM configuration.


Result:
Guest should boot normally.

Result:
Guest should boot normally.
KVM (Kernel-based Virtual Machine) cannot handle the values written in the MSR_IA32_MC4_CTL preprocessor macro by Linux guests when using some CPU or family model values. As a consequence, kernel panic occurs when booting on Red Hat Enterprise Linux 4 guests. Red Hat Enterprise Linux 5 and later incorrectly ignore certain exceptions so they are not affected. To work around this problem, use the nomce kernel command-line option on the guest, which disables MCE support. Alternatively, use a different CPU model name on the virtual machine configuration. As a result, guests boot as expected and kernel panic no longer occurs.
