Red Hat Enterprise Linux 6.4 or 6.5 guests running on a Microsoft Hyper-V virtual machine may crash if the guest is configured with more memory or CPUs than can fit in a single NUMA node.
The guest stuck at the very beginning of booting:
Probing EDD (edd-off to disable)... ok ... ... PANIC: early exception 06 rip 10:ffffffff81c4b4ae error 0 cr2 0
To work around this issue, add the boot-time parameter "numa=off" to the kernel line of the virtual guest's grub.conf file to disable NUMA support in the guest. This parameter may cause performance implications for any guest that does not fit into a single NUMA node.
