Xen fixes kernel crash
The Xen Project's latest bug means hugetlbfs can crash some Linux VMs.
Explained here, the flaw means apps that use hugetlbfs inside a paravirtusalised guest "would cause an infinite page fault loop, and an OOPS to occur upon an attempt to terminate the hung application."
All x86 Linuxes are susceptible to the flaw, which can be patched with this code.
Or you could just bin hugetlbfs, which is a sensible idea anyway because paravirtual guests are generally not allowed access to huge pages. ®
