According to: https://fedoraproject.org/wiki/Features/KVM_Huge_Page_Backed_Memory ...I should create /dev/hugepages and mounts hugetlbfs on it. But this is a hack. There needs to be some automatic way to ensure that /dev/hugepages exists and is mounted; I shouldn't have to do it manually. This is with libvirt-0.7.1-15.fc12.
Created attachment 390107 [details] patch to make /sbin/start_udev mkdir /dev/hugepages The attached patch makes /sbin/start_udev mkdir /dev/hugepages, the same way it creates other subdirectories in /dev that are mount targets. With this patch, the following line in /etc/fstab will do the trick: hugetlbfs /dev/hugepages hugetlbfs defaults 0 0
