[libvirt] hugepages error: "hugetlbfs filesystem is not mounted"

[Shahar Havivi]

Hi,

I am trying to run a VM (via VDSM) with hugepages and I am getting this error:
"virNetClientProgramDispatchError:170 : internal error hugetlbfs filesystem is not mounted"


hugepages is mounted with the proper permissions (36:36) in case of vdsm user,
this code use to work..., now I am at version: libvirt-0.9.4-12.el6.x86_64

output of few commands:

# tree /dev/hugepages/
/dev/hugepages/
`-- libvirt
    `-- qemu

# ll -n /dev/hugepages/libvirt/
total 0
drwxr-xr-x 2 36 36 0 Oct  3 12:46 qemu/

# sysctl vm.nr_hugepages
vm.nr_hugepages = 256


Any idea whats wrong?

Thank you,
