I have the following VM I am currently using to build software on:

Linux sclbuild 2.6.32-431.5.1.el6.x86_64 #1 SMP Wed Feb 12 00:41:43 UTC
2014 x86_64 x86_64 x86_64 GNU/Linux

It has this as the main filesystem:

/dev/mapper/vg_sclbuild-lv_root on / type ext4 (rw)

I am not having any issues with this Xen DomU VM, running on a
Xen4CentOS6 Dom0.
