You'll have to provide a shorter "linux"-grub-line than what's written in the "grub.conf"-file; some- thing like this: linux /vmlinuz-2.6.32-431.el6.x86_64 ro root=/dev/mapper/VolGroup-lv_root initrd /initramfs-2.6.32-431.el6.x86_64.img or else the LVM-groups won't get activated. >> Ping times to the VM are fluctuating - ranging from 0.185ms to 35ms. > > Hmmm, will look at that as well.
