That's a known bug that I believe has been fixed with 3.18.25-something. "Can't find rootfs" is most likely the missing initrd bug, which is fixed in centos-release-xen-7-12 or later. You can: 1. Manually add the initrd line to the xen stanza in /boot/grub/menu.lst, or 2. Upgrade to centos-release-xen-7-12 or later, and then 2a. Run grub-bootxen.sh manually, or 2b. Update the kernel (which will cause grub-bootxen.sh to be run automatically). Peace, -George
