Description
head -n0 /dev/hpet (should do open() without reading) causing xenserver VM reboot.
i can reproduce this on Centos 7.4 VM on XS7.0 and XS7.2 but not on vSphere 6.5
uname -a

cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)
Not sure if it`s a guest-OS or hypervisor issue, though...
