The Xen Project reports:

HYPERCALL_xenoprof_op and HYPERVISOR_xenpmu_op log some errors and attempts at invalid operations. These log messages are not rate-limited, even though they can be triggered by guests.

A malicious guest could cause repeated logging to the hypervisor console, leading to a Denial of Service attack.
