It means that the hypervisor recovered from #GP faults several times. What exactly it was that faulted you'd need to look up by translating the addresses above and resolving them to source locations. That'll also tell you whether you ought to be worried. A common example of these happening is Xen carrying out MSR accesses on behalf of the kernel, when the MSR actually isn't implemented (i.e. the kernel itself also is prepared to handle faults upon accessing them).
