The code in vpmu_initialise() already subtracts 1 from the vpmu_count in the Intel case. Won't this now cause an underflow when shutting down a VM which didn't enable vpmu to start with? ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel
