perf machine: Do not require /lib/modules/* on a guest For some types of work loads and special guest environments, you might have a kernel that has no kernel modules. The perf kvm record tool fails instantiate vmlinux maps when the kernel modules directory cannot be opened, even though the kallsyms has been properly processed. This leads to a perf kvm report that has no guest symbols resolved. This patch changes the failure to locate kernel modules to be non-fatal.
