perf kvm: Introduce option -v for perf kvm command.
As there is no -v option for perf kvm, the all debug message for perf
kvm will nerver be printed out to user.
Example:
# perf kvm --guestmount /tmp/guestmount/ record -a
Not enough memory for reading perf file header
It is confusing message for newbies such as me. With this patch applied,
we can use -v option to get the detail.
Example:
# perf kvm --guestmount /tmp/guestmount/ record -a -v
Can't access file /tmp/guestmount//15069/proc/kallsyms
Not enough memory for reading perf file header
