'make check' fail in Debian VM

[kapiliitr]

I am getting errors during 'make check'. I am running debian sid-unstable in a KVM. I added <cpu mode='host-passthrough'/> to the libvirt XML file and below is the output for 'dmesg|grep PMU'
[ 0.024868] Performance Events: 16-deep LBR, IvyBridge events, Intel PMU driver.
[ 0.026318] perf_event_intel: PMU erratum BJ122, BV98, HSD29 workaround disabled, HT off

Below is an error that I am getting-

Does perf record work for you? It sounds like your system might be configured so perf events are only usable by root.

Yes, perf record worked for me but it wasn't installed.
Also, make check did run for root user, but now I am getting a new error.
Maybe I should create a new issue for that ?

Here is the log anyways-

OK, I just pushed a fix for the capget test.

You probably should configure your system to allow perf events to be used by non-privileged users, instead of running everything as root.
