[Vm-dev] 64bits Guardian failure on Squeak 5.3 RC1

[Nicolas Cellier]

Well, I've tried to install rr and all its dependencies on Ubuntu 16...
But...
I have no available machine to run linux natively.

To run rr inside a virtual machine, virtualization of perf counters needs
to be enabled...
https://github.com/mozilla/rr/wiki/Building-And-Installing

I'm using parallels, but not the Pro version, because I don't like the
annual pricing model, for personal use it's just too much.
Unfortunately, only pro edition supports PMU virtualization
https://download.parallels.com/desktop/v11/docs/en_US/Parallels%20Desktop%20User%27s%20Guide/37830.htm

Maybe it's time to change of VM provider, but for now, that's too many
hurdles, I give up...
