Starting recently libbpf CI runs started failing with the following
error:
##[group]vm_init - Starting virtual machine...
Starting VM with 4 CPUs...
INFO: /dev/kvm exists
KVM acceleration can be used
Could not access KVM kernel module: Permission denied
qemu-system-x86_64: failed to initialize KVM: Permission denied
##[error]Process completed with exit code 2.
E.g. see here [0]. The error happens because CI user has not enough
rights to access /dev/kvm. On a regular machine the solution would be
to add user to group 'kvm', however that would require a re-login,
which is cumbersome to achieve in CI setting.
Instead, use a recipe described in [1] to make udev set 0666 access
permissions for /dev/kvm.
