vagrant setup fail witrh libvirt provider...

[mcarbonneaux]

i'm on ubuntu 20.04 with vagrant 2.2.6 with libvirt.

i try to use vagrant to setup a test explained in https://github.com/github/glb-director/blob/master/docs/setup/example-setup-vagrant.md.

my first problem has been with /vagrant that are configured with nfs, and in server they don't found the vm ip to configur the nfs exports... i've added the next line to overide nfs default configuration (added after src/glb-wireshark-dissector sync folder):

config.vm.synced_folder ".", "/vagrant", type: 'rsync'

then when try to install dpdk-rte-kni-dkms dpdk-igb-uio-dkms they cannot because they are not authenticated package....
i've added "--allow-unauthenticated" on apt install.

sudo apt install -y --allow-unauthenticated dpdk-rte-kni-dkms dpdk-igb-uio-dkms

but after the rte_kni and igb_uio are not in kernel module directory...

then i found that memory and cpu are sized only on virtualbox provider... because i've seen many fork fail...

i've added the rigth size also for libvirt provider:

v.vm.provider "libvirt" do |vb|
  vb.cpus = 3
  vb.memory = "2048"
end

after the kernel module load correctly.

after the interface name are not ethx in last debian image... now are ensxxx...

i've changed eth1 with ens6 in Vagrantfile and ./script/helpers/configure-vagrant-director.sh.

now i'm blocked on director2 xdp that say this error message:

i've resolved the last one in using e1000 driver in libvirt conf virt.nic_model_type = "e1000".

i've found many other problem, like interactive apt installation that not build dpdk driver using DEBIAN_FRONTEND=noninteractive before apt-get install to resolve.

lldb v9 that do not whant to install dev part that not exist in llvm stretch repo... i've used v10 in place.
