The $VM name is used also as hostname in the guest so ssh connection can
be made to root@$VM. However, valid hostnames can only contain letters,
numbers and '-'. If other characters are used, they are removed from the
hostname so you cannot connect to root@$VM. Fix it by not allowing
invalid hostnames in $VM at VM creation.
Also, fix some incorrect bash regexes.
Install missing repositories required to install all the packages.
Unluckily, it doesn't support 9P filesystem shares, and virtiofs is not
supported for non-root hosts. Emit a warning about that.
Images of qcow2 format dynamically grow up to the maximum size that they
have been configured at creation time. Because of this, higher size can
be selected without wasting unnecesary space in the host. Rise image
size to 20G.
Also, allow to set an empty value to IMAGE_SIZE, and don't resize in
that case. This is useful because virt-resize fails with some guest
partition layouts (like with ubuntu-20.04).
Using more than one VM can be a quite common use case. Insteado of
having to do VM=vm_name ./nm-in-vm, allow the more common way of passing
options ./nm-in-vm --vm vm_name.
Also, in build command, accept one positional argument to set OS_VERSION.
The connectivity with the host depends on getting a DHCP lease from the
host. With the latest commit's customizations, the virtual NIC is not
managed by NM so it is not configured.
Keep it unmanaged so debuging NetworkManager doesn't affect to this
virtual NIC. Use dhclient to get a DHCP lease from the host. Assign a
fixed interface name (host_net) to match it from NM and dhclient config
files.
Script to download, configure and install a virtual machine to build and
test NetworkManager. This is useful because there are some things that
doesn't work properly on containers so a VM is needed to test.
It works almost the same way than nm-in-container.
Configurations specific to NetworkManager such as installing the required
packages are not implemented yet.
