Cannot deploy virt role with VLAN segmentation

[Dmitry Sutyagin]

Fuel 9.0, Neutron with VLAN segmentation, Advanced Features enabled

Trying to create an env with virt role fails on "Provision VMs" step due to the following error in /usr/bin/generate_vms.sh:

2017-01-18 00:43:45 +0000 /Stage[main]/Osnailyfacter::Generate_vms::Generate_vms/Exec[generate_vms]/returns (notice): error: Failed to start domain 111_vm
2017-01-18 00:43:45 +0000 /Stage[main]/Osnailyfacter::Generate_vms::Generate_vms/Exec[generate_vms]/returns (notice): error: Cannot get interface MTU on 'br-mesh': No such device

Also, documentation for virt role is very sparse, "Reduced Footprint" only appears on "Reinstall a virtual role" page, and there is no doc on using virtual role in general, so if there are limitations they aren't public.

Dmitry, it would be really useful to have a little bit of logs.

I'll reproduce once more and attach logs later today. The point is that with VLAN segmentation there is no "br-mesh", so obviously there's some hardcoded logic in generate_vms or relevant place which won't work with VLAN segmentation networking. This is 9.0, have not tried on 9.1+

bummer, I actually tried with 10.0 and it also fails. Anyway, logs will follow later today.
