[Centos] Networks reachability breaks with tagged vlans

[Nikita Koshikov]

Steps to reproduce:
1)Create environment with Neutron_VLAN +HA mode on Centos
2)Deploy 1 controller + 1 compute.
3) When deployment finished there is no ping's between some networks(See below)

1) See attached screenshot_1
Management network + Private Network on the same interface, Storage on it's own.
Result - compute can't reach controller on management ip, but storage ip is pingable

2) See attached screenshot_2
Management network on separate interface, Private Network + Storage shares on interface
Result - compute can't ping controller by storage ip, but management ip - works

3) See attached screenshot_3
Management network + Storage network on 1 interface, Private - on another.
Result - compute can ping controller by both IPs.

This is manual deployment though fuel web UI.
Virtualization - libvirt+KVM

which interface model was used in libvirt while ENV was prepared?
Is it virtio, e1000 or anything else?

[Nikita Koshikov (nkoshikov)]

All interfaces are virtio.
This is related xml
    <interface type='network'>
      <mac address='52:54:00:94:54:82'/>
      <source network='br-ex'/>
      <target dev='vnet6'/>
      <model type='virtio'/>
      <alias name='net1'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
    </interface>

[Stanislav Makar (smakar)]

Tagged VLANs on CentOS do not work with virtio interface model at all.
Please use e1000, rtl8139 for CentOS .
