[PVE-User] help please - upgrade v1.6 to v1.7 not so fine...

[Harald Kapper]

Hi

We got a currently working machine that goes in terms of vmbr like this:

 

bridge name     bridge id               STP enabled     interfaces

vmbr0           8000.00215e6725ce       no              eth0

                                                        vmtab5207006i0

vmbr1           8000.00215e6725cf       no              eth1.2305

                                                        vmtab5207006i1

vmbr2           8000.00215e6725cf       no              eth1.322

                                                        vmtab5207006i2

 

then there is a machine that has been upgraded to v1.7 fully that shows:

bridge name     bridge id               STP enabled     interfaces

vmbr0           8000.00215e6777b8       no              eth0

vmbr1           8000.00215e6777b9       no              eth1.2305

vmbr2           8000.00215e6777b9       no              eth1.322

 

if on this machine now a kvm-box tries to start it goes like this (and badly
wrong) :

qm start 5207007

got strange interface name 'vmtab5207007i0d'

/var/lib/qemu-server/bridge-vlan: could not launch network script

ge-vlan -device e1000,mac=2A:2C:99:17:83:07,netdev=vlan2d0' failed with exit
code 1

 

we finally tried to reboot the whole box - nothing changed, it won't fix and
start (we've seen before the need to restart bridges, but didn't help).

 

Any help appreciated as we have all boxes in this cluster configured like
this I see hell breaking loose.
