[ovirt-users] VM Network Interfaces - bad cluster network and VLAN assignment

[David Jaša]

Ahoj Jiří,

Are you sure that the networks are indeed wrong, for example that
guest's NIC with ...:11 MAC is plugged to br0 network and ...:ef NIC is
plugged to br1 network? If so that would be a serious bug. I thing
however that you just see guest OS NIC naming race conditions, maybe if
ovirt's NIC names would be prefixed with nic- instead of eth- by
default, such confusions wouldn't happen...

For some reference, bug [1] is implemented consistent NIC order in the
portal and [2] to be able to modify pci addresses as well (as they are
used by some OSs to base NIC naming on).
