I have just carried out a rolling pool upgrade of a 3-host pool from XCP 1.1.0 (50674c) to XCP 1.6 Beta (61002c). I was able to bring up the VMs as normal and network connectivity is ok. However when I tried to implement the first change I encountered a problem. I tried to change a vif from one network (a physical interface eth0, network uuid ef66fdda-e249-a01d-545c-e002f945bdc6) to another (a pool vlan 255 on a bonded interface bond0 created with slaves eth1 and eth2, network uuid 7568abf3-470f-21fc-9ec2-24e854d4522c). The vif-destroy and vif-create process were executed as normal, but on attempting to start the vm, I got an error saying "stderr = ovs-vsctl: cannot create a port named eth1 because an interface named eth1 already exists on bridge xapi3". My network configuration, on each of the 3 hosts, is: interface bond eth0 n.a. eth1 bond0 eth2 bond0 eth3 bond1 eth4 bond1 eth5 bond2 eth6 bond2 I have a number of pool vlans created on bond0 and bond2. The particular vlan involved in this report is vlan255, corresponding to an 802.1q tag of 255, created on bond0 The command log follows. The vm and previous vif had their parameters listed prior to the change. The attempt to startup the vm results in the error. I thought it was strange that ovs-vsctl is attempting to add eth1 to the bridge xapi3 (which corresponds to bond0) when the vm starts - I would have expected this to take place on xenserver startup. I have carried out this operation prior to the upgrade dozens of times, so I know it should work. I'd be grateful for any advice.
