one thing I discovered: When upgrading from XCP 1.5 (1.4.90) to 1.6 (61002c) 
the network backend is automatically switched from bridge to Open vSwitch. 
This is no bad idea in general, as Open vSwitch seems to work very well in 
1.6, but if you configured an (unsupported) LACP bonding interface by 
specifying some other-config settings for your storage bonding pif, you end 
up with a storage bond that does not come up after the upgrade because Open 
vSwitch doesn't like the options it gets passed in from the pifs other-
config settings. 

I wouldn't rate this as bug (maybe the forced switch of the network backend 
is?), as LACP was never supported in versions prior to 1.6, but a note in 
the release notes would be good.
