I also had problems with open-vswitch and XCP 0.1.1 pools (standalone hosts work fine) while trying to use a vlan-tagged interface as a management interface (with and without bonded interfaces).
I know this is unsupported even in XenServer (before XCP), but I was able to do it with xe emergency-transition-to-master for each host inside the pool. After all hosts have the management on vlan-tagged interfaces, I just rebuild the pool. On XCP 0.1.1, I first created the Network/VLAN pair in all hosts inside the pool using the xe CLI (xe pool-vlan-create). Then, through pool's master xsconsole, I changed master's management to the vlan-tagged interface. At this moment, the master lost communication with other hosts in the pool, as expected. Then, I went to one of the slave hosts and made it a temporary master (xe emergency-transition-to-master). The problem is that when I set the vlan-tagged interface as the management, the host somehow starts to communicate with the original master and open-vswitch cuts the link between then. I could see that the vlan-tagged port inside open-vswitch went down at one of the sides (I'm almost sure at original master's side). I'm sorry I don't have logs anymore and I'm not really sure this is a bug. But with XenServer 5.5.x (in regular bridge mode) this works just fine. I guess this may be not a very common requirement, but in my case the management interface must be vlan-tagged and bonded. For me, it's a blocker and I would be glad to help further investigating the issue.
