[Xen-API] [XCP 1.5 Beta] Open vSwitch issues

[Eugene Chupriyanov <e.chupriyanov@xxxxxx>]

Hi,

I'm having some obscure networking issues on XCP 1.5 beta. I have 
following configuration in  my lab:
1) Pool 1, 2 hosts
Host A (IBM x3650), 2 BCM5708 NICs
Host B (HP Proliant DL320 G5) 2 BCM5714 NICs

NIC 0 on both hosts used exclusively for management
NIC 1 has several VLANs with attached VMs

Pool was upgraded from XCP 1.1 release to XCP 1.5beta
 After upgrade I've noticed that VMs on Host A are working perfectly, 
but on Host B we have network probles: I can ping to/from VMs, but TCP 
sessions almost unusable (timeout all the time). If I switch Host B to 
bridge more (using /etc/xensource/network.conf) everything works perfectly.
2) Also I have a standalone clean XCP 1.5 beta install from scratch on a 
Host identical to Host be in case 1.
It also has the same network problems. But if I try to switch bridge 
mode in network.conf it boots without network setup at all.
Does it mean, that bridge mode will not supported anymore? How can I 
tune open vSwitch to fix these issues.
Thanks in advance,
Eugene
