Subject: Re: [ovs-discuss] VM doesn't power on after open vswitch installation


I've not seen that error before, and we run that version of XenServer 
nternally.  Doing a Google search for that error message (minus the "CentOS" 
arts) brought up a couple of suggestions of places to look.  You may just want 
o do a quick sanity-check of those suggestions first.  If that doesn't get you 
nywhere, can you run the following commands and post the results?
    xe pif-list params=all
   xe network-list params=all
   xe vif-list params=all
   ifconfig -a
Are you using the spec file in the "xenserver" directory to build your own RPM? 
 
f not, are you still using the scripts located in that directory?

 Xen kernel version is 2.6.18-128.1.6.el5.xs5.5.0.505.1024xen.
 Guest OS is Cent OS 5.0.
  
 Related to this issue
 With Open vSwitch running on Xen Server, If I try to create new VM with single 
nterface, Add VM failed with following error.
 Error: Creating 'CentOS 5.3 ' by cloning 'CentOS 5.3' - This VM cannot be 
tarted, as its network interfaces could not be connected.  One of the NICs is 
n use elsewhere.

 I've never seen anything like that.  If you remove Open vSwitch, does it work 
 again?
 
 What hypervisor are you using?  What guest OS are you using?
