[Users] Question about veth interfaces

[Nathan Broderick]

Hi,

I have an installed system of OpenVZ and it works very well.  One 
question that I have is when we stop and start the veth interfaces 
(ifdown veth0; ifup veth0;) all the accounts on the system no longer 
will accept ssh incoming connections.  It almost seems like the routing 
on the accounts get changed.  Is there a better way to bring down and up 
the interfaces in case there is a problem?
