Re: [Xen-users] Copy files from Centos Guest to Host

[Rakesh Chawda <rakesh@xxxxxxxxxxxxxxxxx>]

Yes, Grant. I have multiple DomU's atached to the same bridge. And both the IPs are of same subnet. I just used scp, and it worked fine, as it happens normally. The only question, was any internet involved? Just for knowledge.

The IPs are like a.b.c.1 and a.b.c.2.

So, for the first 4 options, I'll have to use internet

Can I, by any chance, setup any internal networking like NAT or something, by which I can transfer files directly, i.e without internet?

The only requirement is that they can be reached by IP packets from each other. Whether this is available in your current configuration depends on your config.

But taking a  setup : Both Dom0 and guests are on a common private network behind a NAT gateway; just access other systems by their private (RFC1918) addresses - no internet involved.

Alternatively, you can add a private internal network which is completely separate from other networking. Add a bridge on Dom0 which has no physical interfaces attached to it. Add a second VIF for each guest that is attached to this bridge. Give them all RFC1918 addresses and you have a private network between host and guests. If you want this private network to extend to other hosts and guests on it, or to your internal network, then connect a physical interface to it.

 

I think from his original post he has multiple DomU's plugged into the same bridge so all he has to do is scp between the IPs and be done with it.  If those bridges are on different subnets then we have a different situation.
