Re: [libvirt-users] Isolated networks && test lab

Thanks again! Can you tell me the difference in setting things up that way as opposed to updating (in Ubuntu) /etc/network/interfaces and adding physical br(idge) interfaces? On my other test box, I setup networks the way you describe from https://help.ubuntu.com/community/KVM/Networking -----Original Message----- From: Laine Stump <laine(a)laine.org&gt; To: libvirt-users(a)redhat.com Cc: shorawitz(a)gmail.com Subject: Re: [libvirt-users] Isolated networks && test lab Date: Thu, 27 Aug 2015 20:52:04 -0400 On 08/27/2015 08:25 PM, Spanky Horawitz wrote: virt-manager is what I'm talking about (don't know what you mean by "VMmanager"). Probably the dialogs have changed - mine is v1.2.1. 0.9.5 sounds a bit old, you should see if there is a backport of a newer version somewhere for whatever distro you're running. Alternately, it is dirt simple to create a new network that has no IP address associated with it. Just do this: 1) create a file with these contents: <network> <name>mynetname</name> </network> 2) "virsh net-define filename.xml" (where filename.xml is the file containing the above XML) 3) "virsh net-autostart mynetname; virsh net-start mynetname" (all these run as root)
