I am still playing with KVM, and will more than likely setup my lab as you suggest in order to isolate the guests from the host. Not sure if I can create an isolated network from VM Manager. -----Original Message----- From: Laine Stump <<A HREF="mailto:Laine%20Stump%20%3claine@laine.org%3e">laine@laine.org</A>> To: <A HREF="mailto:libvirt-users@redhat.com">libvirt-users@redhat.com</A> Cc: <A HREF="mailto:shorawitz@gmail.com">shorawitz@gmail.com</A> Subject: Re: [libvirt-users] Isolated networks && test lab Date: Thu, 27 Aug 2015 18:43:04 -0400 On 08/27/2015 02:48 PM, Spanky Horawitz wrote: <BLOCKQUOTE TYPE=CITE> Lesson learned.

As long as you don't care that the guests can reach the host if they really want to, and you have the guest IP configuration done manually, this won't be a problem. If you're really pedantic about isolating the guests from the host and/or need them to get their IP address from DHCP, then you'll need to do what I described in the other message. <BLOCKQUOTE TYPE=CITE> Side question: where are the virtual networks stored when you create them w/VM Manager? </BLOCKQUOTE> They are stored in /etc/libvirt/qemu/networks, but you should never access/modify those files directly. Instead, use "virsh net-dumpxml $netname" to look at the config of a network, and "virsh net-edit $netname" to modify it (or variations of "virsh net-update $netname..." to make some changes that can be done without shutting down/restarting the network). </BODY> </HTML>
