I must be using a different version on Mint/Ubuntu: Virtual Machine Manager 0.9.5 I don't have any options on 2nd screen. I assume we are talking about the Host "Connection Details" screen. I'm getting to this by right-click on remote host (QEMU) and selecting "Details". Second tab is "Virtual Networks" and I click the "+" button to create a new network. Second screen only allows me to enter the CIDR. Next screen enable/disable DHCP (and assign pool.) Next screen has option to connect to physical network or keep "Isolated virtual network". Last screen is a summary before creation. Should I be using a different client to manage Host remotely?

Not sure if I can create an isolated network from VM Manager.I just tried it and yes it is possible. On the 2nd screen where it asks for IPv4 info, just uncheck the "Enable IPv4" checkbox, then on screen 4, clear out the "DNS Domain Name" at the bottom of the page. This will give you a virtual network with a bridge created by libvirt, but no IP address on the bridge itself, so no traffic will be able to go to/from the host from that bridge. The only other bit you'll need to do is setup the dhcp server on the router guest.
Sorry, just realized there is a VMmanager app too (free version seem to only have support for Debian 7 though.) I am using the Virtual Machine Manager GUI (virt-manager.) -----Original Message----- From: Laine Stump <laine@laine.org> To: libvirt-users@redhat.com Cc: shorawitz@gmail.com Subject: Re: [libvirt-users] Isolated networks && test lab Date: Thu, 27 Aug 2015 19:26:03 -0400 On 08/27/2015 07:13 PM, Spanky Horawitz wrote:> > Thank you!
