Hi all, How can I see what vnet is attached to a certain kvm guest?? For example: I have a kvmguest1. When I launch this guest with virsh command, virsh creates a new vnetX interface for this guest. How can I extract this virtual net interface (vnet0, vnet1, vnet2 or so on) using a script?? Thanks. -- CL Martinez carlopmart {at} gmail {d0t} com

I am running KVM virtualization with libvirtd (libvirt) 0.10.2 in bridged network mode, however I still have the default virtual network bridge/interfaces and dnsmasq on the host. What I am trying to understand is whether or not dnsmasq and the virtual network (*virbr0, Vnet0 and Vnet1*) still play any role. If not, can I remove them? On most virtual hosts I see they are left around even when a network bridge has been manually setup and the default virtual network bridge/interfaces and dnsmasq are not serve any purpose. Thanks Mimi [bigfoot@localhost ~]$ ifconfig br0...

I have a computer I am using to host a virtual machine. Centos 6, for both, 64 bit. The host machine's network connection seems fine. No problems. Trying to access the virtual machine is usually fine. but then, poof, ssh, http, ftp, all lose connection for about a minute. Then they come back up. I looked in all the logs on both machines, could find nothing, but not sure where to look. My

Hi! I'm aware that (host side) vnetX are created when VM boots. But I'm trying to figure out a way ti create a persistence in vnetX names. What I mean is, say, I want to associate VMs vm0 to vnet0, vm1 to vnet1, vm2 to vnet2 and so forth, no matter which order the VMs are booted. I looked around network XML format, but did't find something...
