KVM Issuse

So,

Having an issue with KVM on Ubuntu 14.04 that is driving me insane.

This is a new box, so I will go through what I did:

- Set up bonded NIC's. Failover, 1 active at a time
- Set up a bridge on top of that bond.

- Installed KVM on Ubuntu
- Installed virt-manager on Ubuntu

- Installed a VM without issue, but it wouldn't see the bridged interface, only virtual NAT.

- Shut down the VM to try and diagnose. VM now refuses to start due a connection error.

- Virt-manager and Virsh both refuse to create an VM's due to connection reset.

Here is my network config:

# The loopback network interface
auto lo
iface lo inet loopback
# EM1 Configuration
auto em1
iface em1 inet manual
bond-master bond0
bond-primary em1

# EM2 Configuration
auto em2
iface em2 inet manual
bond-master bond0

# Bond EM1 & EM2
auto bond0
iface bond0 inet manual
bond-mode active-backup
bond-miimon 100
bond-slaves none

# Bridge for Bond0
auto br0
iface br0 inet static
bridge_ports bond0
address 192.168.3.130
netmask 255.255.252.0
gateway 192.168.1.1
dns-nameservers 8.8.8.8
bridge-fd 9
bridge-hello 2
bridge-maxage 12
bridge-stp off

Anyone have similar issues? I've sat here for hours trying to find a fix to get any VM's created, but I'm hitting a brick wall.

If you use virt-manager you probably won't see the bridge, instead you can select "specify shared device name" on the NIC of your VM then you can enter br0 under "bridge".

Tried that, but it's still no go.

I can't even create new VM's atm, or start because they'll just error out:

@BUSNYVM01:/etc/libvirt/qemu# virsh -d 0 start BUSDJ01
start: domain(optdata): BUSDJ01
start: found option <domain>: BUSDJ01
start: <domain> trying as domain NAME
error: Failed to start domain BUSDJ01
error: Connection is closed
