Thanks. The bridges are preconfigured at the box. No issues there. Can I assign a second physical NiC as a second interface at the KVM? Can I do it at the installation time using virt-install? Can I do it by editing a file after the KVM is created? I would like to automate things. Thank you

You can try to assign each bridge to its own individual virtual NIC in VM, at least it works with virt-manager + libvirt + qemu-kvm with preconfigured bridges.

Hello Everybody,

I have a physical machine with 4 Ethernet cards that I have mapped to 4 bridges.

I would like to have each of my KVMs use 2 bridges for NIC bonding.

1.   Can I have more than one bridge assign to one KVM?
   
   

2.   Can I use virt-install to assign a KVM with more than one bridge during the KVM installation?
   
   

a. It was a long shot but I have tried bridge=br0,br1 ; bridge=br0 bridge=br1 – never worked…..

Thanks so much,

Meir

Thanks,

This is what I'm getting,

ERROR Unknown argument 'bridge:br0'

-This is the command,

virt-install -n $machinename -r $memory --vcpus=$cpus --os-variant=rhel6 --accelerate -v -w --network bridge:br0 --network bridge:br1 --disk path=/home/vm/$machinename.img,size=100 -l http://172.21.110.213/6.3/ --nographics -x "ks=http://172.21.110.213/KS/$machinename-ks.cfg ksdevice=eth0 ip=172.21.110.248 netmask=255.255.255.0 dns=172.21.110.2 gateway=172.21.110.1 console=ttyS0"

-The following is working,

virt-install -n $machinename -r $memory --vcpus=$cpus --os-variant=rhel6 --accelerate -v -w bridge:br0 --disk path=/home/vm/$machinename.img,size=100 -l http://172.21.110.213/6.3/ --nographics -x "ks=http://172.21.110.213/KS/$machinename-ks.cfg ksdevice=eth0 ip=172.21.110.248 netmask=255.255.255.0 dns=172.21.110.2 gateway=172.21.110.1 console=ttyS0"

-What am I doing wrong?

Thanks so much,

As far as I know the only way to directly assign real NICs into VM without bridging is to use PCI passthrough, though this way imposes several limitations, mostly in IOMMU / VT-d hardware support.

But if bridging is acceptable then you can repeat --network bridge:<hypervisor_bridge_nic> option in virt-install command line several times to create as many NICs inside VM as you want.
