Hi All,

I have two computes

Compute node 1:
1. physnet3:br-eth0

2. physnet2: br-eth2

Compute node 2:
1. physnet3:br-eth0
2. physnet1:br-eth1
3. physnet2:br-eth2

When I boot an instance with a network of provider-network physnet1,
nova is scheduling it on compute1 but there is no physnet1 on compute1
and it fails.

Is there any mechanism/way to choose correct compute with correct
provider-network?

Well, the --availability-zone option can be given a host name separated from an optional actual availability zone identifier by a colon:

nova boot .. --availability-zone :hostname ...

But specifying a specific host rather than just an availability zone requires the project to have forced_host (or is it force_host?) capabilities. You could, perhaps, define the two computes to be separate availability zones to work around that.
