2017-11-28 23:06:03 -0500 asked a question tx rx count not increasing
 Hello Team

I'm having couple of VMs running on compute node and when I'm trying to ping outside from the VMs,the Tx,Rx count of the VM is not increasing.

However I'm able to ping the local Ip from both the VMs.

Hi Team

I'm having multi node Openstack Mirantis setup and I have upgraded the same setup with OVS-DPDK.I'm having 2 VMs running with same fixed virtual network on same compute node but still they are not able to ping each other.

Let me know the possible solution for this.

2017-09-21 07:47:25 -0500 asked a question cpu pin with nova
 Hi Team

I need to map the vcpu associated with the Openstack vnf with the physical cores 6,7 of the host.For this,I have added below lines in nova.conf..

vcpu_pin_set = 6,7

Also for better performance,I have isolated  the above cores from the host process using isolcpus in /proc/cmdline.Below is the output of /proc/cmdline..

BOOT_IMAGE=/boot/vmlinuz-4.10.0-35-generic root=UUID=f3d92ebb-a521-49c5-9a88-1b8b4947591d ro default_hugepagesz=1G hugepagesz=1G hugepages=16 hugepagesz=2M hugepages=2048 iommu=pt intel_iommu=on isolcpus=2,5,6,7

Below is the flavor details..

Hi Team

I'm able to run docker containers on arm64 compute node and able to login into it. However due to some specific reason, I need to run docker containers with --net=host as a parameter.

Please let me know how can we do that with nova using OpenStack.
