Vagrant: Passing docker run arguments to multiple containers using vagrant

|▌冷眼眸甩不掉的悲伤 提交于 2021-02-11 04:34:25
问题 I'm using vagrant to deploy a multiple VM environment, for research purposes, and it was great so far. But now i need to pin each docker container to a specific CPU core, but i don't know how to do that using vagrant. I know i can use the "args" clause on the Vagrantfile to pass the "--cpuset" parameter to the docker run command, but i don't know how to use it in a loop, since i'm launching multiple containers and i need to pin each container to a different CPU core (eg. node1 pins to core #0

问题 For purpose of creating bulk virtual machines, I need to create a random MAC address generator in Python. I don't know how to generate random MAC addresses. Is the following program correct or not? import random # The first line is defined for specified vendor mac = [ 0x00, 0x24, 0x81, random.randint(0x00, 0x7f), random.randint(0x00, 0xff), random.randint(0x00, 0xff) ] print ':'.join(map(lambda x: "%02x" % x, mac)) 回答1: For anyone wanting to generate their own MAC addresses (a good example is

Convert qcow2 to vmdk and make it ESXi 6.0 Compatible

て烟熏妆下的殇ゞ 提交于 2021-02-06 04:53:21
问题 I am currently working on VMWare virtualization; I am trying to make a converted image from qcow2 to vmdk work with ESXi Server 6.0. I have myImage.qcow2 with a disk which is thin provisioned for 300GB. I used the image converter tool qemu with the following command qemu-img convert -f qcow2 myImage.qcow2 -O vmdk myNewImage.vmdk This command gives me a vmdk image which is only VMWare Workstation compatible. Therefore, in order to make it ESXi compatible I have to use the vmkfstools with the

Forward packets between SR-IOV Virtual Function (VF) NICs

问题 I have an Intel 82599ES 10G NIC which supports Intel SR-IOV. I have successfully created 8 virtual functions (VF) of it and assigned to 2 qemu/kvm VMs (2 VFs per each VM). Both of the VMs run DPDK applications (warp17 on one and my custom application on other) using assigned VFs. What I need to do is test my custom DPDK application by sending traffic through it using warp17. My test setup looks like this, The red arrow represents the traffic path. My Physical NIC (PF) use dpdk poll mode
