This article describes how to use OpenWRT as a virtual machine with VMware virtualization.
First of all, you need to download the image from list above on your machine. After that you extract & convert it to a vmdk image:
gunzip openwrt-x86-generic-combined-ext4.img.gz qemu-img convert -f raw -O vmdk openwrt-x86-generic-combined-ext4.img openwrt-x86-generic-combined-ext4.vmdk
yum -y install qemu-img wget https://downloads.openwrt.org/chaos_calmer/15.05/x86/64/openwrt-15.05-x86-64-combined-ext4.img.gz gunzip openwrt-15.05-x86-64-combined-ext4.img.gz qemu-img convert -f raw -O vmdk openwrt-15.05-x86-64-combined-ext4.img openwrt-15.05-x86-64-combined-ext4.vmdk
or on a Mac
brew install qemu qemu-img convert -f raw -O vmdk ~/Downloads/openwrt-15.05-x86-64-combined-ext4.img openwrt-15.05-x86-64-combined-ext4.vmdk
after that, just create a new VM in Fusion, Workstation, or ESXi with "Linux\Other Linux 32-bit" with LSI BUS Logic & add the vmdk there. Use Intel PRO/1000 Network adapters. This may require editing the .vmx file to include following definition:
ethernet0.virtualDev = "e1000"
On Fusion I had to use the IDE drive controller type.
Follow these steps to get an Up to Date VM with the latest code running on ESX in 15 minutes:
As you can see - the OpenWRT virtual machine running on VMware ESX is very capable of keeping up with your home internet router needs! And this is with only 1 virtual CPU and no tuning at all.
Here's a wish list of things we would like to accomplish with OpenWRT - consider this technical debt.
(Is there a better place to make these requests?)
Disk size and problems with veeam backup and enlarging the disk Veeam backup and vmware will complain about the size of the virtual disk provided by the openwrt download because the disk is not multiple of 1KB. (this means: no backups available, and could be crucial in production environments)
Vmware won't let you enlarge the disk in the normal way, so one simple way is:
. make a snapshot of the vm, for possible rollback . move the original disk (from openwrt downloads) on ide 0:1 . add a new disk, with a whole size, like 128 MB , on ide 0:0 . use sysrescuecdiso . start the vm with the iso . with dd copy the disc on ide 0:1 to ide 0:0 like dd if=/dev/sdb of=/dev/sda . enter fdisk /dev/sda and write the partition table (without making changes, this helps sysrescuecd to see the partitions properly) . do fsck -f on the sda2 partition . with fdisk resize the sda2 partition to occupy all the space available (but still starting with the same sector of before, normally 9135) . use resize2fs /dev/sda2 . do fsck -f /dev/sda2 . restart the machine and boot with openwrt check that the system uses the new partition . stop the machine, delete the previous hd (with less than 128mb) . restart the machine and verify that everything is ok.
Please use these images in your home and work labs and provide any feedback you might have.
Feel free to update this wiki page with your results.
There is some feedback that the newer images are not booting properly. Has anyone else run into this issue?
@iben learn , well, your quickstart ova works great. Following the instructions in the paragraph above it by the letter doesn't. /shrug .— Phoenixxl (@Phoenixxl) September 11, 2016
