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: (On Workstation 10, the e1000 gave a corrupted vmx file. Using V6 machine type did work. So it seems somewhere between V6.5 and V10 VMware dropped support for the e1000 driver and/or the virtualDev keyword.)
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:
ifconfig | moreto see the DHCP assigned IP address for the Bridge assigned to the NIC
iperf3 -c <ip-address-of-the-server>
Here are some results from my system:
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:
dd if=/dev/sdb of=/dev/sda
fdisk /dev/sdaand write the partition table (without making changes, this helps sysrescuecd to see the partitions properly)
fsck -fon the sda2 partition
fdiskresize the sda2 partition to occupy all the space available (but still starting with the same sector of before, normally 9135)
fsck -f /dev/sda2
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?
