Since 0.1.0, the commands have been renamed to vsbmc and vsbmcd to allow coexistence with the original VirtualBMC. Also, the path to the configuration files has been changed.
To migrate your old configuration files, please refer to the migration guide on the GitHub Wiki page.
A virtual BMC for controlling virtual machines using IPMI commands for the VMware vSphere environment.
In other words, this is the VMware vSphere version of VirtualBMC part of the OpenStack project.
This can be used as a BMC of Nested-ESXi, therefore you can make the vSphere DPM work in your nested environment for testing purpose.
See:
- 📖The guide to use with Nested-ESXi and vCenter Server.
- 📖The guide to use with Nested-KVM and oVirt.
- 📖The guide to use with OpenShift Bare Metal IPI.
- For testing purposes only. Not for production use.
- The vCenter Server credentials including password are stored in plain text.
- The vSphere DPM can be enabled with VirtualBMC for vSphere, but be careful with the recommendations presented in the vSphere DPM in nested environments may not be accurate or meet expectations. See the wiki page for detail.
python -m pip install vbmc4vsphereIf you want to run VirtualBMC for vSphere in Docker container, see the guide on wiki page.
The following are the minimum permissions needed on vSphere for VirtualBMC for vSphere (queried using govc).

Install VirtualBMC for vSphere on some linux host, start vsbmcd daemon, and then configure through vsbmc command.
python -m pip install vbmc4vsphere-
Start daemon:
vsbmcd
By default, daemon starts in background. You can start it in foreground by
--foregroundoption to get logs.vsbmcd --foreground
-
In order to see all command options supported by the
vsbmctool do:vsbmc --help
It’s also possible to list the options from a specific command. For example, in order to know what can be provided as part of the
addcommand do:vsbmc add --help
-
Adding a new virtual BMC to control VM called lab-vesxi01:
vsbmc add lab-vesxi01 --port 6230 --viserver 192.168.0.1 --viserver-username vsbmc@vsphere.local --viserver-password my-secure-password
- Binding a network port number below 1025 is restricted and only users with privilege will be able to start a virtual BMC on those ports.
- Passing the credential for your vCenter Server is required.
- By default, IPMI credential is configured as
adminandpassword. You can specify your own username and password by--usernameand--passwordat this time.
-
Adding a additional virtual BMC to control VM called lab-vesxi02:
vsbmc add lab-vesxi02 --port 6231 --viserver 192.168.0.1 --viserver-username vsbmc@vsphere.local --viserver-password my-secure-password
- Specify a different port for each virtual machine.
-
Starting the virtual BMC to control VMs:
vsbmc start lab-vesxi01 vsbmc start lab-vesxi02
-
Getting the list of virtual BMCs including their VM name and IPMI network endpoints they are reachable at:
$ vsbmc list +-------------+---------+---------+------+ | VM name | Status | Address | Port | +-------------+---------+---------+------+ | lab-vesxi01 | running | :: | 6230 | | lab-vesxi02 | running | :: | 6231 | +-------------+---------+---------+------+
-
To view configuration information for a specific virtual BMC:
$ vsbmc show lab-vesxi01 +-------------------+---------------------+ | Property | Value | +-------------------+---------------------+ | active | False | | address | :: | | password | *** | | port | 6230 | | status | running | | username | admin | | viserver | 192.168.0.1 | | viserver_password | *** | | viserver_username | vsbmc@vsphere.local | | vm_name | lab-vesxi01 | | vm_uuid | None | +-------------------+---------------------+
-
Stopping the virtual BMC:
vsbmc stop lab-vesxi01 vsbmc stop lab-vesxi02
Once the virtual BMC for a specific VM has been created and started you can then issue IPMI commands against the address and port of that virtual BMC to control the VM.
In this example, if your VirtualBMC host has 192.168.0.100, you can control:
lab-vesxi01through192.168.0.100:6230lab-vesxi02through192.168.0.100:6231
by using IPMI. For example:
-
To power on the virtual machine
lab-vesxi01:$ ipmitool -I lanplus -H 192.168.0.100 -p 6230 -U admin -P password chassis power on Chassis Power Control: Up/On
-
To check its power status:
$ ipmitool -I lanplus -H 192.168.0.100 -p 6230 -U admin -P password chassis power status Chassis Power is on
-
To shutdown
lab-vesxi01:$ ipmitool -I lanplus -H 192.168.0.100 -p 6230 -U admin -P password chassis power soft Chassis Power Control: Soft
-
To reset the
lab-vesxi02:$ ipmitool -I lanplus -H 192.168.0.100 -p 6231 -U admin -P password chassis power reset Chassis Power Control: Reset
Both vsbmcd and vsbmc can make use of an optional configuration file, which is looked for in the following locations (in this order):
VBMC4VSPHERE_CONFIGenvironment variable pointing to a file$HOME/.vsbmc/vbmc4vsphere.conffile/etc/vbmc4vsphere/vbmc4vsphere.conffile
If no configuration file has been found, the internal defaults apply.
The configuration files are not created automatically unless you create them manually. And even if you don't create a configuration file, it won't matter in most cases.
Below is a sample of vbmc4vsphere.conf.
[default]
#show_passwords = false
config_dir = /home/vsbmc/.vsbmc
#pid_file = /home/vsbmc/.vsbmc/master.pid
#server_port = 50891
#server_response_timeout = 5000
#server_spawn_wait = 3000
[log]
# logfile = /home/vsbmc/.vsbmc/log/vbmc4vsphere.log
debug = true
[ipmi]
session_timeout = 10Once you invoke vsbmc add command, everything that you specified will be stored as config file per virtual machine under $HOME/.vsbmc/ by default. There files can be used backup/restoration, migration, and of course can be managed by any kind of configuration management tools. Please note everything including password stored in plain text in these config file.
The path for these files can be changed by config_dir in your vbmc4vsphere.conf described above.
$ cat ~/.vsbmc/lab-vesxi01/config

username = admin
password = password

viserver = 192.168.0.1

viserver_password = my-secure-password

vsbmc add lab-vesxi01 \
--vm-uuid 903a0dfb-68d1-4d2e-9674-10e353a733ca \
--port 6230 \
--viserver 192.168.0.1 \
--viserver-username vsbmc@vsphere.local \
--viserver-password my-secure-passwordThe UUID for virtual machines can be gathered in various ways like govc and PowerCLI.
# Get UUID by govc
$ govc vm.info lab-vesxi01

903a0dfb-68d1-4d2e-9674-10e353a733caIn the vCenter Server, by using VirtualBMC for vSphere (0.0.3 or later), you can enable the vSphere DPM: Distributed Power Management feature for Nested-ESXi host that is running in your VMware vSphere environment.
So you can achieve:
- Power-On the virtual ESXi in the same way as for physical ESXi.
- Automated power on/off control of ESXi hosts based on the load of the host cluster by vCenter Server.
See 📖the guide on GitHub Wiki page to use with Nested-ESXi and vCenter Server.
In the oVirt, by using VirtualBMC for vSphere, you can enable the Power Management feature for Nested-KVM that is running in your vSphere environment.
See 📖the guide on GitHub Wiki page to use with Nested-KVM and oVirt.
With VirtualBMC for vSphere, you can control your virtual machines in the same way as a physical server. This means that tasks that require a physical BMC can be done in a virtual environment.
One such example is the provisioning of a physical server.
Here's how to automatically provision OpenShift to a physical server, called Bare Metal IPI, using a virtual machine in vSphere environment with VirtualBMC for vSphere.
See 📖the guide to GitHub Wiki page to use with OpenShift Bare Metal IPI.
This project is started based on the copy of VirtualBMC 2.1.0.dev and customized to support the VMware vSphere environment instead of the OpenStack.
