   I’m having a weird behavior. When I run rvc on one system, it always exits after executing one command. On another system, I get a new prompt and can enter new commands, even if I use the “-c command” option.

   I want the first behavior. Does anyone have any suggestions why the difference and what to do about it?

   Thankjs.

   Is this supported with vSphere 5? I tried to connect to my vSphere 5 VC and no love. I’m running ruby 1.9.2p290 on WinXP.

      The new RVC 1.6 works great in ESX/ESXi 4.x and 5.x for me.

      Wow I really like 1.6!

   are there any examples available of this? i’d like to be able to power off then unregister all of the vm’s in a datastore, and then register them in a new cluster. Is this something that could be done that way?

   Hello,

   I am trying to use rvc to revert a vm to a specific snapshots. I have no problem restoring VM to its current running snapshot; however, it seems that I can not revert to other snapshots for a given VM. Is is possible to do somethings like:

   ha-datacenter/vm> snapshot.revert vm_name snapshot_name

   Thanks!

   Reply ↓
7. Dominic November 21, 2011 at 1:08 pm

   My VM’s have two snapshots. Depending on the type of testing I am performing, I need to revert to a specific snapshot. I simply need do something like:

   ha-datacenter/vm> snapshot.revert vm-name snapshotname

   That command fails, of course, as “snapshot.revert” is only takes 1 arg: the name of the VM. Help and documentation indicates that “snapshot.revert” default to the current snapshot. How can I used rvc to revert to other snapshots besides the current running snapshot?

   Thanks!

   Thanks for a cool utility!
   I’m trying to use this against ESXi host to view a VM, but I get this error:

   /172.24.x.x/ha-datacenter/vm> v 1
   RestrictedVersion: fault.RestrictedVersion.summary

   After looking around, it seems like this error has something to do with licensing of ESX vs ESXi.
   Is it not possible to use this utility to view consoles of ESXi hosts?

      AFAIK only vSphere Client can be used with the free ESXi. The non-free ESXi works fine.

   We have ESX where I work and I’m using datastore.edit (“edit”) to alter the values of a .VMX file.

   The guest is powered off, of course.

   Sometimes, datastore.edit will handle the (un)registration, while other times, it will not.

   Can anybody help me with the entire process?

   Example:
   vm.off
   datastore.edit
   vm.unregister
   vm.register
   vm.on

   Thanks, in advance!

    Hi!

    Does anybody have an example of using the register command in RVC? I assume you have to connect through a host, not a datacenter.

    I always seem to get something like:
    /myhost> vm.register /my/path/to/myguest/myguest.vmx
    Expected Folder but got RbVmomi::VIM at “.”

    Thanks!

    1. Rich Lane July 27, 2011 at 10:23 am

       Specify the –folder option to pick which VM folder to add the VM to. You don’t need to connect directly to the host.

       1. Mike July 27, 2011 at 3:47 pm

          Thanks for the speedy reply! Actually, I think I now know a little more about the process, so may I re-ask my question a totally different way? :-)

          I have been having a real hard time editing VMX files and having them “stick.”

          As I now understand the process of Editing Guest Settings, if I want to edit a VMX file (at a low API level), I would do something like this:
          Power off the VM
          Download the VMX
          Edit the VMX
          Re-upload the VMX
          Unregister the VM / VMX / guest
          Register the VMX
          Power on the VM

          However, if I understand things better now, in RVC, we could simply do this:
          Power off the VM
          Edit the VMX from the *correct location* (edit implied download / “edit” / upload)
          Power on the VM (unregistering / registering should be automatic)

          …but the “correct location” is the key… The VMX file appears in many locations.

          We need the reference for the host’s VMX file, right? If so, the VMX at the host location can be discovered with basic.info (look for “host:” and navigate to the correct VMX file).

          If so, then it would be much easier:
          vm.off /{vcenter}/host/{datacenter}/{cluster}/hosts/{host}/vms/{guest}

          datastore.edit /{vcenter}/host/{datacenter}/{cluster}/hosts/{host}/vms/{guest}/files/{vmxfile}

          vm.on /{vcenter}/host/{datacenter}/{cluster}/hosts/{host}/vms/{guest}

          Then, it would handle all the (un)registering for you….

          Am I right in my assumptions or am I missing something?

          Thanks!!!

       SFL is “spawn-for-legacy”.

       SFL supports these Rubies:
       (On MacOS) MRI 1.8.6, 1.8.7, 1.9.1, 1.9.2-rc2
       (On UNIX) MRI 1.8.6, 1.8.7, 1.9.1, 1.9.2pre
       (On Windows) MRI 1.9.1, 1.9.2pre

       Unfortunately, SFL does not support these:
       MRI 1.8 on Windows
       Other Ruby implementations such as JRuby, Rubinius and MacRuby

       http://www.ruby-forum.com/topic/912179
       https://github.com/ujihisa/spawn-for-legacy

       In the little snippet, below, I used Process.spawn() and not just spawn().

       Oddly, on my Ubuntu Lucid 32 bit node and on my Lucid 64 bit node, both with MRI Ruby 1.8.7, I can use Kernel.spawn() but not plain old spawn(), so I chose Process.spawn() to avoid confusion.

       Try to install sfl:
       sudo gem install sfl

       Check your ruby version:
       ruby -v

       Then try it in irb:
       require ‘rubygems’
       require ‘sfl’
       spawn ‘ls’
       Process.spawn ‘ls’
       Kernel.spawn ‘ls’

       (You may have to provide full paths to commands you may run, like this:
       Process.spawn(‘/bin/ls’)

       Does it work on your mac?

    2. Mike April 26, 2011 at 8:20 am

       Oh, and Process.spawn() should already work for MacRuby, if I am reading this correctly:

    RVC is an awesome utility!!! :-)

    I do notice one issue, though. :-(

    On Ruby 1.8.7, the datastore.* commands, such as edit, download, and upload do not work, since spawn() is not implemented. It seems that Process.spawn() / Kernel.spawn() is a Ruby 1.9.x thing.

    How I fixed it:
    sudo gem install sfl
    Edited /usr/lib/ruby/gems/1.8/gems/rbvmomi-1.2.3/lib/rbvmomi/vim/Datastore.rb as follows:
    Added -
    require ‘sfl’
    Changed both ‘spawn’ entries, as follows -
    pid = spawn CURLBIN, “-k”, ‘–noproxy’, ‘*’, ‘-f’,
    -to-
    pid = Process.spawn CURLBIN, “-k”, ‘–noproxy’, ‘*’, ‘-f’,
