Backup virtual machines with Vmware consolidated Backup

To backup entire virtual machine while are running, you have to use the VBC provided by vmware.
this is a commandline tool that speaks with your VirtualCenter and tell it to create a Snapshot of a virtual machine, then detach it and copy the vmdk files to a location.

Take a look here http://www.vmware.com/products/vi/consolidated_backup.html to understand how it work.

the sintax of the command is like this:

vcbmounter.exe -m nbd -h yourvitualcenter.yourdomain -u username -p password -a name:VMname -t fullvm -r pathwheretosave

With "-m nbd" you can backup your Vm through an ethernet instead of a FibreChannel SAN connection.

Phisical 2 Virtual of RedHat 9.0 kernel 2.4 smp

I've made this on a RedHat 8.0 machine... maybe you can find this useful.

This phisical machine is an IBM X series 235 with a RAID 5 server raid controller running  RedHat linux 8.0 kernel 2.4.20-8smp.

I've used the Vmware converter standalone on  my Debian Squeeze laptop to "hot import" this machine.

Unfortunately this tool can't syncrhonize data between phisical and new virtual machine, so before start the migration I had to stop Lotus Domino server to have all databases updated on the virtual machine.

The migration was completed succesfully, and I've powered on my virtual machine but the first problem is here:

A terrible message appear instead of Grub boot menu:

"Cannot load Operating System"

Thinking about.....

Ok, grub is not installed in the MBR; so I've attached a RedHat enterprise linux iso to the VM cdrom,  rebooted into a linux rescue mode; chrooted to the installation and installed grub with:

me@linuxbox#grub-install /dev/sda

then I ran kudzu daemon to remove all old devices configuration (2 broadcom network adapter) and to add new (buslogic SCSI adapter).

Next I've to change hostname and IP address; and install Vmware tools;
don't forget or skip this step, or you'll have a 10 Mbps Nic and you can receive this message in console:

eth0: RUNT packet!

Using Vmware webaccess under linux and Firefox 3

The only way to have a working vmware console under linux, is using "webaccess" or connecting via msRDP to a win client .

Let's start setting up webaccess plugin.

Open you r *zilla browser and point to http://yourvirtualcenter.yourdomain and don't worry about "usupported browser message"; I've made this under Iceweasel on Debian Squeeze.
Try to open a virtual machine's console; you'll be asked to install a plugin, but unfortuantely the plugin installation fails.

How to solve this problem...

Frist install libexpat library.
Under  Debian Squeeze (and all debian like distros):

  1. apt-get update
  2. apt-get install libexpat1
  3. ln -s /usr/lib/libexpat.so.1 /usr/lib/libexpat.so.0

Go another time to your virtualcenter webaccess and now you can install the pluging and open the console.
