Hi I have a clearos(centos) server running directly on the hardware.

What is the best way of having it running on the xenserver with ha-lizard?

I have purchased second server ....
Thanks,

Are you referring to converting a physical server to a VM (as in P2V)? If so, there is nothing different that needs to be done when doing this in an HA-Lizard enviro. You should be able to find several P2V procedures for linux machines with a web search.

If you are intending to use your existing server as one of the hosts in the HA-Lizard cluster, then I would suggest the following:

- Install XenServer onto your new server.
- Run our noSAN installer on top of the new XenServer install (following all the prerequisite instructions)

Once done - use whatever method you want to move the bare metal linux machine to a VM on the new XenServer.
Before proceeding - Backup your data

With the machine successfully moved - installer XenServer onto the second host and then join it to the pool. Run the noSAN installer on the second host.

When the installer compeletes the storage will automatically start syncing between the hosts.

Thanks,
Actually I have not found anything solid on p2v conversion from linux. The only thing I found was using the clonezilla.
Though it seems to have some limitations which may not work for me.

Hi,
I am trying to install this on a single server but I am not able to add pool with only one server available. Can I continue installing ha-lizard and when second server is available create the pool and add both servers to it?
Thanks

Hi,
I have tried to run the installer on the single server but it fails with an error: Installer requires a pool with 2 hosts. Exiting..

Any idea how to fix it?
Any work around?

Thank you.

Sorry about that. I forgot that the script validates for exactly 2 servers in the pool.
Comment out the following lines in the script to get past the validation. If you are not comfortable making the changes, let me know via the forum so I can provide an updated installer.
