Re: [libvirt] [RFC] Power Hypervisor Libvirt support
Hello again,
I very am glad with all the feedback I got. The following attachtment is
the result of the work using all the suggestions the list made. I also
have a few comments over this new RFC. Here is a little Changelog:
* Now the URI is recognized as phyp://user@hmc/managed_system. To use
path component of the uri struct, I had to implement a little function
to strip out the first slash of the string, giving me only 'path',
instead of '/path'.
* I implemented the option --with-libssh and --with-phyp right according
to what Daniel Berrange suggested.
* Now all the variable-size string buffers are manipulated with the
internal API virBuffer* to make it safer.
|
+- This made me think and change the __inner_exec_command function. Now
it returns char * with all the textual return, and I am passing int * as
reference to get the exit status - all the information I need about the
remote executed command.
|
+- And this also made me write a little auxiliar function to strip out
the '\n' from the textual return.
Known and unsolved issues:
* Authentication - need to improve the authenticantion as Daniel
Berrange said. Still in progress.
* Error codes.
* Logging and debugging messages.
Any comments are welcome,
[]'s

Hello all,
I've been working on a libvirt extension to manage IBM's Power VMs
(LPARs). The Power systems are managed through management console
referred to as the HMC or using a management partition (IVM). Both HMC
and IVM runs an SSH, then you can reach it via command line, and an HTTP
server, then you can reach it via web browser.
The protocol between the console and the partition (LPAR) is not
disclosed, therefore I propose the driver to execute commands remoetly
over an SSH connection to the consoles to manage IBM LPARs.
The patch attached is the first scratch of the driver that will interact
with HMC over a SSH connection. The URI model that is
used in virsh command line is:
virsh --conect phyp://$user@$server
Some known issues are:
* Next step is to make the URI like this: phyp://$user@
$HMC/@managed_system. Almost finished. What it takes now is
$server = $HMC = $managed_system.
* Next features in my TODO list are "resume", "stop" and
"reboot" the
LPAR.
Any comments are welcome.
Thanks,
