Ovirt devel - Apr 2010 - RFC: Advanced Storage Configuration

Hello,

I'd like to put forward the following proposal for your appreciation, in
order to add flexibility to the node configuration, so one can choose to
store guest's images in a different device than the core
OS/config/log/data today.

In essence, proposal involves the following:

- Addition of a new top level install menu called "Advanced Storage
Configuration" where one can select a storage device to which should the
guest's images be stored.
- Next to the device selection, creates a new volume group -
HostVG-Images - to be mounted at /images
- Perform adjustments do /var/lib/libvirt/images "mount binds"
against /images 

Comments ?

Regards,

This sound good, I would just like to extend this and allow also
separation of swap LV into separate VG.
It also makes sense to organize all of these option as a sub-menu
under storage configuration.
One more aspect is to extend the syntax of "storage_vol" boot
parameter to support autoinstalls with advanced storage
configurations:

 storage_vol=<DISK>,<VG>,<LV>,<SIZE_MB>:...

instead of current format:
storage_vol=BOOT_MB:SWAP_MB:ROOT_MB:CONFIG_MB:LOGGING_MB:DATA_MB

Any other ideas what else should we have in the storage configuration sub-menu?
