[et-mgmt-tools] Re: [libvirt] virt-install and custom distros

Can the issue be addressed in the upcoming virtinst release?

We have an application that builds custom distributions based on RHEL, CentOS or Fedora. We would like to install these over the network using virt-install, but we've run into an issue with the distro check logic. Specifically, virt-install fails unless it finds a string "Red Hat Enterprise Linux", "Fedora" or "CentOS" within the family field of the .treeinfo file.

Our application currently sets the family field to the user-provided distro name (see below). We have avoided using the base distro name given trademark concerns.

     family = <user provided value>
     variant = <user provided value>

We can get virt-install to pass the distro check by setting the family name to one of the accepted values, e.g.

     family = Fedora
     variant = [user provided distro name]

Is this the expected/desired use for the family and variant fields? Or is there another approach we should consider?


(cc-ing et-mgmt-tools, since that is the list for virt-install/

We shouldn't be failing if the family/variant is unknown: it's really
just a convenience check. We can just assume it's an unknown distro
and continue on, checking for [images-xen] and so on.. The code may
need to be reworked a bit to accomodate this.

Although we don't do it at the moment, I could see us in the future
using this family/variant value to check our internal db on whether
to set up virtio and other specific settings. So using custom values
here may not allow virt-install to choose an optimal config, but we
should still try and let the install proceed.
