Hi Everyone,
I'd like to propose a feature we've been doing some investigation
into, which is to integrate cloud-init support into oVirt.
Cloud-init is used to help provision new Linux systems by setting
the hostname, ip, ssh keys, timezone, injecting files, and more.
It's used by OpenStack (amongst others) now, and has a lot of
features that may be helpful to our users.
Details are still evolving, but for more info please see the wiki page:
http://www.ovirt.org/Features/Cloud-Init_Integration
All feedback is welcome!
All feedback? Even if it's 3 months too late?
If so, then here's a few comments:
1. oVirt-3.2 completely supports IPv6 within guests. It would be nice to
carry this on to cloud-init, by allowing to set the IPv6 address of
the guest. (or are we happy with the auto configured ipv6 addresses?)
2. I think that the GUI used for setting IP addresses should be
immitated here. It allows Static/DHCP/None, and disables the
irrelvant fields when DHCP/None is selected.
3. Is "Support custom volume label for vm payloads" still on the TODO
list? Note: F19's dosfstools has renamed mkfs.msdos to mkfs.fat.
This means that creating a virtual floppy with a payload currently
does not work there (it's a tiny fix, for sure).
4. I do not see ovirt-guest-agent mentioned in the feaure page. It is
the obvious channel to report that cloud-init is Done to Engine.
5. When we come to implement auto-generate of system ssh key, we may
want to install a virtio-rng device in our VMs, to ensure that the
keys are not too easy to guess. (or create the key in the host and
inject it to the guest)
