Title: SME 7 as a XEN PV DomU
Post by: ASPerience on September 30, 2009, 10:21:01 AM: Hi there.
I don't know if I am posting in the right category. If not, tell me where it is supposed to be.

I'm currently trying to use SME as a XEN PV DomU. And as it seems to be now working quite well, I'd like to share my experience with you.

I created an how-to (http://blog.webotin.fr/2009/09/sme-server-as-a-pv-xen-domu/), and would like to get feedbacks abou it.

If there is people interested in it, it can be re-used on contribs.org.

Regards,

I have not read it but it would be nice if you could add it to the wiki (as well).

interesting.. I would add only this.. when you say

Because SME detects xvc0 as the main terminal, I had to replace the last line of /etc/e-smith/templates/etc/inittab/90serial with :

$OUT .= "s$1:123457:respawn:/sbin/agetty hvc0 $device $terminal";

I suggest you to create a fragment in /templates-custom tree instead of editing original files.. in this way your configuration will survive a major upgrade

that said, IMHO it's worth to be in the wiki as virtualization is becoming a must nowadays

Ciao

I plan to add this how-to to the contribs.org wiki once all remaining issues are addressed.

I corrected the hvc0 application method using templates-custom.

Changing the console isn't necessary, what made you think the change was needed?

If I keep the console as it is by default, I don't get any prompt when uising xm console.
Maybe an issue related to XEN 3.2.

Can anyone confirm it's working out of the box with xen 3.2 ?

EDIT : I tried setting back console to xvc0. I confirm it's not working. Console display stops after HAL start. No login prompt is displayed.

Strange... my dom0 systems (CentOS based) do show a prompt out of the box when I access a xm console for the guests.

But CentOS uses xen 3.0, and console handling changed between 3.0 and 3.2.

That might be the cause then, but perhaps CentOS/Redhat has backported the feature, do you have a bug id referencing this change?

If you can provide details and possible help then we might be able to updated the templates to use the correct console device so this custom template isn't needed at all.
