Description Eric Blake 2012-09-07 00:40:08 EDT
Cloning to get libvirt to expose this.

+++ This bug was initially created as a clone of Bug #854191 +++

Description of problem:

There is a bug [1] (VM will reboot if no boot failed).

As said in [2], we need to add a new boot parameter and put it into romfile for seabios to use, it's used to configure the delay time.

This work should start on upstream.

[1] Bug 831273 - RFE: reboot VM if no bootable device found
[2] https://bugzilla.redhat.com/show_bug.cgi?id=831273#c18

--- Additional comment from akong@redhat.com on 2012-09-06 21:15:00 MDT ---

patch posted to upstream: http://patchwork.ozlabs.org/patch/182306/

 -boot reboot-timeout=10000

With this option, guest will wait for a given time if not find
bootabled device, then reboot. If reboot-timeout is '-1', guest
will not reboot, qemu passes '-1' to bios by default.

Hi Eric,

If customer wants to use this 'feature'[1], do we need to change libvirt/virt-manager/etc to use this qemu parameter?

    Add support for reboot-timeout

    qemu: Add support for reboot-timeout
Comment 7 zhpeng 2012-11-02 03:47:06 EDT
Test ENV:

Run a guest without any bootable device or pxe env.

Tried several rebootTimeout value: -1, 0, 1, 10000, 65535, >65535, <-1, 1.5, -1.5

    <type arch='x86_64' machine='rhel6.3.0'>hvm</type>
    <boot dev='network'/>
    <boot dev='hd'/>
    <bios useserial='yes' rebootTimeout='$TIME'/>

qemu process can get the correct value, and it works fine. 

0-65535, guest will reboot after 0~65s if boot from failure.
-1, will not reboot again.

when value is Out of range libvirt will report error:
virsh # edit aaa
error: unsupported configuration: invalid value for rebootTimeout, must be in range [-1,65535]
Failed. Try again? [y,n,f,?]:

So it's verified.
