Last modified: 2013-02-21 02:23:16 EST
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/ example: -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. --- Additional comment from akong@redhat.com on 2012-09-06 22:33:32 MDT --- Hi Eric, If customer wants to use this 'feature'[1], do we need to change libvirt/virt-manager/etc to use this qemu parameter? [1] Bug 831273 - RFE: reboot VM if no bootable device found Thanks, Amos
Moving to POST: commit c33a922faad1de363aa4212edc1a329bd47e52b0 Author: Martin Kletzander <mkletzan@redhat.com> Date: Tue Sep 18 12:30:52 2012 +0200 Add support for reboot-timeout commit 94827a785d97e2ec83d488d664d10b28fbaed57e Author: Martin Kletzander <mkletzan@redhat.com> Date: Tue Sep 18 12:31:30 2012 +0200 qemu: Add support for reboot-timeout
Test ENV: libvirt-0.10.2-6.el6.x86_64 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 <os> <type arch='x86_64' machine='rhel6.3.0'>hvm</type> <loader>/usr/share/seabios/bios-pm.bin</loader> <boot dev='network'/> <boot dev='hd'/> <bios useserial='yes' rebootTimeout='$TIME'/> </os> 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.
