[libvirt-users] Retry reboots in xmls files for libvirt
Hi, I have a virtual machine defined by xml that start from pxe (network boot), my problem is that sometimes the dhcp server is not ready when the virtual machine try to boot. I need that the virtual machine keep asking for dhcp (network reboot) many times, until dhcp is ready and can start the virtual machine with a valid ip. How can I configure that in the xml file?

I'm not sure you can configure that for ipxe or qemu, but you can set the reboot timeout for the machine in <os> tag like this: <bios rebootTimeout='0'/> that means immediate reboot when there is no place to boot from. In order for it not to boot from any other device or for any other details, see http://libvirt.org/formatdomain.html Have a nice day, Martin

Hi, I am not using quemu, i am using XEN, is there any option to allow me to do that? In the libvirt documentation specify that those options are only available on quemu. BR //Fernando 2014/1/16 Martin Kletzander <mkletzan@redhat.com>

I don't know whether xen knows how to do that or how to request any kind of this configuration, sorry. But if you fond how this is made for xen, it might be pretty easy to wire up in libvirt. Martin
