[libvirt-users] VMs do not start randomically during host boot

Hi Folks, Host: Ubuntu 10.04 64bits 3 Guests with Ubuntu 10.04 64bits Every monday, when I turn the host on, some guests starts automatically and others don´t. Every week libvirt "elects" a different guest and don´t start it. If I start it manually, it boot fine. Looking at /var/log/libvirtd, it only show the log of the guests that boot. Not a tip of the sleepy guests servers. Could somebody give me a glue on how to find the problem ? Thanks in advance, Josir.
