<title>RE: [CentOS-virt] how to enable auto-start on newer versions of Xen ?</title>

<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;">PJ,</span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;"></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;">I didn't have virsh installed (libvirt-client). After having installed it, it still didn't see the process:<br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;"><br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;">virsh autostart testvm<br />error: failed to connect to the hypervisor<br />error: no valid connection<br />error: Failed to connect socket to '/var/run/libvirt/libvirt-sock': No such file or directory<br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;"><br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;">Then, after having installed libvirt, it gives essentially the same error.<br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;"><br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;">I was thinking that in iterations past, it was possible just to run the hypervisor, put a symlink in /etc/xen/auto, and VMs would be auto-started upon reboot. Maybe I'm wrong, and maybe those older boxes had libvirt installed on them, too.<br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;"><br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;">If I need to install libvirt, what does this mean overall? What am I changing? What other process needs to run or be started upon boot on a CentOS 7.x box?<br /></span></p>

<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;"></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;">In days past, all I had to do was create /etc/xen/auto and put a symlink in there to the config file for each VM I wanted to have started automatically.<br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;"><br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;">Since updating to 4.6, this doesn't work. Period.<br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;"><br /></span></p>
<p style="padding: 0; margin: 0;"><span style="font-size: 10pt; font-family: tahoma,arial,helvetica,sans-serif;">I'm having a hard time finding what needs to change in order to get VMs to auto start on reboot of a server. Can someone please point me to documentation that I have missed or share the gold nugget?<br /></span></p>
