CentOS virt - Aug 2016 - how to enable auto-start on newer versions of Xen ?

Hello,


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.



Since updating to 4.6, this doesn't work.? Period.



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?

Since you're speaking of upgrading, I assume you're using CentOS 6?
What version of the xen packages are you using?

There's a bug in the upstream 4.6 xendomains scripts (which start
things from /etc/xen/auto) when they run on RHEL-based systems.  That
should have been fixed in the xen-4.6.1-9 Virt SIG package.

Craig,

Try this:

mkdir -p /etc/libvirt/libxl/autostart
cd /etc/libvirt/libxl/autostart
ln -s /etc/libvirt/libxl/[name-of-vm].xml

I just verified that worked for me...  Here is my setup:

[root at host-1 ~]# ls -latr /etc/libvirt/libxl
total 24
drwx------. 6 root root 4096 Jun 26 15:31 ..
-rw-------  1 root root 1279 Jul 19 12:36 pulp.xml
-rw-------  1 root root 1279 Aug  1 12:38 solr.xml
-rw-------  1 root root 1300 Aug  4 13:01 workstation.xml
-rw-------  1 root root 1306 Aug  8 12:48 atomic-master.xml
-rw-------  1 root root 1271 Aug  8 12:48 db.xml
drwxr-xr-x  3 root root  111 Aug 16 12:12 .
drwxr-xr-x  2 root root   28 Aug 16 12:12 autostart
[root at host-1 ~]#
[root at host-1 ~]# ls -latr /etc/libvirt/libxl/autostart/
total 0
drwxr-xr-x 3 root root 111 Aug 16 12:12 ..
lrwxrwxrwx 1 root root  34 Aug 16 12:12 workstation.xml -> 
/etc/libvirt/libxl/workstation.xml
drwxr-xr-x 2 root root  28 Aug 16 12:12 .


Hope that helps!
