Autostart VM on boot

[Marcel Damásio]

Hi,

I'm using Fedora 8 as DOM0.
I created my virtual machines using virt-install.
Now I want to configure them to autostart on DOM0's boot, but I can't.

I tried a lot of solutions, but none worked.

Could somebody help me?

[David Levinger]

Creating a symlink in /etc/xen/auto that points to the config file of the
machine I want to autostart has worked for me in Fedora 8.

IE I store my config files in /etc/xen

ln –s /etc/xen/MachineFile /etc/xen/auto/MachineFile

Next time I boot the virtual machine starts right up.

Ok, but I used virt-install to create the VMs, so I don't have a config
file.

Trying this solution I found the config files at /var/lib/xend/domains/, all
generated by virt-install automatic.

So I created a symlink in /etc/xen/auto, but this didn't work.

Any other ideas?

Could you send me an example of config file machine that works for testing?
I don't know how to create a VM from one.

I use virt-install to install my vm’s as well, but when I used
virt-manager (to install) I ran into that other directory path that you
mentioned.

To install a para-virt example with virt-install I use something like the
following:

virt-install --bridge=xenbr0 --name=machinename --ram=1024 --vcpus=1
--file=/dev/vgmachine/lvmachine --paravirt
--location=http://1.1.1.1/pathto/ks -x "ks=http://1.1.1.1/config.cfg"
--vnc

Below is an example of a Windows VM that I have that is stored in /etc/xen
and worked just fine with the symlink method. If you’d like a linux
example or a para-virt example just let me know.

name = "MachineName"

uuid = "f771623c-acbe-18df-d3a9-e71246c88f2e"

maxmem = 1024

memory = 1024

vcpus = 2

builder = "hvm"

kernel = "/usr/lib/xen/boot/hvmloader"

boot = "c"

pae = 1

acpi = 1

apic = 1

on_poweroff = "destroy"

on_reboot = "restart"

on_crash = "restart"

device_model = "/usr/lib64/xen/bin/qemu-dm"

sdl = 0

vnc = 1

vncunused = 1

disk = [ "phy:/dev/vgcomp/lvmachine,hda,w",
"file:/root/bartpe.iso,hdb:cdrom,r" ]

vif = [ "mac=00:00:00:00:00:00,bridge=eth0,type=ioemu" ]

serial = "pty"

Hmmm,
Does that mean you have to have a config file in two different formats if you are using virsh?

I configure/build my xen domains using virsh. Do I then need an xm compatible file too to have a vm startup? I'm sure not... if I recall correctly if you create a domain via the gui it starts automatically after boot and that only have xml config files but not sure how to "simulate" that if you create the domains using custom xml config files.

Regards

Hi,

If the guest is created by libvirt (ie virt-install etc.), then I suggest
usign virsh to trigger autostarting. Here's what can be done:

emre@xenroot:~$ virsh
Connecting to uri: qemu:///system
Welcome to virsh, the virtualization interactive terminal.

Type:  'help' for help with commands
       'quit' to quit

virsh # list --all
 Id Name                 State
----------------------------------
  1 Pardus-PV            running
  - Pardus-2008          shut off

virsh # help autostart
  NAME
    autostart - autostart a domain

SYNOPSIS
    autostart [--disable] <domain>

DESCRIPTION
    Configure a domain to be automatically started at boot.

OPTIONS
    <domain>         domain name, id or uuid
    --disable        disable autostarting

virsh #

This system is running KVM, but it would be the same for XEN. try it out and
let us know :)

At least for me (Fedora 8) this does not work with Xen:

virsh # autostart server3
libvir: error : this function is not supported by the hypervisor: 
virDomainSetAutostart
error: Failed to mark domain server3 as autostarted

I guess I should grab some more time and convert my Xen build machines to KVM.

Autostarting xen VM's via libvirt isn't supported in the version in F-8, but
it is supported upstream as of about a month ago. You can try building from
upstream or wait for a new release to be cut, at which point it may be 
backported to f-8.

Marcel:

Do you have domain definitions in:

/var/lib/xend/domains

Shutdown the xend.

Edit

/var/lib/xend/domains/<UUID>/config.sxp

Add these two lines to the domain definition:

(on_xend_start start)
     (on_xend_stop shutdown)

Make sure that "xend" and "xendomains" start automatically in your "init.d".

By the way, I also have these actions in my config.sxp and can't 
remember if these were the default values after virt-install or not.

(actions_after_crash restart)
     (actions_after_shutdown destroy)
     (actions_after_reboot restart)

Let me know how it goes for you.

Good luck,
Aaron

[Marcel Damásio]

Hi Aaron,

Thanks a lot for helping me. It worked.

I added into *'/var/lib/xend/domains/<UUID>**/config.sxp'  *these lines:

*   (on_xend_start start)
   (on_xend_stop shutdown)*

Now, the VMs are really auto starting and shutting down!

Thanks for helping me.
