[Fedora-xen] Autostart VM on boot

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.

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= -x "ks=" --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"

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.

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.

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?
