RE: [Xen-users] VM keeps rebooting when building via pxe

["Pinto, Melzer" <Melzer.Pinto@xxxxxxx>]

Hi Melody,
Thanks for your response.
I tried this again today and here is what I see. I am using Oracle VM manager 
to create the pxe configuration files. When I create the pxe configuration 
file, the following 2 files get created

diff -y vm.cfg vm.cfg.orig
bootargs = 'bridge=xenbr0,mac=00:16:3E:35:C7:95,type=netfront | bootargs = 
'bridge=xenbr0'
bootloader = '/usr/bin/pypxeboot'                               bootloader = 
'/usr/bin/pypxeboot'
disk = ['file:/var/ovs/mount/ADB5300DA0664B9C8CBDBAC34BFFC5A1   disk = 
['file:/var/ovs/mount/ADB5300DA0664B9C8CBDBAC34BFFC5A1
memory = 2048                                                   memory = 2048
name = '66_oraclevm3'                                         | name = 'PXE_pvm'
on_crash = 'restart'                                            on_crash = 
'restart'
on_reboot = 'restart'                                           on_reboot = 
'restart'
uuid = 'da985745-54ec-4387-8d3e-e80f2242b698'                 <
vcpus = 2                                                       vcpus = 2
vfb = ['type=vnc,vncunused=1,vnclisten=0.0.0.0,vncpasswd=ovsr   vfb = 
['type=vnc,vncunused=1,vnclisten=0.0.0.0,vncpasswd=ovsr
vif = ['bridge=xenbr0,mac=00:16:3E:35:C7:95,type=netfront']     vif = 
['bridge=xenbr0,mac=00:16:3E:35:C7:95,type=netfront']
vif_other_config = []                                           
vif_other_config = []

I edit the vm.cfg.orig file with the suggestion you made
on_crash="destroy"
on_reboot="destroy"

I then run a xm create on the vm.cfg file and it starts to pxe  and builds. 
When the build is completed it goes back to rebuilding the host again. I then 
edited the pypxeboot line to pygrub in vm.cfg but now it returns with a "Error: 
Boot loader didn't return any data!" error

Any thoughts on this and what needs to be changed in these steps?

Thanks
Melzer

You want
on_crash="destroy"
on_reboot="destroy"

instead of restart. Then, upon reboot, it will destroy the current VM.
You'd then used a running config that uses pygrub as your bootloaded
instead. This config would have

on_reboot="restart"
on_crash="restart"
