Hi, if you look for a one-time boot off PXE, and then from hdd after installation finishes (which is the most frequent use case), you can use “Run Once” to override the “default” boot order. Instead of modifying the VM configuration twice. Nevertheless, the above should work, so I would start checking if the VM is indeed configured correctly (bug on ovirt side) or we create it ok but there’s a bug in lower layers (libvirt, qemu, ipxe). If you can check the VM in UI there is a “VM Devices” subtab new in 3.6 which can tell you if it even has a NIC attached; and there is the final libvirt domain xml being logged in /var/log/vdsm/vdsm.log when you launch the VM - there you can doublecheck the VM is started as expected Thanks, michal
Anyone have a hint?
Thanks,

boot_dev = params.Boot(dev='network') vm.os.set_boot([boot_dev]) vm.set_os(params.OperatingSystem(cmdline=kernel_cmd))
This line ^ is overwriting the complete OS configuration that you set before, so the change to the boot device is lost. If you enable the debug output of the SDK (with debug=True in the constructor of the API object) you will see that this is what is sent: <os> <cmdline>your command line</cmdline> </os> Try this instead: vm.set_os( params.OperatingSystem( boot=[ params.Boot(dev="network") ], cmdline=kernel_cmd ) ) It should result in sending this: <os> <boot dev="network"/> <cmdline>your command line</cmdline> </os> Not also that I believe that the kernel command line won't have any effect for the PXE boot, as it is used only for direct kernel boot.
vm.update()
