[one.vm.updateconf] Invalid RAW section: cannot validate DATA with domain.rng schema

TiDjY35 · August 20, 2021, 10:49am

Hello,

I have this error when I want to map a usb key in my VM

my config file for update

I use

OpenNebula 6.0.0.2 on Ubuntu 18.04
libvirtd (libvirt) 4.0.0

I modified the files as shown here but without success

github.com/OpenNebula/one

The VM RAW data can't have several <devices /> entries

**Description** We upgraded our OpenNebula to 5.12.1 successfully (with minor… documentation issues [#4998](https://github.com/OpenNebula/one/issues/4998) and [#4999](https://github.com/OpenNebula/one/issues/4999)). There is a regression in the hanling of `RAW` data. We build some template with several devices `RAW` data like: ``` RAW=[ DATA=" <devices> <controller type='scsi' index='0' model='virtio-scsi'> <driver queues='2'/> </controller> </devices> <devices> <video> <model type='vga' vram='16384' heads='1'/> </video> </devices>", TYPE="kvm" ] ``` it was working fine with `5.10.1` but fails with `5.12`: ``` Mon Jul 27 12:14:24 2020 [Z0][ONE][E]: Invalid RAW section: cannot validate DATA with domain.rng schema Mon Jul 27 12:14:24 2020 [Z0][ReM][E]: Req:2304 UID:4 one.vm.allocate result FAILURE [one.vm.allocate] Invalid RAW section: cannot validate DATA with domain.rng schema ``` When I remove one `<devices />` element, it's working. Having several `<devices />` entries is not a problem for `libvirt` since OpenNebula generate itself `deployment.0` files containing several ones: ``` xml <domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'> <name>one-388035</name> <title>etb1.horus</title> <vcpu><![CDATA[4]]></vcpu> <cputune> <shares>205</shares> </cputune> <memory>3145728</memory> <os> <type arch='x86_64'>hvm</type> </os> <devices> <emulator><![CDATA[/usr/bin/qemu-system-x86_64]]></emulator> <disk type='file' device='disk'> <source file='/var/lib/one//datastores/0/388035/disk.0'/> <target dev='sda'/> <boot order='1'/> <driver name='qemu' type='qcow2' cache='none' discard='unmap'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <disk type='file' device='disk'> <source file='/var/lib/one//datastores/0/388035/disk.1'/> <target dev='sdb'/> <driver name='qemu' type='qcow2' cache='none' discard='unmap'/> <address type='drive' controller='0' bus='0' target='1' unit='0'/> </disk> <disk type='file' device='cdrom'> <source file='/var/lib/one//datastores/0/388035/disk.2'/> <target dev='hda' bus='ide'/> <readonly/> <driver name='qemu' type='raw'/> </disk> <interface type='bridge'> <virtualport type='openvswitch'/> <source bridge='nebula'/> <mac address='02:00:0a:01:01:65'/> <target dev='one-388035-0'/> <model type='virtio'/> </interface> <graphics type='vnc' listen='vnc.localdomain' port='36125' keymap='fr'/> <input type='tablet' bus='usb'/> </devices> <features> <acpi/> </features> <devices> <controller type='scsi' index='0' model='virtio-scsi'> <driver queues='2'/> </controller> </devices> </domain> ``` **To Reproduce** Create a template with the following `RAW` data: ``` RAW=[ DATA=" <devices> <controller type='scsi' index='0' model='virtio-scsi'> <driver queues='2'/> </controller> </devices> <devices> <video> <model type='vga' vram='16384' heads='1'/> </video> </devices>", TYPE="kvm" ] ``` **Expected behavior** The template should be created. **Details** - Affected Component: oned - Hypervisor: KVM - Version: 5.12.1 **Additional context** I have a patch and I'll make a pull request. ## Progress Status - [ ] Branch created - [ ] Code committed to development branch - [ ] Testing - QA - [ ] Documentation - [ ] Release notes - resolved issues, compatibility, known issues - [ ] Code committed to upstream release/hotfix branches - [ ] Documentation committed to upstream release/hotfix branches

Hi @TiDjY35,

Please make sure your raw section can be validated against the libvirt schema that you can find in /usr/share/one/schemas/libvirt/domaincommon.rng.

Cheers.

Hi @rdiaz

How to do this ?

Thanks

rdiaz · August 25, 2021, 7:07pm

Please try with: <devices><hostdev mode='subsystem' type='usb'><source><vendor id='0x1cf1'/><product id='0x0030'/></source></hostdev></devices>

Note that in the screenshot you sent there is no space between product and id.

Hope this helps.

I could have damaged my eyes for a long time before seeing this. I have made a copy / paste of the return provided by the DMESG.

it works with ZeroorMore modification in /usr/share/one/schemas/libvirt/domaincommon.rng

Merci @rdiaz
