Error messages

[atwright147]

@RamyElkest a new issue I am having now, is that Libvirt is spitting out lovely useful messages into the terminal but I cannot seem to get them in JS.

Terminal output after an error:

libvirt: Domain Config error : operation failed: domain 'created_from_post' already exists with uuid d6bd24d8-ff09-426d-ae23-e8c3cdb696e6
Error: virDomainDefineXML() failed

I can only get: virDomainDefineXML() failed, but Domain Config error : operation failed: domain 'created_from_post' already exists with uuid d6bd24d8-ff09-426d-ae23-e8c3cdb696e6 would be way more useful to me :)

Is there something I am doing wrong, or could you make a change to expose these messages?

More info

This is where I am using it: https://gitlab.com/atwright147/kvm-controller/commit/d3667b39bdb7457020d01358923949d8464b33c2

Sending a payload like:

{
	"xmlString": "<domain type='kvm'><name>created_from_post</name><memory unit='MB'>512</memory><vcpu>1</vcpu><os><type arch='i686'>hvm</type></os><clock sync='localtime'/><devices><disk type='file' device='disk'><source file='/var/lib/libvirt/images/demo2.img'/><target dev='hda'/></disk><disk type='file' device='cdrom'><source file='/home/vagrant/Downloads/Core-current.iso'/><target dev='hdc'/><readonly/></disk><interface type='network'><source network='default'/></interface><graphics type='vnc' port='-1'/></devices></domain>"
}

@RamyElkest do you have any thoughts on this?
