I am running a number of KVM guests on a physical machine, and want to configure the hosts to boot from the network if the internal disk isn't bootable. After reading through a number of documents, I came across the following bug report:

https://bugzilla.redhat.com/show_bug.cgi?id=472236

According to that document (and the libvirt Domain XML format document), I should be able to configure two boot device statements by adding two boot tags to the domain configuration:

<os> <type arch='x86_64' machine='pc'>hvm</type> <boot dev='hd'/> <boot dev='network'/> </os>

When I attempt to start a guest with this configuration (I added the new line using virsh's edit command), I receive the following error:

virsh # start kvmnode2 libvir: QEMU error : internal error Failure while reading monitor startup output: Input/output error error: Failed to start domain kvmnode2

Pretty sure that's a KVM bug with it overflowing the available option ROM space. The XML syntax you have is correct for libvirt POV and works for me.
