I am running a number of KVM guests on a physical machine, and want

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.
