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 Has anyone bumped into this? I checked the KVM, libvirt and fedora ML archives, but wasn't able to locate a solution to this. I am using Fedora 10 with the latest updates. Thanks for any insight, - Ryan
