From: Rohit Kumar <rohit.kumar3@xxxxxxxxxxx> This patch introduces the logic to format and parse remote NVRAM. Update NVRAM element schema, and docs for supporting network backed NVRAM. NVRAM backed over network would give the flexibility to start the VM on any host without having to worry about where to get the latest nvram image. <nvram type='network'> <source protocol='iscsi' name='iqn.2013-07.com.example:iscsi-nopool/0'> <host name='example.com' port='6000'/> </source> </nvram> or <nvram type='file'> <source file='/var/lib/libvirt/nvram/guest_VARS.fd'/> </nvram> In the qemu driver we will support the new definition only with qemu's supporting -blockdev.
