Libvirt domain XML allows only local filepaths to specify a loader element or its matching NVRAM. Given that VMs may themselves move across hypervisor hosts, it should be possible to allocate loaders/NVRAM disks on network storage for uninterrupted access. This series extends the loader & NVRAM disk elements to be described as virStorageSource* elements, as discussed in : https://www.redhat.com/archives/libvir-list/2018-March/msg01721.html Sample XML with new annotation: <loader readonly='yes' type='pflash' backing='file'> <source file='/usr/share/OVMF/OVMF_CODE.fd'/> </loader> <nvram backing='network'> <source protocol='iscsi' name='iqn.2013-07.com.example:iscsi-nopool/0'> <host name='example.com' port='6000'/> </source> </nvram> References: ---------- v0/ Proposal: https://www.redhat.com/archives/libvir-list/2018-March/msg01721.html.v1 v1: https://www.redhat.com/archives/libvir-list/2018-April/msg02024.html v2: https://www.redhat.com/archives/libvir-list/2018-May/msg00948.html Changelog: --------- Changes since v2: - Consolidated patches with related data structures to avoid build breakage. - Passes make check & make syntax-check. Prerna Saxena (4): Schema: Introduce XML schema for network-backed loader and nvram elements. Loader: Add a more elaborate definition. Test: Add a test snippet to evaluate command line generation for loader/nvram specified via virStorageSource Documentation: Add a blurb for the newly added XML snippets for loader and nvram. docs/formatdomain.html.in | 36 +++- docs/schemas/domaincommon.rng | 108 +++++++++-- src/bhyve/bhyve_command.c | 6 +- src/conf/domain_conf.c | 250 +++++++++++++++++++++++-- src/conf/domain_conf.h | 11 +- src/qemu/qemu_cgroup.c | 13 +- src/qemu/qemu_command.c | 21 ++- src/qemu/qemu_domain.c | 31 ++- src/qemu/qemu_driver.c | 7 +- src/qemu/qemu_parse_command.c | 30 ++- src/qemu/qemu_process.c | 54 ++++-- src/security/security_dac.c | 6 +- src/security/security_selinux.c | 6 +- src/security/virt-aa-helper.c | 14 +- src/vbox/vbox_common.c | 11 +- src/xenapi/xenapi_driver.c | 4 +- src/xenconfig/xen_sxpr.c | 19 +- src/xenconfig/xen_xm.c | 9 +- tests/qemuxml2argvdata/bios-nvram-network.args | 31 +++ tests/qemuxml2argvdata/bios-nvram-network.xml | 42 +++++ tests/qemuxml2argvtest.c | 1 + 21 files changed, 606 insertions(+), 104 deletions(-) create mode 100644 tests/qemuxml2argvdata/bios-nvram-network.args create mode 100644 tests/qemuxml2argvdata/bios-nvram-network.xml -- 1.8.1.2 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
