Re: [libvirt] [PATCH v3] Add support for Veritas HyperScale (VxHS) block device protocol

Sample XML for a vxhs vdisk is as follows: <disk type='network' device='disk'> <driver name='qemu' type='raw' cache='none'/> <source protocol='vxhs' name='eb90327c-8302-4725-9e1b-4e85ed4dc251'> <host name='192.168.0.1' port='9999'/> </source> <backingStore/> <target dev='vda' bus='virtio'/> <serial>eb90327c-8302-4725-9e1b-4e85ed4dc251</serial> <alias name='virtio-disk0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </disk>

Signed-off-by: Ashish Mittal <Ashish.Mittal(a)veritas.com&gt; --- v2 changelog: (1) Added code for JSON parsing of a VxHS vdisk. (2) Added test case to verify JSON parsing. (3) Added missing switch-case checks for VIR_STORAGE_NET_PROTOCOL_VXHS. (4) Fixed line wrap in qemuxml2argv-disk-drive-network-vxhs.args. v3 changelog: (1) Implemented the modern syntax for VxHS disk specification. (2) Changed qemuxml2argvdata VxHS test case to verify the new syntax. (3) Added a negative test case to check failure when multiple hosts are specified for a VxHS disk. docs/formatdomain.html.in | 15 ++++- docs/schemas/domaincommon.rng | 1 + src/libxl/libxl_conf.c | 1 + src/qemu/qemu_command.c | 68 ++++++++++++++++++++++ src/qemu/qemu_driver.c | 3 + src/qemu/qemu_parse_command.c | 26 +++++++++ src/util/virstoragefile.c | 63 +++++++++++++++++++- src/util/virstoragefile.h | 1 + src/xenconfig/xen_xl.c | 1 + ...xml2argv-disk-drive-network-vxhs-multi-host.xml | 35 +++++++++++ .../qemuxml2argv-disk-drive-network-vxhs.args | 25 ++++++++ .../qemuxml2argv-disk-drive-network-vxhs.xml | 34 +++++++++++ tests/qemuxml2argvtest.c | 2 + tests/virstoragetest.c | 16 +++++ 14 files changed, 287 insertions(+), 4 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-drive-network-vxhs-multi-host.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-drive-network-vxhs.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-disk-drive-network-vxhs.xml
