[libvirt] [PATCH 0/9] qemu: Introduce support for new the block_set_io_throttle parameters add in the version 1.7 of qemu.
12:32 p.m.
This series of patches add suport for bps_max, bps_rd_max, bps_wr_max,
bps_max, bps_rd_max, bps_wr_max, and iops_size in the functions qemuDomainSetBlockIoTune,
and qemuDomainGetBlockIoTune.
The last patch add suport for therse parameters to the virsh blkdeviotune commande.
Matthias Gatto (9):
qemu: Add defines for the new throttle options
qemu: Add new throttle options to the structure
_virDomainBlockIoTuneInfo.
qemu: Add the capabilitie to detect if the qemu binary have the
capability to use bps_max and friends
qemu: Add bps_max and friends qemu driver
qemu: Add bps_max and friend to domain_conf
qemu: Add bps_max and friends QMP suport
qemu: Add bps_max and friends "text" suport
qemu: add bps_max and friends to qemu command genaration
qemu: Add bps_max and friends to virsh

New subject: [libvirt] [PATCH 2/9] qemu: Add new throttle options to the structure _virDomainBlockIoTuneInfo.
Modify the structure _virDomainBlockIoTuneInfo to suport total_bytes_sec_max,
write_bytes_sec_max,
read_bytes_sec_max, total_iops_sec_max, write_iops_sec_max, read_iops_sec_max,
size_iops_sec options.
Add the bool suport_max_options in the sturture _virDomainBlockIoTuneInfo used to know
if the qemu binary suport the bps_max options and they friends.
Change the initialisation of the variable expectedInfo in the test file
qemumonitorjsontest.c
to avoid compilling problem.
