Hi all,
I'm trying to get VM started with libiscsi (iSCSI initiator) device. Every
thing seems good from iSCSI point of view, but I'm stuck in VM boot,
"Booting from Hard Disk".
Any idea what can get wrong? how I can assure that the boot itself is from
the wanted disk.
Also will be helpful if
are pre-allocated and pre-registered,
hence in order to work with iSER from QEMU, one need to enable
MEMLOCK attribute in the VM to be large enough for all iSER buffers and RDMA
resources.

A new API to deploy zero-copy command submission. The new API takes I/O
vectors list and number of I/O vectors to submit as input parameters
when initiating the command. New API must be used if working with
iSER transport option.

New API is introduced in abstracion of the Libiscsi
zero-copy command submission. iSER is differing from TCP in
data-path, hence IO vectors must be transferred already when queueing
the PDU.

Actually I disagree with this suggestion. The new API could be used
also if iSER is not used, can
zero-copy command submission. iSER is differing from TCP in
data-path, hence IO vectors must be transferred already when queueing

to just upraise the maximum available pinnable-memory of
guest? without locking all 2G (in my guest)
because default maximum pinnable memory in QEMU is 60k.
Thank you all for your help,

Hi,
I have two questions,
First, I'm developing for Libiscsi and trying to work with virtio-scsi
dataplane or even virtio-blk dataplane and it doesn't works well.
I'm working with latest qemu and latest Libiscsi in RedHat 7 libvirt
package.
my iscsi xml part is :
virtio-blk -
15 matches
