Description Robert Hoo 2018-01-29 07:23:34 UTC

Environment:
KVM/QEMU:qemu-kvm-rhev-2.10.0-17.el7
Base OS: RHEL7.5 BETA
Guest OS: RHEL7.5 BETA
Platform: SKL-2S



Steps to Reproduce:
1.Setup the AEP with 2-1-1 configuration on SKL-2S
2.Install RHEL7.5 BETA on SKL host
3.Replacing the KVM package with the version(qemu-kvm-rhev-2.10.0-17.el7.x86_64)
4.Check the pmem dev via command
[root@cr-rhel ~]# ll /dev/pmem*
brw-rw---- 1 root disk 259, 0 Jan 28 23:54 /dev/pmem4
brw-rw---- 1 root disk 259, 1 Jan 26 02:26 /dev/pmem5
5.Create the guest with "/dev/pmem4" as:
qemu-system-x86_64 -M q35,accel=kvm,nvdimm -smp 8 -cpu host -m 16G,slots=32,maxmem=96G -object memory-backend-file,id=mem1,share,mem-path=/dev/pmem4,size=16G -device nvdimm,memdev=mem1,id=nv1,label-size=128k -device virtio-net-pci,netdev=nic0,mac=52:52:00:66:92:66 -netdev bridge,id=nic0,br=virbr0,helper=/usr/libexec/qemu-bridge-helper -drive file=/opt/rhel7u5.qcow2,if=virtio,id=virtio-disk0,format=qcow2 -daemonize
6.Check the nvdimm device in guest and mount it to /mnt/:
[root@localhost ~]# ll /dev/pmem0
brw-rw----. 1 root disk 259, 0 Jan 29 11:03 /dev/pmem0
[root@localhost mnt]# mkfs.xfs /dev/pmem0
[root@localhost mnt]# mount /dev/pmem0 /mnt/
7.Download the nvml (git clone https://github.com/pmem/nvml)
8.Make nvml test as following:
cd /root/nvml; make; make install

Actual results:
The nvml tools make/make install successful

Expected results:
[root@localhost nvml]# make
src/common.inc:262: *** libndctl(version >= 58.2.37) is missing -- see README.  Stop.

Additional info:
[root@localhost nvml]# rpm -qa | grep ndctl-devel
ndctl-devel-58.2-3.el7.x86_64
[root@localhost nvml]# ndctl --version
58.2

How does it have anything to do with qemu-kvm-rhev ? IMHO, it is more about nvml.
Please correct me if I'm wrong. Thanks!

Yes you're right.
This is non business with qemu, just about the test tool itself compilation erros/environment requirements. 
We've solved it but some further test still fails, using nvml test tool. We're checking that now, will feed you back on progress. Thanks.

We have bug1365721 to track the nvml tests. Maybe we should update on that bz ?

Comment 5 Robert Hoo 2018-02-01 08:54:05 UTC

Yes, the issue we met as the same as bug1365721

Mark bug1539541 as duplicated and track the bug1365721.
