VM oops while testing SPDK hotplug.sh

by Isaac Otsiabah

Daniel. I have done more testing using hotplug.sh and here is why one does not see the problem by running hotplug.sh as is. When hotplug.sh is run, it always creates a new VM to run the test on and, destroys the VM when completed. Therefore, it uses a fresh VM all the time and never gets the chance to do the inserts and remove on a VM that has run the same test several times (ie. 4 to 5 times) before. When I run hotplug.sh with a fresh VM, it passes, On the other hand, when I use the same VM that has run the test several times before, the VM oops, this is the problem. I also think this is the likely scenario the customer will experience. I wasn't clear in my earlier emails because i was still determining the cause of the problem (at the higher level at least). I think you will see the problem if you do this i. In an xterm window, Create the VM separately (without the -daemon flag). for example IMAGE=/home/fedora24/fedora24-2.img qemu-img create -f qcow2 $IMAGE 50G MEM=8192M FEDORA_ISO=/tmp/Fedora-Server-dvd-x86_64-24-1.2.iso qemu_pidfile=/tmp/qemu_pidfile qemu-2.7.1/x86_64-softmmu/qemu-system-x86_64 \ -hda $IMAGE \ -net user,hostfwd=tcp::10022-:22 \ -net nic \ -cpu host \ -m ${MEM} \ -pidfile "/tmp/qemu_pidfile" \ --enable-kvm \ -chardev socket,id=mon0,host=localhost,port=4444,ipv4,server,nowait \ -mon chardev=mon0,mode=readline \ -cdrom $FEDORA_ISO ii. Then comment out in hotplug.sh the portion that creates the VM. iii. Also comment out these 4 lines at the bottom in hotplug.sh to avoid killing the VM. qemupid=`cat "$qemu_pidfile" | awk '{printf $0}'` kill -9 $qemupid rm "$qemu_pidfile" rm "$test_img" iv.

We haven't hit the -net/--netdev issue that you mentioned yet because the version of qemu we are using is older (the current host system running this test is Fedora 25 with qemu 2.7.1). It looks like we'll need to update the script for that. We would be happy to accept a patch to hotplug.sh if the --netdev option also works on older qemu.

However, qemu-system-x86_64 version 2.9 does not have this option but it has -netdev option but is is different.

I installed sshpass and tested this -netdev flag redirection with a simple sshpass command to the vm but got no response. Therefore, i bypassed executing scripts/setup.sh and the hotplug binary using sshpass command. So I can test it without executing setup.sh and the hotplug binary through sshpass on port 10022.

VM oops while testing SPDK hotplug.sh

by Isaac Otsiabah

Hi Daniel, how are you? Daniel i performed two types of hotplug test using Fedora 25 (kernel 4.8.6-300, VM and host running the same kernel version). 1. Test 1 (Running hotplug.sh in once in a new VM): I created a Fedora25 image for the VM and used it to test hotplug.sh with no modification and it worked fine. With no modification, hotplug.sh performs the test on a newly installed VM every time and destroys the VM at the end. While this is ok, i think we should also run the test in an environment where the VM continue to run while NVMe hotplug operation is performed several times. This is a practical scenario at the customer environment so I tried to test it in Test 2 below. 2. Test 2 (Running hotplug.sh several times while VM continue to run): I created this small script to start the VM (Fedora25) on a Fedora 25 host, kernel-4.8.6. I commented out the portion that creates and destroys the VM in hotplug.sh so that the VM will keep running after a hotplug.sh run. [root@localhost ~]# cat c_kvm_with_qemu-2-7.1_helper_33_fedora.sh #!/bin/bash base_img=/home/fedora25/fedora25-1.img IMAGE=/home/fedora25/test_fedora25-1.img rm -f $IMAGE MEM=8192M qemu-img create -b $base_img -f qcow2 $IMAGE 50G /usr/bin/qemu-system-x86_64 \ -hda $IMAGE \ -net user,hostfwd=tcp::10022-:22 \ -net nic \ -cpu host \ -m ${MEM} \ -pidfile "/tmp/qemu-2-7-1_pid_fedora.txt" \ --enable-kvm \ -chardev socket,id=mon0,host=localhost,port=4444,ipv4,server,nowait \ -mon chardev=mon0,mode=readline Then I ran the modified hotpluig.sh (as mentioned above) and this is what I found. i. The VM oops as it did before in my previous report. ii. In insert_devices(), if i comment out the "ssh_vm scripts/setup.sh" to prevent setup.sh from running, it did not oops, however, inserts of new devices were not found. It appears, the problem may not be the kernel version but running setup.sh more than once is the issue. Daniel, each time setup.sh is ran, it writes 1024 to memory on the proc filesystem (/proc/sys/vm/nr_hugepages) to be used for the allocation of huge pages, could this be the issue since a prior run had already allocated huge pages?

[root@host1 spdk]# /tmp/qemu-2.9.0/x86_64-softmmu/qemu-system-x86_64 -version QEMU emulator version 2.9.0 Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers One observation on (although this is not the problem because I executed the scripts/setup.sh and the hotplug binary from vm console during appropriate breakpoints because local port 10022 was not responsive), the hotplug.h has the flag "-net user,hostfwd=tcp::10022-:22 \" to redirect gust ssh port 22 to host port 10022. However, qemu-system-x86_64 version 2.9 does not have this option but it has -netdev option but is is different. The qemu-system-86_64 man page on -netdev flag is as follows: -netdev user,id=str[,ipv4[=on|off]][,net=addr[/mask]][,host=addr] [,ipv6[=on|off]][,ipv6-net=addr[/int]][,ipv6-host=addr] [,restrict=on|off][,hostname=host][,dhcpstart=addr] [,dns=addr][,ipv6-dns=addr][,dnssearch=domain][,tftp=dir] [,bootfile=f][,hostfwd=rule][,guestfwd=rule][,smb=dir[,smbserver=addr]] configure a user mode network backend with ID 'str', its DHCP server and optional services It says hostfwd=rule and does not give detail of the rule. I used tcp so I specified it as -netdev user,id=hotplug,hostfwd=tcp::10022-:22 \ >From the host "netstat -an |egrep -I listen |less" I see local port 10022 is being listened on. I installed sshpass and tested this -netdev flag redirection with a simple sshpass command to the vm but got no response. Therefore, i bypassed executing scripts/setup.sh and the hotplug binary using sshpass command. So I can test it without executing setup.sh and the hotplug binary through sshpass on port 10022. The main issue is why does it oops after I run it 2 or more times?

An Open, Transparent Patch Submission Process

by Walker, Benjamin

Hi all, We're excited to announce a new patch submission process for SPDK utilizing GerritHub, a hosted code review service integrated with GitHub. All patches, even from SPDK maintainers, will now use the new process, which means all code reviews and discussions are now fully open and transparent to everyone. We encourage everyone, even if you aren't an expert, to review patches and vote with a +1 or -1! A quick query for all open patches is here (better queries and dashboard set up are in the guide at the bottom): https://review.gerrithub.io/#/q/project:spdk/spdk+status:open Further, the SPDK continuous integration tests are hooked up to GerritHub, which means that when you submit a patch a whole battery of tests on a wide range of systems will be run with results reported directly to the code review. You can view the current status of the continuous integration system at: http://ci.spdk.io A comprehensive guide to the new patch submission process can be found here: http://www.spdk.io/development A quick start guide is still in the works. We're thrilled to open this system up to everyone, giving all community members access to the same tools the SPDK maintainers have. Thanks, The SPDK maintainers

VM not booting up with SPDK vhost

by Abhik Sarkar

Hi, This is actually a follow-up email as I was suggested to post the query on the mailing list. So, we are running into an issue while setting up SPDK vhost. Our guest OS does not seem to boot-up after it looks like Qemu has setup communication with the vhost app. We first faced the problem with guest running Scientific Linux 6.1, kernel version 2.6.32-696.1.1.el6. On James Harris’ recommendation, we tried running guest with CentOS 7, kernel version 3.10.0-514.el7.x86_64. But we see the same issue. I have attached 2 different config files. One with the vhost setting and one without. centos7.1.xml : This does not have any vhost related command line arguments while launching the VM Status: The VM launches just fine and we are able to login to the VM vcentos7.1.xml: This one has the vhost setting appended Status: The vhost-target output seems to show that the vhost-client (qemu) has been setup properly (vhost_logs.txt) but we can’t login to the VM. Follwing is the arp output # arp -an centos7.1 -->? (192.168.122.24) at 52:54:00:47:0c:3d [ether] on virbr0 vcentos7.1 -->? (192.168.122.204) at <incomplete> on virbr0 Also the console does not show any boot messages or login prompt. # virsh ttyconsole vcentos7.1 /dev/pts/0 #virsh console vcentos7.1 Connected to domain vcentos7.1 Escape character is ^] The qemu build used is the spdk branch with the latest commit ID being 6eed2b580b6d5bc853b8efc15931eaf0c0de68a2 Thanks/Regards -a

"Open file failed: No such file or directory" error in examples/nvme/nvme_manage/nvme_manage tool

by Isaac Otsiabah

I experimented with examples/nvme/nvme_manage/nvme_manage tool. After the prompt to enter the firmware path name, I entered the firmware full path name and got "Open file failed: No such file or directory" error. After a little debug I found in update_firmware_image(void) function line 775, fgets(..) reads the new line character and puts it at the end of the input buffer. This new line character must be removed from the input buffer before the buffer contents is used. 775 if (fgets(path, 256, stdin) == NULL) { 776 printf("Invalid path setting\n"); 777 while (getchar() != '\n'); 778 return; 779 } The same problem is also in the get_controller() function after fgets is used to read the PCI Address from standard input. 300 while ((ch = getchar()) != '\n' && ch != EOF); 301 p = fgets(address, 64, stdin); 302 if (p == NULL) { 303 return NULL; 304 } Both can be fixed by removing the new line character from the input buffer after fgets return Ie. if (path[strlen(path)-1]=='\n') path[strlen(path)-1]='\0'; Isaac [root@spdk2 spdk]# ./examples/nvme/nvme_manage/nvme_manage Starting DPDK 17.02.0 initialization...

valgrind issues related to spdk

by Rukhsana Ansari

Hi, I tried using valgrind-3.11.0-24.el7.x86_64 for my app based on spdk and found that rte_eal_init->eal_hugepage_info_init->clear_hugedir takes an extremely long time to complete and rte_eal_pci_init() seems to hang. Is valgrind-3.11.0-24.el7.x86_64 supported on spdk? As specified in: https://stackoverflow.com/questions/37386738/error-when-running-dpdk-app-... I built dpdk with set CONFIG_RTE_MACHINE="snb". Based on this other email thread, https://lists.01.org/pipermail/spdk/2017-March/000409.html I tried using *https://github.com/bluca/valgrind-dpdk* <https://github.com/bluca/valgrind-dpdk> valgrind --leak-check=full --show-leak-kinds=all -v -v -v -d -d -d myprog but ran into this error: valgrind: m_deduppoolalloc.c:258 (vgPlain_allocEltDedupPA): Assertion 'eltSzB <= ddpa->poolSzB' failed.

Could not find NVMe controller at PCI address 0000:06:00.0

by Hugh Daschbach

I'm having issues getting app/nvmf_tgt/nvmf_tgt running. I've configured four of five local NVMe devices in nvmf.conf. The devices are discovered during early initialization, but spdk_nvme_probe() fails to find a previously probed device. It looks like nvme_pci_ctrlr_scan() expects a hotplug event that it never sees.
