[libvirt] [libivrt] storage: Two iSCSI node records may cause refreshing iscsi pool failed
by Shichangkuo 06 Jan '17

06 Jan '17

Hi, John When starting an iscsi storage pool, libvirt will execute “iscsiadm --mode node --portal 192.168.0.42 --targetname iqn.2003-10.com.xxxx --op new”, which is called by virISCSINodeNew. This will add an iSCSI node record. The record file is /etc/iscsi/nodes/iqn.2003-10.com.xxxx/192.168.0.42,3260. When we already executed "iscsiadm --mode discovery --type sendtargets --portal 192.168.0.42 --op new", another iSCSI node record will be produced in /etc/iscsi/nodes/iqn.2003-10.com.xxxx/192.168.0.42,3260,1/default. Then two iscsi sessions, as [2] and [3], will be logged in when we start the pool. Device of session [2] is /dev/sde, and device of session [3] is /dev/sdf. But there is only one path in /dev/disk/by-path, let's assume it is /dev/sdf. Refreshing storage pool will choose first session, like [2], and libvirt will find sde NOT sdf in /dev/disk/by-path. We will not find sde, then no volumes is found in the pool. I think the root reason is we have two iSCSI node records. Can we use "iscsiadm --mode discovery --type sendtargets --portal 192.168.0.42 --op new" in virISCSINodeNew? diff --git a/src/util/viriscsi.c b/src/util/viriscsi.c index 504ffbd..a8a8644 100644 --- a/src/util/viriscsi.c +++ b/src/util/viriscsi.c @@ -469,9 +469,9 @@ virISCSINodeNew(const char *portal, int ret = -1; cmd = virCommandNewArgList(ISCSIADM, - "--mode", "node", + "--mode", "discovery", + "--type", "sendtargets", "--portal", portal, - "--targetname", target, "--op", "new", NULL); Thanks, Changkuo. ------------------------------------------------------------------------------------------------------------------------------------- 本邮件及其附件含有杭州华三通信技术有限公司的保密信息，仅限于发送给上面地址中列出的个人或群组。禁止任何其他人以任何形式使用（包括但不限于全部或部分地泄露、复制、或散发）本邮件中的信息。如果您错收了本邮件，请您立即电话或邮件通知发件人并删除本邮件！ This e-mail and its attachments contain confidential information from H3C, which is intended only for the person or entity whose address is listed above.

[libvirt] [PATCH] internal: Simplify STREQ_NULLABLE
by Michal Privoznik 05 Jan '17

05 Jan '17

Our STREQ_NULLABLE and STRNEQ_NULLABLE macros are too complicated. This was a result of some broken version of gcc. However, that is long gone and therefore we can simplify the macros.

The release note process we have had in place since v2.5.0 was never meant to be anything more than a stop-gap measure until a better solution was devised.

[libvirt] Loosing lxc guests when restarting libvirt
by Christian Ehrhardt 05 Jan '17

05 Jan '17

Hi, I found an issue in libvirt related to libvirt-lxc, but fail to find the root cause. The TL;DR is: libvirt-lxc guests get killed on libvirt restart due to "internal error: No valid cgroup for machine" It was able to reproduce libvirt 1.3.1, 2.4 and 2.5 as packages in Ubuntu and Debian. I wanted to ask for two things: - wider coverage where this does reproduce - your expertise on the case itself. Steps to reproduce: 1. Spawn new KVM Guest of your choice 2. install test dependencies $ apt-get install libvirt-daemon-system libvirt-clients libxml2-utils # or package managers / package names of your chosen os 3. run the following sequence as root export LIBVIRT_DEFAULT_URI=lxc:/// cat << EOF > /tmp/smoke-lxc.xml <domain type='lxc'> <name>sl</name> <memory unit='KiB'>256000</memory> <currentMemory unit='KiB'>256000</currentMemory> <vcpu placement='static'>1</vcpu> <os> <type>exe</type> <init>/bin/bash</init> </os> <features> <privnet/> </features> <clock offset='utc'/> <devices> <emulator>/usr/lib/libvirt/libvirt_lxc</emulator> <filesystem type='mount' accessmode='passthrough'> <source dir='/'/> <target dir='/'/> </filesystem> <console type='pty'> <target type='lxc' port='0'/> </console> </devices> </domain> EOF virsh define /tmp/smoke-lxc.xml virsh start sl virsh list --all # is running now /etc/init.d/libvirtd restart virsh list --all # is no more running, but it should Way more background and detail can be found at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=848317 -- Christian Ehrhardt Software Engineer, Ubuntu Server Canonical Ltd
