[libvirt] [libivrt] storage: Two iSCSI node records may cause refreshing iscsi pool failed
by Shichangkuo
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?

[libvirt] [PATCH] internal: Simplify STREQ_NULLABLE
by Michal Privoznik
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.

[libvirt] [PATCH 0/3] Improve release notes process
by Andrea Bolognani
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. I believe this series
implements exactly that better solution :)

NEWS: Reformat at generation time

Hi Michal

then I found you had some code get merged, and required to use /dev/mqueue

[libvirt] Loosing lxc guests when restarting libvirt
by Christian Ehrhardt
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>

[libvirt] [PATCH] qemu: snapshot: restart CPUs when recover from interrupted snapshot job
by Wangjing (King, Euler)
If we restart libvirtd while VM was doing external memory snapshot, VM's
state be updated to paused as a result of running a migration-to-file
operation, and then VM will be left as paused state. In this case we must
restart the VM's CPUs to resume it.
