[libvirt] [PATCH] Revert "admin: Rename virAdmConnect to virAdmDaemon"
by Erik Skultety
Commmit df8192aa introduced admin related rename and some minor
(caused by automated approach, aka sed) and some more severe isues along with
it. First reason to revert is the inconsistency with libvirt library.
Although we deal with the daemon directly rather than with a specific
hypervisor, we still do have a connection. That being said, contributors might
get under the impression that AdmDaemonNew would spawn/start a new daemon
(since it's admin API, why not...), or AdmDaemonClose would do the exact
opposite or they might expect DaemonIsAlive report overall status of the daemon
which definitely isn't the case.
The second reason to revert this patch is renaming virt-admin client. The
client tool does not necessarily have to reflect the names of the API's it's
using in his internals. An example would be 's/vshAdmConnect/vshAdmDaemon'
where noone can be certain of what the latter function really does. The former
is quite expressive about some connection magic it performs, but the latter does
not say anything, especially when vshAdmReconnect and vshAdmDisconnect were
left untouched.
---
The admin API rename is not entirely bad idea (e.g. virAdmDaemonGetURI sounds
a little better than virAdmConnectGetURI), so by introducing this patch
I'd like to reopen the discussion about what we could/should rename
(if anything) and which parts should definitely be left untouched, because
there is still time to do somthing with it since admin is disabled and not
distributed in the package.

[libvirt] [PATCH V2] Xen: support maxvcpus in xm and xl config
by Jim Fehlig
From: Ian Campbell <ian.campbell(a)citrix.com>
xend prior to 4.0 understands vcpus as maxvcpus and vcpu_avail
as a bit map of which cpus are online (default is all).
xend from 4.0 onwards understands maxvcpus as maxvcpus and
vcpus as the number which are online (from 0..N-1). The
upstream commit (68a94cf528e6 "xm: Add maxvcpus support")
claims that if maxvcpus is omitted then the old behaviour
(i.e. obeying vcpu_avail) is retained, but AFAICT it was not,
in this case vcpu==maxcpus==online cpus. This is good for us
because handling anything else would be fiddly.
This patch changes parsing of the virDomainDef maxvcpus and vcpus
entries to use the corresponding 'maxvcpus' and 'vcpus' settings
from xm and xl config. It also drops use of the old Xen 3.x
'vcpu_avail' setting.
The change also removes the maxvcpus limit of MAX_VIRT_VCPUS (since
maxvcpus is simply a count, not a bit mask), which is particularly
crucial on ARM where MAX_VIRT_CPUS == 1 (since all guests are
expected to support vcpu placement, and therefore only the boot
vcpu's info lives in the shared info page).
Existing tests adjusted accordingly, and new tests added for the
'maxvcpus' setting.
Signed-off-by: Jim Fehlig <jfehlig(a)suse.com>
---
This is a respin of Ian's patch [1] to support parsing/formatting of the
'maxvcpus' xm and xl config setting. It goes a bit further and removes
the old Xen 3.x 'vcpu_avail' setting and lifts the maxvcpus limit of
MAX_VIRT_CPUS entirely.
The patch is based on my recent series [2] removing xend config version from
the codebase.

[libvirt] TSO of VM packets degardes significantly on increasing VM's on a Host
by Piyush R Srivastava1
Hi,
Problem-
Offloading for VM packets (TSO enabled in VM's ) degrades severely with
increase in VM's on a host
What is controlling the offloading of VM packets and how can we improve
it ?
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Description-
We have a testbed OpenStack deployment. We boot 1, 10 and 25 VM's on a
single compute node and start iperf traffic. ( VM's are iperf client ).
We then simultaneously do tcpdump at the veth-pair connecting the VM to the
OVS Bridges.
Tcpdump data shows that on increasing the VM's on a host, the % of
offloaded packets degrades severely
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Host configuration- 12 cores ( 24 vCPU ), 40 GB RAM
[root@rhel7-25 ~]# uname -a
Linux rhel7-25.in.ibm.com 3.10.0-229.el7.x86_64 #1 SMP Thu Jan 29 18:37:38
EST 2015 x86_64 x86_64 x86_64 GNU/Linux
VM MTU is set to 1450
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Analysis-
------------------------------------------------------------------------------------
| VMs | % Non-Offloaded packets |
|-----------------------------------------------------------------------------------|
| 1 | 11.11% |
| 10 | 71.78% |
| 25 | 80.44% |
|-----------------------|-----------------------------------------------------------|
Thus we see significant degradation in offloaded packets when 10 and 25
VM's are sending iperf data simultaneously. ( TSO enabled VM's )
Non-Offloaded packets means Ethernet Frame of size 1464 ( VM MTU is 1450 )
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Tcpdump details-
Iperf Server IP- 1.1.1.34
For 1 VM, we see majority offloaded packets-

[libvirt] TSO of VM packets degardes significantly on increasing VM's on a Host
by Piyush R Srivastava1
Hi,
Problem-
Offloading for VM packets (TSO enabled in VM's ) degrades severely with
increase in VM's on a host
What is controlling the offloading of VM packets and how can we improve
it ?
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Description-
We have a testbed OpenStack deployment. We boot 1, 10 and 25 VM's on a
single compute node and start iperf traffic. ( VM's are iperf client ).
We then simultaneously do tcpdump at the veth-pair connecting the VM to the
OVS Bridges.
Tcpdump data shows that on increasing the VM's on a host, the % of
offloaded packets degrades severely
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Host configuration- 12 cores ( 24 vCPU ), 40 GB RAM
[root@rhel7-25 ~]# uname -a
Linux rhel7-25.in.ibm.com 3.10.0-229.el7.x86_64 #1 SMP Thu Jan 29 18:37:38
EST 2015 x86_64 x86_64 x86_64 GNU/Linux
VM MTU is set to 1450
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Analysis-
------------------------------------------------------------------------------------
| VMs | % Non-Offloaded packets |
|-----------------------------------------------------------------------------------|
| 1 | 11.11% |
| 10 | 71.78% |
| 25 | 80.44% |
|-----------------------|-----------------------------------------------------------|
Thus we see significant degradation in offloaded packets when 10 and 25
VM's are sending iperf data simultaneously. ( TSO enabled VM's )
Non-Offloaded packets means Ethernet Frame of size 1464 ( VM MTU is 1450 )
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Tcpdump details-
Iperf Server IP- 1.1.1.34
For 1 VM, we see majority offloaded packets-

[libvirt] [PATCH 0/2] 'deflate-on-oom' attribute for mememory balloon
by Dmitry Andreev
This patch-set adds support for the new feature that has
been added to the QEMU virtio memory balloon a month ago.
This feature lets a guest OS deflate balloon on OOM.
With 'deflate-on-oom' enabled virtio balloon will release
it's memory if possible right before an OOM termination of
processes.
QEMU commit with the complete feature description:
http://git.qemu.org/?p=qemu.git;a=commit;h=e3816255bf4b6377bb405331e2ee0d...

[libvirt] [PATCH] lxc_cgroup: Add check for NULL cgroup before AddTask call
by John Ferlan
Commit id '71ce4759' altered the cgroup processing with respect to the
call to virCgroupAddTask being moved out from lower layers into the calling
layers especially for qemu processing of emulator and vcpu threads. The
movement affected lxc insomuch as it is possible for a code path to
return a NULL cgroup *and* a 0 return status via virCgroupNewPartition
failure when virCgroupNewIgnoreError succeeded when virCgroupNewMachineManual
returns. Coverity pointed out that would cause virCgroupAddTask to core.
This patch will check for a NULL cgroup as well as the negative return
and just return the NULL cgroup to the caller (as it would have previously)

[libvirt] [PATCH 0/8] Use macros for more common virsh command options
by John Ferlan
As a follow on to a recent series which created macros for various
virsh-*.c command options, see:
http://www.redhat.com/archives/libvir-list/2015-December/msg00672.html
(although best to view by index since there are varying opinions on
the matter)...
Modify virsh-domain.c and virsh-volume.c to "follow" the concept of
macro-ifying some commonly used options. In order to choose, I used:
$ grep "{.name =" tools/virsh-*.c | \
grep -v "help" | grep -v "desc" | grep -v NULL | \
sort -i | uniq -c | sort -n
To generate a list by module. That generated a list where I randomly
picked 9 as the nexus, leaving the following:
9 tools/virsh-domain.c: {.name = "persistent",
10 tools/virsh-snapshot.c: {.name = "domain",
12 tools/virsh-network.c: {.name = "network",
12 tools/virsh-pool.c: {.name = "pool",
13 tools/virsh-volume.c: {.name = "vol",
14 tools/virsh-domain.c: {.name = "file",
14 tools/virsh-domain-monitor.c: {.name = "domain",
14 tools/virsh-volume.c: {.name = "pool",
26 tools/virsh-domain.c: {.name = "current",
28 tools/virsh-domain.c: {.name = "config",
28 tools/virsh-domain.c: {.name = "live",
81 tools/virsh-domain.c: {.name = "domain",
Because virsh-domain-monitor.c, virsh-network.c, and virsh-snapshot.c
only had one element with larger counts - I just left them as is and
focused on the virsh-domain.c and virsh-volume.c.
The perhaps more controversial choice will be the "file" option in
virsh-domain.c which had numerous different helpstr values. I chose
to macro-ify them using the entire helpstr including the N_("xxx")
rather than just "xxx" since the N_ is the I18N marker.
John Ferlan (8):
virsh: Create macro for common "domain" option
virsh: Create macro for common "persistent" option
virsh: Create macro for common "config" option
virsh: Create macro for common "live" option
virsh: Create macro for common "current" option
virsh: Create macro for common "file" option
virsh: Create macros for common "pool" options
virsh: Create macros for common "vol" options
