So it's possible to have exactly the same QEMU command-line on source and destination (with an explicit versioned machine-type), and get a VM that can't be migrated? That means we are breaking our guarantees about migration and guest ABI. > We could change this for the next machine type to always force > max alignment (1Gb), then it would be possible to change > between backends with different alignments. I'm not sure what's the best solution here. If always using 1GB is too aggressive, we could require management to ask for an explicit alignment as a -machine option if they know they will need a specific backend page size. BTW, are you talking about the behavior introduced by aa8580cddf011e8cedcf87f7a0fdea7549fc4704 ("pc: memhp: force gaps between DIMM's GPA") only, or the backend page size was already affecting GPA allocation before that commit? -- Eduardo

[libvirt] Again cgroups and isolcpus
by Henning Schild 29 Oct '15

29 Oct '15

Hi folks, i already started a discussion on the interaction of cgroups and isolcpus a while ago. But now i believe i have got a better understanding of how the two interact and i can describe problems that arise from that. The scenario: A machine that runs realtime tasks on pcpus reserved with isolcpus. It also runs VMs with the help of libvirt. It might also run realtime VMs with the help of libvirt. Moving a task into a new cgroup/cpuset and some modifications of the cpus in that set imply a setaffinity by the kernel. That affinity setting will ignore isolcpus. The result is possible "interference by" or "starvation of" these tasks. Now let me describe one scenario where that implicit setaffinity becomes a problem for our realtime system. libvirt creates a superset called the machine.slice and subsets called emulator and vpuX. By default the machine.slice inherits from the root which contains all pcpus, also the isolated ones. Now moving a task into that superset will place that task on isolcpus where it might interfere or simply starve. Turns out that a fresh qemu actually is put into that superset. That is a bug that should be fixed but let me address that one in another mail. My current point of view is that we need a strong mechanism to isolate cpus. isolcpus just is not good enough. The measure of choice probably is cpusets as well, and this time with the exclusive flag turned on. That will stop every other cpuset user from messing around with those cpus by accident. I am thinking of one or more cpusets where isolated cpus are parked and not used within this cgroup. Anyone wanting to use one of them will have to take it out there and explictily put it into their a new set. Now if libvirt makes the mistake to have tasks running in supersets these tasks will spread to the newly added rt-cpu. Or new tasks that run in supersets will end up on rt-cpus already in use. But at least we have containment in libvirt and the VMs it spawned. For alloc and free of rt-cpus i am planning to use libvirt hooks to begin with, from what i read they should enable me to do what i need. What do you guys think about the general idea to address the described problem? I will implement a prototype of the alloc-free of rt-cpus. My current hope is that libvirt hooks can be abused for that. I am thinking that at some point libvirt should be able to do that without hooks. It should get a notion of reserved ressources that are currently parked in other cgroups. My current suspicion is that the cpusets might just be the tip of the iceberg. -- for now i am running libvirt without cgroups to keep my isolcpus free cgroups/cpusets offer a switch to make a cpu exclusive to a set. That switch is great because it will act as an assert, a second line of defense. Having seen how cpusets and migration mess around with affinities i guess for realtime people have to insist on that second line of defense. Especially in times where cgroups are all over the place. In openstack one would actually say that a pcpu should be "dedicated". That will result in a vcpupin on exactly one pcpu. Unfortunately one meaning of "dedicated" gets lost in translation. It could otherwise be used by libvirtd to set cpuset.cpu_exclusive in the vcpu-cgroup. And i am bringing that up here because i do not think libvirt allows me to influence the cpu_exclusive flag for my vcpu cgroups. Henning

[libvirt] [PATCH] wireshark: Install to generic plugin directory
by Michal Privoznik 29 Oct '15

29 Oct '15

There has been a report on the list [1] that we are not installing the wireshark dissector into the correct plugin directory. And in fact we are not. The problem is, the plugin directory path is constructed at compile time. However, it's dependent on the wireshark version, e.g. /usr/lib/wireshark/1.12.6/plugins/ This is rather unfortunate, because if libvirt RPMs were built with one version, but installed on a system with newer one, the plugins are not really loaded. This problem lead fedora packagers to unify plugin path to: /usr/lib/wireshark/plugins/ Cool! But this was enabled just in wireshark-1.12.6-4. Therefore, we must require at least that version. And while at it, on some distributions, the wireshark.pc file already has a variable that defines where plugin dir is. Use that if possible. 1: https://www.redhat.com/archives/libvirt-users/2015-October/msg00063.html Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- libvirt.spec.in | 6 ++++-- m4/virt-wireshark.m4 | 7 ++++++- 2 files changed, 10 insertions(+), 3 deletions(-) diff --git a/libvirt.spec.in b/libvirt.spec.in index 9dff994..469bfca 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -1170,7 +1170,7 @@ virtualization capabilities of recent versions of Linux (and other OSes). %package wireshark Summary: Wireshark dissector plugin for libvirt RPC transactions Group: Development/Libraries -Requires: wireshark +Requires: wireshark >= 1.12.6-4 Requires: %{name}-client = %{version}-%{release} %description wireshark @@ -1561,6 +1561,8 @@ rm -f $RPM_BUILD_ROOT%{_libdir}/libvirt/connection-driver/*.a %endif %if %{with_wireshark} rm -f $RPM_BUILD_ROOT%{_libdir}/wireshark/plugins/*/libvirt.la +mv $RPM_BUILD_ROOT%{_libdir}/wireshark/plugins/*/libvirt.so \ + $RPM_BUILD_ROOT%{_libdir}/wireshark/plugins/libvirt.so %endif # Temporarily get rid of not-installed libvirt-admin.so @@ -2279,7 +2281,7 @@ exit 0 %if %{with_wireshark} %files wireshark -%{_libdir}/wireshark/plugins/*/libvirt.so +%{_libdir}/wireshark/plugins/libvirt.so %endif %if %{with_lxc} diff --git a/m4/virt-wireshark.m4 b/m4/virt-wireshark.m4 index 47204ed..199317e 100644 --- a/m4/virt-wireshark.m4 +++ b/m4/virt-wireshark.m4 @@ -28,7 +28,12 @@ AC_DEFUN([LIBVIRT_CHECK_WIRESHARK],[ dnl Check for system location of wireshark plugins if test "x$with_wireshark_dissector" != "xno" ; then if test "x$with_ws_plugindir" = "xcheck" ; then - ws_plugindir="$libdir/wireshark/plugins/$($PKG_CONFIG --modversion wireshark)" + ws_plugindir="$($PKG_CONFIG --variable plugindir wireshark)" + if test "x$ws_plugindir" = "x" ; then + dnl On some systems the plugindir variable may not be stored within pkg config. + dnl Fall back to older style of constructing the plugin dir path. + ws_plugindir="$libdir/wireshark/plugins/$($PKG_CONFIG --modversion wireshark)" + fi elif test "x$with_ws_plugindir" = "xno" || test "x$with_ws_plugindir" = "xyes"; then AC_MSG_ERROR([ws-plugindir must be used only with valid path]) else -- 2.4.10

[libvirt] virsh can't support VM offline blockcommit
by justlibvirt＠gmail.com 29 Oct '15

29 Oct '15

Hi everyone! I use the libvirt(version: 1.2.2) and QEMU(version: 2.2.1) to test qemu snapshot features: I tried virsh blockcommit when VM offline, the virsh blockcommit failed: the error messase as below: error: Requested operation is not valid: domain is not running when I start the VM, the virsh blockcommit work fine! my question is：we need virsh support blockcommit when VM offline。how do？ we test qemu snapshot as follows： we need create snapshot of the cycle，and by virsh blockcommit merge snapshot chain，but when VM offline， the virsh blockcommit will fail， someone suggest me：when VM offline，may use qemu-img commit to submit snapshot turn，but qemu-img can't modify snapshot chain backing relation，it need we use qemu-img rebase amend snapshot‘s backingfile， the main question is when we use qemu-img rebase modify snapshot's backingfile, if someone start the VM, it will may lead to VM filesystem readonly。 we should how to solve the question? thanks! justlibvirt(a)gmail.com
