[libvirt] PATCH: Fix QEMU/UML use of libnuma

by Daniel P. Berrange

The 2.x series of numactl releases changed the ABI/API for certain libnuma.so functions we use. Fortunately it turns out that they provide back-compatability of both ABI and API with a combo of linker script magic, and header file inline compat functions. So, all we need todo is #define NUMA_VERSION1_COMPATIBILITY before include numa.h in our code. This new code did, however, expose a bug in our use of the existing API. We were calculating size in bytes, instead of size in longs, so were passing a buffer that was 8 times to large. Harmless, but the new libnuma validates that the buffer is expected size. So this patch also fixes us to pass & allocate correct buffer size. Finally, also add a missing BuildRequire on numactl-devel, and fixes the libvirtd automake build dependancy Daniel Index: libvirt.spec.in =================================================================== RCS file: /data/cvs/libvirt/libvirt.spec.in,v retrieving revision 1.103 diff -u -p -r1.103 libvirt.spec.in --- libvirt.spec.in 26 Nov 2008 14:46:49 -0000 1.103 +++ libvirt.spec.in 27 Nov 2008 13:20:24 -0000 @@ -124,6 +124,8 @@ BuildRequires: lvm2 BuildRequires: iscsi-initiator-utils # For disk driver BuildRequires: parted-devel +# For QEMU/LXC numa info +BuildRequires: numactl-devel Obsoletes: libvir # Fedora build root suckage Index: qemud/Makefile.am =================================================================== RCS file: /data/cvs/libvirt/qemud/Makefile.am,v retrieving revision 1.61 diff -u -p -r1.61 Makefile.am --- qemud/Makefile.am 21 Nov 2008 12:27:11 -0000 1.61 +++ qemud/Makefile.am 27 Nov 2008 13:20:24 -0000 @@ -87,7 +87,6 @@ libvirtd_LDFLAGS = \ $(COVERAGE_LDFLAGS) \ $(POLKIT_LIBS) -libvirtd_DEPENDENCIES = ../src/libvirt.la libvirtd_LDADD = \ ../gnulib/lib/libgnu.la @@ -129,6 +128,9 @@ libvirtd_CFLAGS += $(AVAHI_CFLAGS) libvirtd_LDADD += $(AVAHI_LIBS) endif +libvirtd_DEPENDENCIES = $(libvirtd_LDADD) + + default_xml_dest = libvirt/qemu/networks/default.xml install-data-local: install-init install-data-sasl install-data-polkit mkdir -p $(DESTDIR)$(sysconfdir)/libvirt/qemu/networks/autostart Index: src/qemu_conf.c =================================================================== RCS file: /data/cvs/libvirt/src/qemu_conf.c,v retrieving revision 1.108 diff -u -p -r1.108 qemu_conf.c --- src/qemu_conf.c 19 Nov 2008 16:58:23 -0000 1.108 +++ src/qemu_conf.c 27 Nov 2008 13:20:24 -0000 @@ -37,6 +37,7 @@ #include <sys/utsname.h> #if HAVE_NUMACTL +#define NUMA_VERSION1_COMPATIBILITY 1 #include <numa.h> #endif @@ -300,11 +301,11 @@ qemudCapsInitGuest(virCapsPtr caps, #if HAVE_NUMACTL #define MAX_CPUS 4096 #define MAX_CPUS_MASK_SIZE (sizeof(unsigned long)) -#define MAX_CPUS_MASK_LEN (MAX_CPUS / MAX_CPUS_MASK_SIZE) -#define MAX_CPUS_MASK_BYTES (MAX_CPUS / 8) +#define MAX_CPUS_MASK_BITS (MAX_CPUS_MASK_SIZE * 8) +#define MAX_CPUS_MASK_LEN (MAX_CPUS / (MAX_CPUS_MASK_BITS)) #define MASK_CPU_ISSET(mask, cpu) \ - (((mask)[((cpu) / MAX_CPUS_MASK_SIZE)] >> ((cpu) % MAX_CPUS_MASK_SIZE)) & 1) + (((mask)[((cpu) / MAX_CPUS_MASK_BITS)] >> ((cpu) % MAX_CPUS_MASK_BITS)) & 1) static int qemudCapsInitNUMA(virCapsPtr caps) @@ -322,7 +323,8 @@ qemudCapsInitNUMA(virCapsPtr caps) goto cleanup;

[libvirt] Hide fully-virtualized network devices to domU with PV drivers

by Iain Watson

Hello, I have a problem with libvirt which I hope someone on this list might be able to help with. I have many DomU images which all have PV drivers loaded for network. I want to start these DomU guests with only the PV network device being visible from within the DomU. In testing I have been able to create the required system with the 'xm' command. The important part of the network line is "type=none". The complete line looks like: vif = [ "mac=00:16:3e:00:a5:57,bridge=eth0,script=vif-bridge,type=none" ] With libvirt I have tried adding "<model type='none'/>" into the interface section but this errors with "qemu: Unsupported NIC: none" so I'm obviously missing something obvious. The complete interface section looks like: <interface type='bridge'> <mac address='00:16:3e:00:a5:57'/> <source bridge='eth0'/> <target dev='vif9.0'/> <model type='none'/> </interface> I have been able to achieve the required configuration if I completely omit an 'interface' section and once the DomU has booted I use virsh to add an interface to the domain. Unfortunately if I then reboot the DomU the guest comes back up with two network interfaces visible to it and the qemu-dm line has added a "-net ...,model=rtl8139" option. Having hunted around I am yet to find a way to configure a domU in libvirt so the networking available to the guest is the way I require. As I can do this with xm, I'm hoping someone on this list can point me in the right direction to also do this with libvirt. Thanks in advance, Iain Watson

[libvirt] [PATCH 1/2]: Give /dev/disk/by-{id, path} a chance to exist

by Chris Lalancette

This patch is the same idea as my previous patch for giving /dev/disk/by-{id,path} a chance to exist. Currently libvirt can race with udev creation of /dev/disk/by-{id,path}, so if we fail to open the directory, retry up to 5 seconds. This is only likely to happen on hosts that are: 1) diskless (so /dev/disk/by-{id,path} doesn't exist already), and 2) slow, and/or heavily loaded (meaning that udev can take some time to create the /dev nodes). Based on the feedback from Dan and Jim, I updated the patch to look more like what is elsewhere in libvirt.

[libvirt] PATCH: Allow automatic driver probe for remote TCP connections

by Daniel P. Berrange

When connecting to a local libvirt you can let it automatically probe the hypervisor URI if you don't know it ahead of time. This doesn't work with remote URIs because you need to have something to put in the URI scheme before the hostname qemu+ssh://somehost/system xen+tcp://somehost/system This is then translated into the URI qemu:///system xen:/// It occurred to me that we can trivially enable probing with all existing libvirtd daemon releases, simply by fixing the client side. All we need todo is invent a new generic URI scheme, and convert that to empty string This patch adds a 'remote' URI scheme, usable like this remote+ssh://somehost/ remote+tcp://somehost/ remote://somehost/ remote+tls://somehost/ remote+ext://somehost/ In all these styles, the URI passed to the remote daemon is "", causing it to probe. As a demonstration, here's an example using virsh and two hosts I have, one running Xen, the other QEMU See it automatically choosing QEMU.... $ virsh --connect remote+ssh://root@lettuce/ version Compiled against library: libvir 0.5.0 Using library: libvir 0.5.0 Running hypervisor: QEMU 0.9.1 And choosing Xen.... $ virsh --connect remote+ssh://root@pumpkin/ version Compiled against library: libvir 0.5.0 Using library: libvir 0.5.0 Running hypervisor: Xen 3.1.0 This finally makes the Avahi broadcasts useful - they only include info on the hostname + data transport (SSH, TCP, TLS), not the HV type. So letting us use auto-probing remotely is the missing link. NB. we've got a small problem with the virGetVersion() API - it does not take a connection URI - just a hypervisor type. It then directly checks the statically declared 'version' field in the virDriverPtr struct. This no longer works now that some drivers are linked directly into the libvirt daemon. I'm thinking that perhaps we can just change the virGetVersion() apis so that instead of looking in virDriverPtr struct, we just include the version numbers directly in virGetVersion as a static const lookup table. Meanwhile, this patch also includes a change to virsh to stop it calling virGetVersion(), though this hunk instead intended to apply to CVS.

All, This is a 2 part patch series to make libvirt backend device scanning more reliable. In particular, this is important for things that can create/destroy udev /dev nodes, since at present we can race with the udev creation. Note that this takes over the previous patch that I posted to retry /dev/disk/by-{id,path} scanning. Signed-off-by: Chris Lalancette <clalance(a)redhat.com>

[libvirt] make not invoking rpcgen remote_protocol.x

by Kenneth Nagin

I am attempting to add some new libvirt functions that I intend to submit for your approval. I have made changes to remote_protocol.x. Initially it generated the expected files. However, after making a few changes the make no causes it to generate files. Manually invoke rpcgen -c remote_protocol.x > remote_protocol.c seems to get around the compile problem. But now I'm getting a "Remote error : marshaling args" I 'm think there is a problem in the make. Kenneth Nagin

[libvirt] serial console runs out of buffer and console messages soft lock the CPU

by Bryan McLellan

I recently started configuring guests to use both a serial console and a graphics element. One of the nodes with this configuration kept locking up after running for some time. Trying to access the guest through virt-manager would leave virt-viewer hung at the connecting to screen. The guest would not respond to any network traffic including icmp. The user would destroy the domain and restart it to recover. Eventually the problem came to me and I found that immediately upon running 'virsh console domain' the guest would recover. The console contained: BUG: soft lockup - CPU#0 stuck for 94393s! [postgresql-8.3:4975] I discovered a bug in a puppet recipe caused postgres to reload regularly, printing a message to the console each time. Running puppet in a loop to continue producing these messages to the console caused another lockup that was recoverable by accessing the serial console in the same manner. I have since fixed that recipe, but I'm uncomfortable about the possibility of this happening again. Is there a way to configure libvirt to cache the serial console on the host so the buffer on the guest does not fill up when you aren't connected to the console, or should I disable the serial console?

If you have python 2.6, then just add the '-3' flag to the command line in order to warn about features which are deprecated and will be removed in Python 3. ** For the OCaml based tools (virt-df, virt-top): mingw32-ocaml mingw32-ocaml-calendar mingw32-ocaml-csv mingw32-ocaml-curses mingw32-ocaml-extlib mingw32-ocaml-findlib mingw32-ocaml-lablgl mingw32-ocaml-lablgtk mingw32-ocaml-libvirt mingw32-ocaml-xml-light (None of these are in Bugzilla yet, and for good reason because I may just do them as subpackages of the OCaml packages already in Fedora). ** I haven't had any particular requests for Ruby tools yet. OVirt itself is a standalone appliance and it doesn't need porting to Windows. ovirt-viewer is a C application and is being written concurrently on Linux and Windows anyway. I'm not sure if there are other standalone bits of ovirt which would make sense being ported to Windows.
