[libvirt] [PATCH] trying to close some potential FILE * leaks
by Daniel Veillard 16 Mar '09

[libvirt] qemu-kvm networking speed
by Bryan_Coleman＠dart.biz 13 Mar '09

13 Mar '09

How do I change the networking speed provided to my qemu-kvm guest? I have four gigabit ports bonded; however, my guest is showing just 100Mb/s. I have used iperf to confirm. I am not sure if the settings would be on the guest or server side. Any help would be greatly appreciated! Thank you, Bryan

[libvirt] PATCH: Don't try to close unopened connections
by Daniel P. Berrange 13 Mar '09

13 Mar '09

The autostart code for UML and QEMU drivers had a place where it might try to close a connection that is not open. This is harmless because virConnectClose() checks for NULL, but it still causes an annoying diagnosistic to be printed.

[libvirt] libvirt usage
by Zvi Dubitzky 13 Mar '09

13 Mar '09

Hi I have a Ubutnu system . I installed libxml2 and libvirt packages by : apt-get install ibvirt-bin and .. libxml2 . They were installed ok . The libraries are located under /user/lib e.g : /usr/lib/libvirt.so.0 I am trying to link as follows: CFLAGS=`pkg-config --cflags libvirt` LDFLAGS=`pkg-config --libs libvirt` gcc -o test_cpu $CFLAGS $LDFLAGS test_cpu.c But get the message : Package libvirt was not found in the pkg-config search path. Perhaps you should add the directory containing `libvirt.pc' to the PKG_CONFIG_PATH environment variable No package 'libvirt' found It turns out that doing : pkg-config --list-all | grep libvirt return no libvirt traces . just as in the file below . On another older machine that links fine - libvirt is found with the above pkg-config but there is no PKG_CONFIG_PATH env variable as well . Both machines PATH is the same . Did I miss something during the install of the first machine. Any remedy ?

[libvirt] PATCH: Fix node device APIs for RHEL-5 vintage HAL
by Daniel P. Berrange 12 Mar '09

12 Mar '09

In the node device APIs we look for a property in HAL call info.subsystem. Turns out this is a fairly recent addition to HAL, and it used to be called 'linux.subsystem' in RHEL-5 vintage & earlier. This means we never see any PCI / USB devices in libvirt when on RHEL-5. This patch makes us check for both those properties, since the values are the same for each - just the property name changed Daniel Index: src/node_device_hal.c =================================================================== RCS file: /data/cvs/libvirt/src/node_device_hal.c,v retrieving revision 1.9 diff -u -p -r1.9 node_device_hal.c --- src/node_device_hal.c 2 Mar 2009 17:41:13 -0000 1.9 +++ src/node_device_hal.c 12 Mar 2009 14:07:12 -0000 @@ -357,7 +357,8 @@ static int gather_capabilities(LibHalCon goto failure; } - if (get_str_prop(ctx, udi, "info.subsystem", &bus_name) == 0) { + if (get_str_prop(ctx, udi, "info.subsystem", &bus_name) == 0 || + get_str_prop(ctx, udi, "linux.subsystem", &bus_name) == 0) { rv = gather_capability(ctx, udi, bus_name, &caps); if (rv != 0) goto failure; -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|

[libvirt] xen+ssh:// "ghost" connections
by Nick Moffitt 12 Mar '09

12 Mar '09

Many thanks to Daniel Veillard for the Xen storage patch that was ACKed here yesterday! It does indeed seem to fix the crashing and lockup problems I was seeingw hen performing many simultaneous operations. At the moment, it may have exposed something else I find curious. I have a set of twelve VMs across two hosts (seven on one, five on the other). At night they're all paused, and in the morning they're all resumed at once. For the past two evenings, the pause operation has stalled for two of the VMs. The first time it was one per host, and just yesterday it was both on the 7-domain host. These connections are mostly harmless. The libvirtd still accepts new connections, but I can see the stalled ssh/netcat processes still running to forward the local socket. I've attached (okay, pasted inline) a traceback of the daemon that had two ghost connections, and from my inexperienced read-through it looks as though libvirtd doesn't even know that anyone's trying to talk to it. This isn't much to go on, but I felt it was better to post this than to let it drop on the floor, since there does seem to be a pattern so far (we'll see how things go tonight, and I'll be able to do more destructive testing next week).

[libvirt] Looking for good example API function(s)
by Laine Stump 11 Mar '09

11 Mar '09

To help with lutter's network configuration project, I'm looking at adding API functions to libvirt which are essentially pass-throughs to netcf library APIs called by libvirtd. Can someone point me to good examples of APIs that are not hypervisor driver-dependent (and possibly not host OS-dependent either - I believe the final intent is for netcf to handle all host OS dependencies itself) to use as a basis for writing these new APIs? At a more detailed level, a quick trace through the code of some other APIs got me as far as the call to the "call" function, with an RPC code, but I didn't find where that call was caught (and the RPC code interpreted, eg REMOTE_PROC_NETWORK_CREATE_XML - cscope couldn't find any other reference to this value) on the libvirtd side. I'm about run virsh and libvirtd under gdb to learn this by experimentation, but if someone wants to take the fun out of it for me, hints would be gladly accepted! ;-)

[libvirt] PATCH: Support SASL auth for QEMU VNC servers
by Daniel P. Berrange 11 Mar '09

11 Mar '09

This patch adds a config option to /etc/libvirt/qemu.conf to allow the enablement of SASL authentication of the QEMU VNC servers. The patches to QEMU are posted upstream, and though their merge is delayed while the QEMU release is sorted out, I expect them to be merged in a week or so. I'm posting this patch for review now, though best not to commit it to CVS until the QEMU stuff is finally merged.

[libvirt] [patch 0/4] checkpoint functionality
by Matt McCowan 11 Mar '09

11 Mar '09

OK. Another run at producing a function that helps the likes of me backup my kvm Windows servers. 'virsh checkpoint domain file [script]' is what the following patch set (against cvs) enables. Modelled on the virDomainSave function it takes an optional script which it will execute (and pass the name of the domain as an argument) while the domain is paused, then resume the domain. By the by stability is coming along nicely since 0.6.0. Thanks! Matt McCowan
