[libvirt] [PATCH] Automatically pause QEMU guests when an error occurs
by Daniel P. Berrange 18 Feb '10

18 Feb '10

With the QMP mode monitor, it is possible to get a notification that a disk I/O error occurs ina guest. This patch enables such reporting and when receiving an error updates libvirt's view of the guest to indicate that it is now paused. It also emits an event VIR_DOMAIN_EVENT_SUSPENDED with a detail of: VIR_DOMAIN_EVENT_SUSPENDED_IOERROR * include/libvirt/libvirt.h.in: Add VIR_DOMAIN_EVENT_SUSPENDED_IOERROR * src/qemu/qemu_driver.c: Update VM state to paused when IO error occurrs * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h, src/qemu/qemu_monitor_json.c: Wire up handlers for disk IO errors --- include/libvirt/libvirt.h.in | 1 + src/qemu/qemu_conf.c | 7 +++++-- src/qemu/qemu_conf.h | 2 +- src/qemu/qemu_driver.c | 38 +++++++++++++++++++++++++++++++++++--- src/qemu/qemu_monitor.c | 16 ++++++++++++++++ src/qemu/qemu_monitor.h | 5 +++++ src/qemu/qemu_monitor_json.c | 6 ++++++ 7 files changed, 69 insertions(+), 6 deletions(-) diff --git a/include/libvirt/libvirt.h.in b/include/libvirt/libvirt.h.in index 260505e..b7a6922 100644 --- a/include/libvirt/libvirt.h.in +++ b/include/libvirt/libvirt.h.in @@ -1361,6 +1361,7 @@ typedef enum { typedef enum { VIR_DOMAIN_EVENT_SUSPENDED_PAUSED = 0, /* Normal suspend due to admin pause */ VIR_DOMAIN_EVENT_SUSPENDED_MIGRATED = 1, /* Suspended for offline migration */ + VIR_DOMAIN_EVENT_SUSPENDED_IOERROR = 2, /* Suspended due to a disk I/O error */ } virDomainEventSuspendedDetailType;

Re: [libvirt] Cannot enumerate physical devices with libvirt 0.7.6
by Frédéric Grelot 18 Feb '10

Hi Dave and all > have four on my test system, which I just installed. How did you > install the box, install F12, then what? Just to rule this out, did > you rebuild the RPM? I first built it from source (0.7.6), but, when the package was released in rawvirt (repo enabled in my system), I uninstalled my version ("make uninstall" in the directory where I installed it from), then installed that of rawvirt... When I started having these problems, I uninstalled / reinstalled again, but it didn't change anything. Well... you solved my problem anyway : to sort this out, I tried that again. Thus I noticed that after having uninstalled everything (yum remove + make uninstall), the "libvirtd" command still "worked" (with errors). I checked... and there was a /sbin/libvirtd, left by I-don-t-know-which install! . It was one of those last, undoubtly, since "libvirtd --version" actually returned 0.7.6... (And, of course, in the default PATH, /sbin stands before /usr/bin/...) I removed (=backuped just in case...) it, installed with yum, and it works at last! Thanks for your help, you got me to the right path... And sorry for the inconvenient of a "custom" install... However, I don't explain why this libvirtd was left there... Were the paths changed lately?

This patch fixes the problem with the tear down of the macvtap device when issuing a 'virsh destroy' by moving the tear down block past the point of killing the Qemu process. It seems necessary to loop at least once in the case of 'virsh destory' since the device seems to be busy for a while after the Qemu process has been killed. This also still properly tears down the macvtap device when the VM is 'virsh shutdown'ed or halted from inside. Signed-off-by: Stefan Berger <stefanb(a)us.ibm.com>

[libvirt] [PATCH v2 0/9] New public API for computing baseline CPU
by Jiri Denemark 17 Feb '10

Version 2 changes: - rebased (mainly for conn argument removal) - swapped array and number of elements in array parameters - fixed absolute paths in generated RPC code - added python bindings for virConnectBaselineCPU - fixed uninitialized variable in cpuDecode, which wasn't revealed by gcc :-( This series introduces a new virConnectBaselineCPU() API call for computing baseline CPU model from a set of host CPU definitions. The call accepts a list of <cpu>...</cpu> xml definitions taken from host capabilities and returns an xml description of a guest CPU which is supported by all hosts. virsh is little bit less picky and accepts a file containing host CPU definitions. It doesn't care what is outside of the <cpu/> tag, which allows for concatenating outputs of virsh capabilities from several hosts and feeding the result to virsh cpu-baseline. This series can also be found on cpu-baseline branch of git://gitorious.org/~jirka/libvirt/jirka-staging.git In practice it works like this: # virsh cpu-baseline /dev/stdin >guest-cpu <<EOF <capabilities> <host> <cpu> <arch>x86_64</arch> <model>core2duo</model> <topology sockets='1' cores='2' threads='1'/> <feature name='lahf_lm'/> <feature name='xtpr'/> <feature name='cx16'/> <feature name='tm2'/> <feature name='est'/> <feature name='vmx'/> </cpu> </host> </capabilities> <cpu> <arch>i686</arch> <model>pentiumpro</model> <topology sockets='1' cores='2' threads='1'/> <feature name='vme'/> <feature name='pse36'/> <feature name='pni'/> <feature name='monitor'/> <feature name='ssse3'/> </cpu> <cpu> <arch>x86_64</arch> <model>phenom</model> </cpu> EOF # cat guest-cpu <cpu match='exact'> <model>qemu32</model> <feature policy='require' name='monitor'/> <feature policy='require' name='pse36'/> </cpu> Jiri Denemark (9): Functions for computing baseline CPU from a set of host CPUs Implement cpuArchBaseline in generic CPU driver Implement cpuArchBaseline in x86 CPU driver virConnectBaselineCPU public API Internal driver API for virConnectBaselineCPU virConnectBaselineCPU public API implementation Wire protocol format and dispatcher for virConnectBaselineCPU Implement cpuBaseline in remote and qemu drivers cpu-baseline command for virsh daemon/remote.c | 25 +++++++ daemon/remote_dispatch_args.h | 1 + daemon/remote_dispatch_prototypes.h | 8 ++ daemon/remote_dispatch_ret.h | 1 + daemon/remote_dispatch_table.h | 5 ++ include/libvirt/libvirt.h.in | 18 +++++ python/generator.py | 1 + python/libvirt-override-api.xml | 7 ++ python/libvirt-override.c | 52 +++++++++++++++ src/cpu/cpu.c | 123 ++++++++++++++++++++++++++++++++++- src/cpu/cpu.h | 21 ++++++- src/cpu/cpu_generic.c | 104 +++++++++++++++++++++++++++++- src/cpu/cpu_x86.c | 88 ++++++++++++++++++++++++- src/driver.h | 6 ++ src/esx/esx_driver.c | 1 + src/libvirt.c | 57 ++++++++++++++++ src/libvirt_private.syms | 2 + src/libvirt_public.syms | 1 + src/lxc/lxc_driver.c | 1 + src/opennebula/one_driver.c | 1 + src/openvz/openvz_driver.c | 1 + src/phyp/phyp_driver.c | 1 + src/qemu/qemu_driver.c | 14 ++++ src/remote/remote_driver.c | 32 +++++++++ src/remote/remote_protocol.c | 22 ++++++ src/remote/remote_protocol.h | 20 ++++++ src/remote/remote_protocol.x | 18 +++++- src/test/test_driver.c | 1 + src/uml/uml_driver.c | 1 + src/vbox/vbox_tmpl.c | 1 + src/xen/xen_driver.c | 1 + tools/virsh.c | 72 ++++++++++++++++++++ tools/virsh.pod | 8 ++ 33 files changed, 709 insertions(+), 6 deletions(-)
