[libvirt] [PATCH] macvtap teardown rework
by Stefan Berger 18 Feb '10

18 Feb '10

I have reworked and simplified the teardown of the macvtap device. Basically all devices with the same MAC address and link device are kept alive and not attempted to be torn down. If a macvtap device linked to a physical interface with a certain MAC address 'M' is to be created it will automatically fail if the interface is 'up'ed and another macvtap with the same properties (MAC addr 'M', link dev) happens to be 'up'. This will prevent the VM from starting or the device from being attached to a running VM. Stale interfaces are assumed to be there for some reason and not stem from libvirt. In the VM shutdown path I am assuming that an interface name is always available so that if the device type is DIRECT it can be torn down using its name.

18 Feb '10

Hi, I have some doubts regarding libvirt XML format. Can anyone please let me know in detail, what is <source> and <target> tags in the libvirt XML format? Can I put '/' in the <target> tag or are there any exceptions if I put '/' in that? Please let me know. Regards, Srikanth.

[libvirt] [PATCH] Automatically pause QEMU guests when an error occurs
by Daniel P. Berrange 17 Feb '10

17 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;
