[libvirt] A question about create image for sheepdog
by chang liu 08 Sep '11

08 Sep '11

Hi everyone: I want to build a VM Manage System, and I use libvirt to create and delete VM. But now I has used sheepdog as the disk, but I have to create sheepdog image by hand. If I have a thousand of servers, how can I create the image? I think if I can write a API for create the sheepdog image by call the qemu-img or kvm-img? (My English is rather poor, please forgive me)

[libvirt] [PATCH 0/2] snapshot: add getName API
by Eric Blake 08 Sep '11

08 Sep '11

I know I've missed the 0.9.5 RC1 freeze, but think that this new API is worth adding, if only because I noticed that 'virsh snapshot-create dom --no-metadata' currently creates a snapshot with a generated name but then fails in attempting to express that name to the user.

[libvirt] [PATCH] Don't treat pci_system_init failure as fatal if no PCI bus is present
by Soren Hansen 08 Sep '11

08 Sep '11

Xen PV domU's have no PCI bus. node_device_udev.c calls pci_system_init which looks for /sys/bus/pci. If it does not find /sys/bus/pci (which it won't in a Xen PV domU) it returns unsuccesfully (ENOENT), which libvirt considers fatal. This makes libvirt unusable in this environment, even though there are plenty of valid virtualisation options that work there (LXC, UML, and QEmu spring to mind) https://bugzilla.redhat.com/show_bug.cgi?id=709471 Signed-off-by: Soren Hansen <soren(a)linux2go.dk> --- src/node_device/node_device_udev.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/node_device/node_device_udev.c b/src/node_device/node_device_udev.c index badf241..08ef856 100644 --- a/src/node_device/node_device_udev.c +++ b/src/node_device/node_device_udev.c @@ -1620,7 +1620,7 @@ static int udevDeviceMonitorStartup(int privileged) /* Ignore failure as non-root; udev is not as helpful in that * situation, but a non-privileged user won't benefit much * from udev in the first place. */ - if (privileged || errno != EACCES) { + if (errno != ENOENT && (privileged || errno != EACCES)) { char ebuf[256]; VIR_ERROR(_("Failed to initialize libpciaccess: %s"), virStrerror(pciret, ebuf, sizeof ebuf)); -- 1.7.5.4

[libvirt] [PATCH rfc] xml: Change virtual file names of xml documents parsed in memory
by Peter Krempa 08 Sep '11

08 Sep '11

While parsing XML strings from memory, the previous convention in libvirt was to set the virtual file name to "domain.xml" or something similar. This could potentialy trick the user into looking for a file named domain.xml on the disk in an attempt to fix the error. This patch changes these filenames to something that can't be as easily confused for a valid filename. --- For the request for comments: Shoud we use translation macros around these filename strings? It might be possible to translate these messages in something meaningful in other languages. Thanks for your comments.
