[libvirt] [PATCH] esx: Correctly disable HTTP Expect header usage of libcurl
by Matthias Bolte 22 Feb '12

22 Feb '12

Adding "Expect:" to the header list stops libcurl from sending a Expect header at all. Before, a dummy Expect header was added that might confuse HTTP proxies and result in HTTP error code 417 being reported. --- src/esx/esx_vi.c | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/src/esx/esx_vi.c b/src/esx/esx_vi.c index 14ad50a..6004aac 100644 --- a/src/esx/esx_vi.c +++ b/src/esx/esx_vi.c @@ -293,14 +293,14 @@ esxVI_CURL_Connect(esxVI_CURL *curl, esxUtil_ParsedUri *parsedUri) "Content-Type: text/xml; charset=UTF-8"); /* - * Add a dummy expect header to stop CURL from waiting for a response code + * Add an empty expect header to stop CURL from waiting for a response code * 100 (Continue) from the server before continuing the POST operation. * Waiting for this response would slowdown each communication with the * server by approx. 2 sec, because the server doesn't send the expected * 100 (Continue) response and the wait times out resulting in wasting * approx. 2 sec per POST operation. */ - curl->headers = curl_slist_append(curl->headers, "Expect: nothing"); + curl->headers = curl_slist_append(curl->headers, "Expect:"); if (curl->headers == NULL) { ESX_VI_ERROR(VIR_ERR_INTERNAL_ERROR, "%s", -- 1.7.4.1

[libvirt] [PATCH 0/6] (informational) conf support for <interface type='hostdev'>
by Laine Stump 22 Feb '12

22 Feb '12

This series of patches enhances the domain parser/formatter code to support a sort of "intelligent hostdev", i.e. PCI passthrough where device-type specific initialization is done prior to assigning the device to the guest, in particular to allow setting the MAC address and do 802.1QbX setup for network devices. Rather than adding all of the device-type specific config to <hostdev>, I accomplish this through adding a new type of <interface> element, type='hostdev'. When an interface is type='hostdev' the following is changed: * in the toplevel device, the managed attribute can be specified (with identical results as when it's specified in a <hostdev> * The <source> element can specify a pci address or usb address, just as can be done in <hostdev>. One notable difference is that the type of the address is specified directly in the source <address> element, rather than as an attribute of the toplevel device (that's how it's done for <hostdev>, but for <interface>, the toplevel element's type attribute is already used). These patches include only the parser/formatter, test (for domainschematest, and qemuxml2xmltest only), and doc changes; they still need to be hooked into the domain's device lists (a type=hostdev interface will reside in both the interface list (for configuration and memory management) and hostdev list (for attach/detach, and tracking of which devices are assigned)). I don't intend to push these patches until that part is also done, but some other people are doing work that depends on the changes to config format and data structures, so I'm sending these patches now both to unblock them, as well as to get feedback from everyone else on what needs to be changed. The first 4 patches are just setup for the real new code - they reorder and refactor existing code to allow greater re-use of existing code and easier plugin of the new code. Patch 5/6 is just a couple of lines, and patch 6/6 provides the new functionality.

[libvirt] Network not Persistent
by Shradha Shah 22 Feb '12

22 Feb '12

Hello All, I am currently working on patches for PCI-passthrough of SRIOV VF's and I am facing an issue with the network definition not being persistent. I am using a new forward mode = hostdev and the network xml is as follows: <network> <name>pci-passthrough-network</name> <uuid>81ff0d90-c91e-6742-64da-4a736edb9a8f</uuid> <forward mode="hostdev"> <pf dev="eth2"/> </forward> </network> Command line used is: # virsh net-define pci_passthrough_network.xml The network is defined successfully and I can use it at this point. But if I restart libvirt after defining the above network, I lose the network definition. After restart libvirt does not possess any knowledge of the above network. This does not happen when I use forward mode="bridge". I have cross referenced the function call path of networkDefine for both the forwarding modes and I can't seem to find the problem. Is there some function I am missing? May I ask for your help to solve this issue? Many Thanks, Regards, Shradha Shah

[libvirt] [Bug] [vbox-driver] attach-device
by Gravok 21 Feb '12

21 Feb '12

Hi, using the version from git I can't attach devices to my domain (using attach-device) neither using the virsh or a language binding. In both cases it throws a OutOfMemory exception. It gets thrown in vbox_tmpl.c:5340, although I got 7gb of RAM left. Am I doing something wrong, or is this a bug ? Thanks ! -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

am pleased to announce that a new release of the libvirt-glib package, version 0.0.4 is now available from ftp://libvirt.org/libvirt/glib/ The packages are GPG signed with Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) New in this release: - Require libvirt >= 0.9.10 - Fix error after finishing a stream - Use G_PARAM_STATIC_STRINGS - Add config for readonly disks - Add config for description/metadata - Fix type when creating storage volumes - Remove some bogus g_error usage - Import GNULIB's compiler warning flags support & fix problems - Add API for resizing storage volumes - Add API to check if a domain is saved - Add config for disk cache method - Add APIs to get node information - Add flags for deleting domains libvirt-glib comprises three distinct libraries: - libvirt-glib - Integrate with the GLib event loop and error handling - libvirt-gconfig - Representation of libvirt XML documents as GObjects - libvirt-gobject - Mapping of libvirt APIs into the GObject type system NB: While libvirt aims to be API/ABI stable, for the first few releases, we are *NOT* guaranteeing that libvirt-glib libraries are API/ABI stable. ABI stability will only be guaranteed once the bulk of the APIs have been fleshed out and proved in non-trivial application usage. We anticipate this will be within the next 6 months in order to line up with Fedora 17. Follow up comments about libvirt-glib should be directed to the regular libvir-list redhat com development list. Thanks to all the people involved in contributing to this release.
