[libvirt] [PATCH] Allow NULL mac address in virGetInterface.
by Laine Stump 03 Nov '09

03 Nov '09

There are places where an interface will not have a mac address, and netcf returns this as a NULL pointer rather than a pointer to an empty string. Rather than checking for this all over the place in libvirt, just save it in the virInterface object as an empty string. --- src/datatypes.c | 7 ++++++- 1 files changed, 6 insertions(+), 1 deletions(-) diff --git a/src/datatypes.c b/src/datatypes.c index 89ad309..ecefc59 100644 --- a/src/datatypes.c +++ b/src/datatypes.c @@ -588,10 +588,15 @@ virInterfacePtr virGetInterface(virConnectPtr conn, const char *name, const char *mac) { virInterfacePtr ret = NULL; - if ((!VIR_IS_CONNECT(conn)) || (name == NULL) || (mac == NULL)) { + if ((!VIR_IS_CONNECT(conn)) || (name == NULL)) { virLibConnError(NULL, VIR_ERR_INVALID_ARG, __FUNCTION__); return(NULL); } + + /* a NULL mac from caller is okay.

[libvirt] [PATCH] Remove redundant virFileDeletePID() call
by Chris Lalancette 03 Nov '09

03 Nov '09

qemudShutdownVMDaemon() calls qemudRemoveDomainStatus(), which then calls virFileDeletePID(). qemudShutdownVMDaemon() then unnecessarily calls virFileDeletePID() again. Remove this second usage of it, and also slightly refactor qemudRemoveDomainStatus() to VIR_WARN appropriate error messages.

[libvirt] [PATCH 00/21] Rewrite the QEMU monitor handling
by Daniel P. Berrange 03 Nov '09

03 Nov '09

This patch series rewrites the QEMU monitor handling almost completely. The key theme here is to move from a totally synchronous way of interacting with the monitor, to a totally asynchronous way. This allows us to handle receipt & dispatch of asychronous events from QEMU. For example a notification of a disk-full error, or VM state change. In the process of doing this re-factoring I have also dropped in basic support/infrastructure for the JSON based monitor. The basic JSON parsing/formatting is working, but this needs to wait until QEMU community finalize their monitor syntax for the new commands & what args they accept. Daniel

[libvirt] cannot get virt-manager to see VM
by Gerry Reno 02 Nov '09

02 Nov '09

I used qemu-img to create a raw image. I then create an xml file with no uuid but a new name and new mac address. Then I did a 'virsh define NEW.img'. When I do a 'virsh list --all' the new VM is there but shut_off. But this new machine does not appear in virt-manager. What do I need to do to get the new machine to appear in the list of machines in virt-manager? I want to start this machine using virt-manager. This is on F11 with libvirt 0.6.2. -Gerry

[libvirt] [PATCH] ESX: Don't automatically follow redirects.
by Matthias Bolte 02 Nov '09

02 Nov '09

The default transport for the VI API is HTTPS. If the server redirects from HTTPS to HTTP the driver would silently follow that redirection. The user assumes to communicate with the server over a secure transport but isn't. This patch disables automatical redirection following. The driver reports an error if the server tries to redirect. * src/esx/esx_vi.c: refactor the call to curl_easy_perform() into a function and do error handling there, disable automatical redirection following for curl * src/esx/esx_vi.h: change the type of responseCode to int --- src/esx/esx_vi.c | 166 +++++++++++++++++++++++++++--------------------------- src/esx/esx_vi.h | 2 +- 2 files changed, 84 insertions(+), 84 deletions(-) diff --git a/src/esx/esx_vi.c b/src/esx/esx_vi.c index dc51e20..bcf110f 100644 --- a/src/esx/esx_vi.c +++ b/src/esx/esx_vi.c @@ -216,6 +216,68 @@ esxVI_CURL_Debug(CURL *curl ATTRIBUTE_UNUSED, curl_infotype type, } #endif +static int +esxVI_CURL_Perform(virConnectPtr conn, esxVI_Context *ctx, const char *url) +{ + CURLcode errorCode;

[libvirt] [patch] Add openvzDomainSetMemoryInternal

Hi all, This patch is to set KMEMSIZE for OpenVZ.

[libvirt] Don't use private struct member names of in6_addr

__in6_u.__u6_addr16 is the private name for this struct member, s6_addr16 is the public one. Our buildserver revealed this problem, because for some reason the internal names are missing the __ prefix there. Matthias

[libvirt] Remaining interface state reporting issue - bond options
by Laine Stump 02 Nov '09

02 Nov '09

With the patches I sent to netcf-devel last night, along with lutter's (or DV's, take your pick ;-) netcf patch to eliminate the segfault, my patches for reporting interface info now pass make check with no errors. I believe lutter will be making a netcf release tomorrow or so, after he gets back on solid ground. There is one issue left that I'm unsure what to do about - while the xml returned from netcf for bond interfaces does list all the slave interfaces of the bond and their types (and any required info for that type), the parser for bond info in libvirt requires either an miimon or arpmode node inside the bond, eg: <interface type="bond" name="bond0"> <bond> <miimon freq="100" updelay="10" carrier="ioctl"/> <interface type="ethernet" name="eth1"/> <interface type="ethernet" name="eth0"/> </bond> </interface> I haven't been able to find a source of this information yet and, while it may be useful, I don't see it as necessary. Once again I'm proposing that we make these optional in the XML, such that this would be acceptable: <interface type="bond" name="bond0"> <bond> <interface type="ethernet" name="eth1"/> <interface type="ethernet" name="eth0"/> </bond> </interface> Once we do that, the netcf-reported state of all 4 supported interface types (ethernet, bridge, vlan, bond) will pass libvirt's parsing test.

[libvirt] Add support for qemu's guestfwd
by Matthew Booth 02 Nov '09

02 Nov '09

This series adds support for a vmchannel using qemu's guestfwd. I'll be following up with support for virtio-serial and RHEL5's vmchannel. A vmchannel is specified as: <vmchannel type='pipe'> <source path='/tmp/vmchannel'/> <target type='guestfwd' address='10.0.2.1' port='4600'/> </vmchannel> There are a couple of minor complications. Firstly, the existing chrdev structure assumes that all front-ends take only a port. There's a bit of code churn adding a second union to this struct to allow for different data for different backends. Secondly, it turns out that the existing syntax for character devices doesn't really work for guestfwd. Specifically it won't allow common options to be added. This is fixed in qemu git with the new -chardev syntax. Consequently, this patch only adds support for guestfwd using -chardev. We add detection for -chardev, and a new internal utility function to output -chardev command lines for all existing character device backends. Matt
