[libvirt] [PATCH] Don't attempt to read from a stream if it is closed
by Daniel P. Berrange 16 Aug '11

16 Aug '11

From: "Daniel P. Berrange" <berrange(a)redhat.com> The I/O event callback processes incoming packets first, and then does outgoing packets. If the incoming packet caused the stream to close, then the attempt to process outgoing data resulted in an error. This caused libvirt to then send an error back to the client, but the stream had already been stopped. This confused the client since it sees 2 error events. * daemon/stream.c: Don't attempt read if stream is closed --- daemon/stream.c | 10 +++++++++- 1 files changed, 9 insertions(+), 1 deletions(-) diff --git a/daemon/stream.c b/daemon/stream.c index 7dd9ae7..7d2b367 100644 --- a/daemon/stream.c +++ b/daemon/stream.c @@ -678,7 +678,15 @@ daemonStreamHandleRead(virNetServerClientPtr client, size_t bufferLen = VIR_NET_MESSAGE_PAYLOAD_MAX; int ret; - VIR_DEBUG("client=%p, stream=%p", client, stream); + VIR_DEBUG("client=%p, stream=%p tx=%d closed=%d", + client, stream, stream->tx, stream->closed); + + /* We might have had an event pending before we shut + * down the stream, so if we're marked as closed, + * then do nothing + */ + if (stream->closed) + return 0; /* Shouldn't ever be called unless we're marked able to * transmit, but doesn't hurt to check */ -- 1.7.6

[libvirt] [RFC] Host CPU passthrough
by Jiri Denemark 16 Aug '11

16 Aug '11

Hi, AFAIK this topic is not new but I think we still do not have a good solution for it. Libvirt already supports specifying what CPU and its features a guest should see but imagine one wants to run a guest on the best possible CPU. The current way is to copy the <cpu> element from capabilities XML into domain XML. This approach is fine since it provides reproducible environment and such domain can even be migrated to a different host. But the CPU shown provided to a guest is not the same as the real host CPU. It's based on a model which doesn't reflect all aspects of real CPUs. Ideally, we would model everything but that's quite complicated and may need updating anytime a new CPU is introduced. I think we should add a possibility to passthrough host CPU into a domain no matter what the CPU looks like. Domains configured in such a way will not be allowed to be migrated since we cannot guarantee the same CPU on destination host but they would be able to see the real CPU. Another benefit is that a single XML configuration would work on any CPU without modifications. Since possible issues with such domains will be harder to debug we can mark them as tainted just like we do if someone calls qemu monitor commands directly. I'm not sure what XML representation makes the most sense so I'll mention several options which I'm thinking about: - "host" ("native", "passthrough", whatever) special model; same name space as real CPU models, I don't like this too much: <cpu match='exact'> <model>host</model> </cpu> - "host" match policy; has nice first-look semantics that the guest CPU matches host's but doesn't play very nice with the defined semantics of "match" attribute: <cpu match='host'/> - new "mode" attribute; IMHO the best one, similar to what we have for SMBIOS: <cpu mode='host'/> vs. <cpu mode='custom' match='...'> <model>...</model. ... </cpu> What do you think?

[libvirt] Bug - libvirt persists on having dnsmasq
by Zdenek Styblik 16 Aug '11

16 Aug '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I've noticed libvirt is persisting to have dnsmasq present and use it. Version of libvirt in question is 0.9.4. There is no dnsmasq present on the Host during libvirt compilation, yet it seems to me ./configure wrongfully finds one: ~~~ SNIP ~~~ configure:46087: checking for dnsmasq configure:46119: result: dnsmasq ~~~ SNIP ~~~ shouldn't there be "result: no"? As far as I remember - no dnsmasq present during compilation, no usage of it later. However I might have missed something - change in behavior, requirements etc. This is possible. Still, if required "component" is missing, I say compilation resp. configure should fail. And this of course breaks things later on: ~~~ SNIP ~~~ virsh # net-start virtnet01 error: Failed to start network virtnet01 error: Cannot find 'dnsmasq' in path: No such file or directory ~~~ SNIP ~~~ and there is no DHCP defined for 'virtnet01' thus there is no reason to bring dnsmasq in. Neither can be new network created and started via virt-manager.

[libvirt] [PATCH] Fix race condition in abort of stream
by Daniel P. Berrange 16 Aug '11

16 Aug '11

From: "Daniel P. Berrange" <berrange(a)redhat.com> If a stream gets a server initiated abort, the client may still send an abort request before it receives the server side abort. This causes the server to send back another abort for the stream. Since the protocol defines that abort is the last thing to be sent, the client gets confused by this second abort from the server. If the stream is already shutdown, just drop any client requested abort, rather than sending back another message. This fixes the regression from previous versions. Tested as follows In one virsh session virsh # start foo virsh # console foo In other virsh session virsh # destroy foo The first virsh session should be able to continue issues commands without error. Prior to this patch it saw virsh # list error: Failed to list active domains error: An error occurred, but the cause is unknown virsh # list error: Failed to list active domains error: no call waiting for reply with prog 536903814 vers 1 serial 9 * src/rpc/virnetserverprogram.c: Drop abort requests for streams which no longer exist --- src/rpc/virnetserverprogram.c | 25 ++++++++----------------- 1 files changed, 8 insertions(+), 17 deletions(-) diff --git a/src/rpc/virnetserverprogram.c b/src/rpc/virnetserverprogram.c index 63a6b6d..ca80ae0 100644 --- a/src/rpc/virnetserverprogram.c +++ b/src/rpc/virnetserverprogram.c @@ -257,23 +257,14 @@ int virNetServerProgramDispatch(virNetServerProgramPtr prog, * stream packets after we closed down a stream.

[libvirt] [PATCH 0/4 v3] macvtap: Support for sending port profile message for a SRIOV VF to its PF
by Roopa Prabhu 16 Aug '11

16 Aug '11

This patch tries to fix getPhysFn in macvtap.c to get the physical function(PF) of the direct attach interface, if the interface is a SR-IOV VF. It moves some of the sriov pci device handling code from node_device_driver to src/util/pci.[ch]. This patch series implements the following 01/4 - pci: Move some pci sriov helper code out of node device driver to util/pci 02/4 - pci: Add helper functions for sriov devices 03/4 - interface: Add functions to get sriov PF/VF relationship of a net interface 04/4 - macvtap: Fix getPhysfn to get the PF of a direct attach network interface Changelog: ---------- v1: RFC patch introduced new functions to get PF/VF relationship of SRIOV net devices by comparing PF/VF sysfs device links. Also mentioned the existance of some related code in node_device_driver. The feedback was to move and use the node_device_driver code v2: Moves sriov get_physical_function and get_virtual_functions from node_device_driver to src/util/pci*. And reworks the rest of the patches around the new code. v3: Incorporated Stefan Berger's comments. Fixed indentation errors shown by 'make syntax-check'.

[libvirt] [PATCH v3] daemon: Add early libvirtd start verbose errors.
by Peter Krempa 16 Aug '11

16 Aug '11

Early errors during start of libvirtd didn't have an error reporting mechanism and caused libvirtd to exit silently (only the return value indicated an error). Libvirt logging is initialized very early using enviroment variables and the internal error reporting API is used to report early errors. v2 changes: - print errors unconditionaly before logging starts - fix message to US spelling v2.5 changes: - initialize logging from enviroment - log all early errors using VIR_ERROR v3 changes: - move virSetLogFromEnv() after virInitialize() fixes: https://bugzilla.redhat.com/show_bug.cgi?id=728654 --- On 08/12/2011 12:09 PM, Daniel P.
