[libvirt] [PATCH 0/4] Update interface xml to match netcf 0.1.5
by Laine Stump 20 Jan '10

20 Jan '10

The first two patches make minor additions to the parsing/formatting. The 3rd is a bit more intrusive, as it switches from using virInterfaceBareDef for subordinate interfaces to recursively using a full virInterfaceDef (but with guaranteed closure due to limiting the type of subordinate interface allowed based on parent interface). The final patch updates the RNG and test files accordingly.

[libvirt] hvm/x86_64 combination not allowed
by Steve Brown 20 Jan '10

20 Jan '10

I have a VM that I am able to run using qemu form a command prompt with no problems. I want to run it from within libvirt, so I converted my qemu command to XML using 'virsh domxml-from-native ...' My problem is that my libvirt does not seem to support the x86_64 architecture, so when I try to launch the VM, the kernel won't built since it was installed on x86_64. My os container is as follows (as imported by virsh): <os> <type arch='i686' machine='pc-0.11'>hvm</type> <boot dev='hd'/> </os> However, when I try to change it to this: <os> <type arch='x86_64'>hvm</type> <boot dev='hd'/> </os> I get the following message: error: internal error os type 'hvm' & arch 'x86_64' combination is not supported I've searched for a proper command line switch to build this option into libvirt, but I have not had any success. So how do I get libvirt to support the x86_64 arch? Thanks, Steve PS: $ sudo virsh capabilities <capabilities> <host> <cpu> <arch>x86_64</arch> </cpu> <migration_features> <live/> <uri_transports> <uri_transport>tcp</uri_transport> </uri_transports> </migration_features> </host> <guest> <os_type>hvm</os_type> <arch name='i686'> <wordsize>32</wordsize> <emulator>/usr/bin/qemu</emulator> <machine>pc-0.11</machine> <machine canonical='pc-0.11'>pc</machine> <machine>pc-0.10</machine> <machine>isapc</machine> <domain type='qemu'> </domain> </arch> <features> <pae/> <nonpae/> <acpi default='on' toggle='yes'/> <apic default='on' toggle='no'/> </features> </guest> </capabilities>

[libvirt] [PATCH] logging: confirm that we want to ignore a write error
by Jim Meyering 19 Jan '10

19 Jan '10

Ignoring a write failure is a big deal, so when you do that deliberately, it's worth marking in such a way that code analyzers don't report a false positive. Until a year or so ago, people thought using (void) would be enough. But newer gcc warns in spite of that (for functions marked with the warn_unused_result attribute), so now we use the ignore_value function from gnulib. A coverity warning prompted the change below, but if we declare saferead with the warn_unused_result attribute, gcc would, too. >From 62d2c7f69608407afa9a4bf38f0d29ea3eec88f5 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Mon, 18 Jan 2010 11:51:01 +0100 Subject: [PATCH] logging: confirm that we want to ignore a write error * src/util/logging.c (virLogMessage): Include "ignore-value.h".

[libvirt] [PATCH v2 0/2] Block assignment of PCI devices below non-ACS capable switch
by Jiri Denemark 19 Jan '10

19 Jan '10

This is a patchset for blocking assignment of PCI devices below non-ACS capable switch. In case user still wants to assign such device even though it might not be safe, she can specify 'relaxed_acs_check = 1' in qemu.conf Special thanks to Chris L. who created a standalone program the PCI check. This code is a port of that check to libvirt. Changes in version 2: - permissive attribute for <hostdev> was removed - new 'relaxed_acs_check' config option in qemu.conf for relaxing the check Jiri Denemark (2): Tests for ACS in PCIe switches Use pciDeviceIsAssignable in qemu driver src/libvirt_private.syms | 1 + src/qemu/libvirtd_qemu.aug | 1 + src/qemu/qemu.conf | 6 ++ src/qemu/qemu_conf.c | 4 + src/qemu/qemu_conf.h | 2 + src/qemu/qemu_driver.c | 6 ++- src/qemu/test_libvirtd_qemu.aug | 6 ++- src/util/pci.c | 151 +++++++++++++++++++++++++++++++++++++++ src/util/pci.h | 4 + 9 files changed, 179 insertions(+), 2 deletions(-)

[libvirt] [PATCH] Make all bitfields unsigned ints to avoid unexpected values in casts
by Daniel P. Berrange 19 Jan '10

19 Jan '10

The 'int virInterfaceIsActive()' method was directly returning the value of the 'int active:1' bitfield in virIntefaceDefPtr. A bitfield with a signed integer, will hold the values 0 and -1, not 0 and +1 as might be expected. This meant that virInterfaceIsActive() was always returning -1 when the interface was active, not +1 & thus all callers thought an error had occurred. To protect against this kind of mistake again, change all bitfields to be unsigned ints * daemon/libvirtd.h, src/conf/domain_conf.h, src/conf/interface_conf.h, src/conf/network_conf.h: Change bitfields to unsigned int. --- daemon/libvirtd.h | 14 +++++++------- src/conf/domain_conf.h | 14 +++++++------- src/conf/interface_conf.h | 2 +- src/conf/network_conf.h | 2 +- 4 files changed, 16 insertions(+), 16 deletions(-) diff --git a/daemon/libvirtd.h b/daemon/libvirtd.h index 2f647f3..a7591fc 100644 --- a/daemon/libvirtd.h +++ b/daemon/libvirtd.h @@ -175,9 +175,9 @@ struct qemud_client { int fd; int watch; - int readonly:1; - int closing:1; - int domain_events_registered:1; + unsigned int readonly :1; + unsigned int closing :1; + unsigned int domain_events_registered :1; struct sockaddr_storage addr; socklen_t addrlen; @@ -185,7 +185,7 @@ struct qemud_client { int type; /* qemud_sock_type */ gnutls_session_t tlssession; int auth; - int handshake : 1; /* If we're in progress for TLS handshake */ + unsigned int handshake :1; /* If we're in progress for TLS handshake */ #if HAVE_SASL sasl_conn_t *saslconn; int saslSSF; @@ -244,9 +244,9 @@ struct qemud_socket { struct qemud_worker { pthread_t thread; - int hasThread :1; - int processingCall :1; - int quitRequest : 1; + unsigned int hasThread :1; + unsigned int processingCall :1; + unsigned int quitRequest :1; /* back-pointer to our server */ struct qemud_server *server; diff --git a/src/conf/domain_conf.h b/src/conf/domain_conf.h index 1413273..7be090d 100644 --- a/src/conf/domain_conf.h +++ b/src/conf/domain_conf.h @@ -400,8 +400,8 @@ enum virDomainVideoType { typedef struct _virDomainVideoAccelDef virDomainVideoAccelDef; typedef virDomainVideoAccelDef *virDomainVideoAccelDefPtr; struct _virDomainVideoAccelDef { - int support3d : 1; - int support2d : 1; + unsigned int support3d :1; + unsigned int support2d :1; }; @@ -432,7 +432,7 @@ struct _virDomainGraphicsDef { union { struct { int port; - int autoport : 1; + unsigned int autoport :1; char *listenAddr; char *keymap; char *passwd; @@ -445,13 +445,13 @@ struct _virDomainGraphicsDef { struct { int port; char *listenAddr; - int autoport : 1; - int replaceUser : 1; - int multiUser : 1; + unsigned int autoport :1; + unsigned int replaceUser :1; + unsigned int multiUser :1; } rdp; struct { char *display; - int fullscreen : 1; + unsigned int fullscreen :1; } desktop; } data; }; diff --git a/src/conf/interface_conf.h b/src/conf/interface_conf.h index 2683eee..5b201d3 100644 --- a/src/conf/interface_conf.h +++ b/src/conf/interface_conf.h @@ -170,7 +170,7 @@ typedef virInterfaceObj *virInterfaceObjPtr; struct _virInterfaceObj { virMutex lock; - int active:1; /* 1 if interface is active (up) */ + unsigned int active:1; /* 1 if interface is active (up) */ virInterfaceDefPtr def; /* The interface definition */ }; diff --git a/src/conf/network_conf.h b/src/conf/network_conf.h index 0214d1a..9e50659 100644 --- a/src/conf/network_conf.h +++ b/src/conf/network_conf.h @@ -65,7 +65,7 @@ struct _virNetworkDef { char *bridge; /* Name of bridge device */ char *domain; unsigned long delay; /* Bridge forward delay (ms) */ - int stp : 1; /* Spanning tree protocol */ + unsigned int stp :1; /* Spanning tree protocol */ int forwardType; /* One of virNetworkForwardType constants */ char *forwardDev; /* Destination device for forwarding */ -- 1.6.5.2

[libvirt] [PATCH] Take disabled/forced CPU features into account
by Jiri Denemark 19 Jan '10

19 Jan '10

When comparing x86 CPUs, features with 'disabled' policy were mistakenly required to be supported by the host CPU. Likewise, features with 'force' policy which were supported by host CPU would make CPUs incompatible if 'strict' match was used by guest CPU. This patch fixes both issues.

[libvirt] [PATCH v2] Implement CPU topology support for QEMU driver
by Jiri Denemark 19 Jan '10

19 Jan '10

QEMU's command line equivalent for the following domain XML fragment <vcpus>2</vcpus> <cpu ...> ... <topology sockets='1' cores='2', threads='1'/> </cpu> is -smp 2,sockets=1,cores=2,threads=1 This syntax was introduced in QEMU-0.12. Version 2 changes: - -smp argument build split into a separate function - always add ",sockets=S,cores=C,threads=T" to -smp if qemu supports it - use qemuParseCommandLineKeywords for command line parsing Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com> --- src/qemu/qemu_conf.c | 159 +++++++++++++++++++++++++++++++++++++++++++++----- src/qemu/qemu_conf.h | 3 +- 2 files changed, 145 insertions(+), 17 deletions(-) diff --git a/src/qemu/qemu_conf.c b/src/qemu/qemu_conf.c index 9f35217..09bbf7a 100644 --- a/src/qemu/qemu_conf.c +++ b/src/qemu/qemu_conf.c @@ -1,7 +1,7 @@ /* * qemu_conf.c: QEMU configuration management * - * Copyright (C) 2006, 2007, 2008, 2009 Red Hat, Inc. + * Copyright (C) 2006, 2007, 2008, 2009, 2010 Red Hat, Inc. * Copyright (C) 2006 Daniel P.
