[libvirt] XML for the "boot=on" option
by Shi Jin 20 Jan '10

20 Jan '10

Hi, there, In order to install windows 2008 using the virtio driver, I had to modify the KVM command to include the boot=on option like: -drive file=<path>/virtioWin08.raw,if=virtio,index=0,boot=on However, I haven't been able to find a corresponding libvirt XML element that can enable this "boot=on" option. Is there a way to do this? Thanks a lot. -- Shi Jin, PhD

[libvirt] [PATCH] Fix QEMU driver custom domain status XML extensions
by Daniel P. Berrange 20 Jan '10

20 Jan '10

Invoking the virConnectGetCapabilities() method causes the QEMU driver to rebuild its internal capabilities object. Unfortunately it was forgetting to register the custom domain status XML hooks again. To avoid this kind of error in the future, the code which builds capabilities is refactored into one single method, which can be called from all locations, ensuring reliable rebuilds. * src/qemu/qemu_driver.c: Fix rebuilding of capabilities XML and guarentee it is always consistent --- src/qemu/qemu_driver.c | 110 +++++++++++++++++++++++------------------------- 1 files changed, 53 insertions(+), 57 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 2d80774..9a3ddfb 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -892,34 +892,6 @@ qemuReconnectDomains(struct qemud_driver *driver) static int -qemudSecurityCapsInit(virSecurityDriverPtr secdrv, - virCapsPtr caps) -{ - const char *doi, *model; - - doi = virSecurityDriverGetDOI(secdrv); - model = virSecurityDriverGetModel(secdrv); - - caps->host.secModel.model = strdup(model); - if (!caps->host.secModel.model) { - virReportOOMError(NULL); - return -1; - } - - caps->host.secModel.doi = strdup(doi); - if (!caps->host.secModel.doi) { - virReportOOMError(NULL); - return -1; - } - - VIR_DEBUG("Initialized caps for security driver \"%s\" with " - "DOI \"%s\"", model, doi); - - return 0; -} - - -static int qemudSecurityInit(struct qemud_driver *qemud_drv) { int ret; @@ -940,15 +912,52 @@ qemudSecurityInit(struct qemud_driver *qemud_drv) qemud_drv->securityDriver = security_drv; VIR_INFO("Initialized security driver %s", security_drv->name); - - /* - * Add security policy host caps now that the security driver is - * initialized. - */ - return qemudSecurityCapsInit(security_drv, qemud_drv->caps); + return 0; } +static virCapsPtr +qemuCreateCapabilities(virCapsPtr oldcaps, + virSecurityDriverPtr secDriver) +{ + virCapsPtr caps; + + /* Basic host arch / guest machine capabilities */ + if (!(caps = qemudCapsInit(oldcaps))) { + virReportOOMError(NULL); + return NULL; + } + + /* Domain XML parser hooks */ + caps->privateDataAllocFunc = qemuDomainObjPrivateAlloc; + caps->privateDataFreeFunc = qemuDomainObjPrivateFree; + caps->privateDataXMLFormat = qemuDomainObjPrivateXMLFormat; + caps->privateDataXMLParse = qemuDomainObjPrivateXMLParse; + + + /* Security driver data */ + if (secDriver) { + const char *doi, *model; + + doi = virSecurityDriverGetDOI(secDriver); + model = virSecurityDriverGetModel(secDriver); + + if (!(caps->host.secModel.model = strdup(model))) + goto no_memory; + if (!(caps->host.secModel.doi = strdup(doi))) + goto no_memory; + + VIR_DEBUG("Initialized caps for security driver \"%s\" with " + "DOI \"%s\"", model, doi); + } + + return caps; + +no_memory: + virReportOOMError(NULL); + virCapabilitiesFree(caps); + return NULL; +} /** * qemudStartup: @@ -1074,13 +1083,12 @@ qemudStartup(int privileged) { virStrerror(-rc, buf, sizeof(buf))); } - if ((qemu_driver->caps = qemudCapsInit(NULL)) == NULL) - goto out_of_memory; + if (qemudSecurityInit(qemu_driver) < 0) + goto error; - qemu_driver->caps->privateDataAllocFunc = qemuDomainObjPrivateAlloc; - qemu_driver->caps->privateDataFreeFunc = qemuDomainObjPrivateFree; - qemu_driver->caps->privateDataXMLFormat = qemuDomainObjPrivateXMLFormat; - qemu_driver->caps->privateDataXMLParse = qemuDomainObjPrivateXMLParse; + if ((qemu_driver->caps = qemuCreateCapabilities(NULL, + qemu_driver->securityDriver)) == NULL) + goto error; if ((qemu_driver->activePciHostdevs = pciDeviceListNew(NULL)) == NULL) goto error; @@ -1104,10 +1112,6 @@ qemudStartup(int privileged) { } } - if (qemudSecurityInit(qemu_driver) < 0) { - goto error; - } - /* If hugetlbfs is present, then we need to create a sub-directory within * it, since we can't assume the root mount point has permissions that * will let our spawned QEMU instances use it. @@ -3255,15 +3259,12 @@ static char *qemudGetCapabilities(virConnectPtr conn) { char *xml = NULL; qemuDriverLock(driver); - if ((caps = qemudCapsInit(qemu_driver->caps)) == NULL) - goto no_memory; - caps->privateDataAllocFunc = qemuDomainObjPrivateAlloc; - caps->privateDataFreeFunc = qemuDomainObjPrivateFree; - - if (qemu_driver->securityDriver && - qemudSecurityCapsInit(qemu_driver->securityDriver, caps) < 0) - goto no_memory; + if ((caps = qemuCreateCapabilities(qemu_driver->caps, + qemu_driver->securityDriver)) == NULL) { + virCapabilitiesFree(caps); + goto cleanup; + } virCapabilitiesFree(qemu_driver->caps); qemu_driver->caps = caps; @@ -3275,11 +3276,6 @@ cleanup: qemuDriverUnlock(driver); return xml; - -no_memory: - virCapabilitiesFree(caps); - virReportOOMError(conn); - goto cleanup; } -- 1.6.5.2

[libvirt] Website contains outdated information about remote limitations
by Matthias Bolte 20 Jan '10

20 Jan '10

http://www.libvirt.org/remote.html#Remote_limitations says: Limitations * Remote storage: To be fully useful, particularly for creating new domains, it should be possible to enumerate and provision storage on the remote machine. This is currently in the design phase. * Migration: We expect libvirt will support migration, and obviously remote support is what makes migration worthwhile. This is also in the design phase. Issues to discuss include which path the migration data should follow (eg. client to client direct, or client to server to client) and security. IMHO this is outdated information, because libvirt supports both features now. So both should be removed from the website as they could misinform newbies. Matthias

[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

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
