[libvirt] libvirt_lxc start problem when selinux enbale

Hi，all： the problem came out when selinux was enforced in targeted+MCS I start lxc through virsh――“virsh -c lxc:/// start instance-00004bd6” 1.

by yue

hi,all i have 2 questions. both is related to spice usb redirect. 1. if i can control RW perm of usb device which is producted via spice ? in order to control user's rw operation in guestVM . 2.if user have several usbs, and plug them at the same time when using spice client. if i can control which usb(s) can be accessed by user in guestVM? thanks

[libvirt] [PATCH v5 1/2] Add NVRAM device

by Li Zhang

From: Li Zhang <zhlcindy(a)linux.vnet.ibm.com> For pSeries guest in QEMU, NVRAM is one kind of spapr-vio device. Users are allowed to specify spapr-vio devices'address. But NVRAM is not supported in libvirt. So this patch is to add NVRAM device to allow users to specify its address. In QEMU, NVRAM device's address is specified by "-global spapr-nvram.reg=xxxxx". In libvirt, XML file is defined as the following: <nvram> <address type='spapr-vio' reg='0x3000'/> </nvram> Signed-off-by: Li Zhang <zhlcindy(a)linux.vnet.ibm.com> --- v5 -> v4: * Add NVRAM capability suggested by Osier Yang. * Define macros for VIO device address. * Define qemuBuildNVRAMDevStr as static func. * Correct several error messages. * Add xml2xml test case v4 -> v3: * Seperate NVRAM definition from qemu command line parser. v3 -> v2: * Add NVRAM in domaincommon.rng and formatdomain.xml.in suggested by Daniel P.Berrange * Add NVRAM test cases suggested by Daniel P.Berrange * Remove nvram allocation when it is not specified suggested by Daniel P.Berrange * Add several error reports suggested by Daniel P.Berrange v2 -> v1: * Add NVRAM parameters parsing in qemuParseCommandLine docs/formatdomain.html.in | 35 +++++++++++++++++++ docs/schemas/domaincommon.rng | 10 ++++++ src/conf/domain_conf.c | 81 +++++++++++++++++++++++++++++++++++++++++++ src/conf/domain_conf.h | 10 ++++++ 4 files changed, 136 insertions(+) diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index 0cc56d9..4a7a66f 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -4502,6 +4502,41 @@ qemu-kvm -net nic,model=? /dev/null </dd> </dl> + <h4><a name="elementsNVRAM">NVRAM device</a></h4> + + One NVRAM device is always added to pSeries guests on PPC64. + And on PPC64, NVRAM devices' address type are VIO which + allows users to change.<code>nvram</code> element in XML file + is provided to specify its address. + Currently, libvirt only considers configuration for pSeries guests. + + + Example: usage of NVRAM configuration + +<pre> + ... + <devices> + <nvram> + <address type='spapr-vio' reg='0x3000'/> + </nvram> + </devices> + ... +</pre> + <dl> + <dt><code>spapr-vio</code></dt> + <dd> + + VIO device address type, this is only for PPC64. + + </dd> + <dt><code>reg</code></dt> + <dd> + + Devices' address + + </dd> + </dl> + <h3><a name="seclabel">Security label</a></h3> diff --git a/docs/schemas/domaincommon.rng b/docs/schemas/domaincommon.rng index 3976b82..86ef540 100644 --- a/docs/schemas/domaincommon.rng +++ b/docs/schemas/domaincommon.rng @@ -2793,6 +2793,13 @@ </optional> </element> </define> + <define name="nvram"> + <element name="nvram"> + <optional> + <ref name="address"/> + </optional> + </element> + </define> <define name="memballoon"> <element name="memballoon"> <attribute name="model"> @@ -3280,6 +3287,9 @@ <optional> <ref name="memballoon"/> </optional> + <optional> + <ref name="nvram"/> + </optional> </interleave> </element> </define> diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 1643f30..acaec20 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -194,6 +194,7 @@ VIR_ENUM_IMPL(virDomainDevice, VIR_DOMAIN_DEVICE_LAST, "smartcard", "chr", "memballoon", + "nvram", "rng") VIR_ENUM_IMPL(virDomainDeviceAddress, VIR_DOMAIN_DEVICE_ADDRESS_TYPE_LAST, @@ -1560,6 +1561,16 @@ void virDomainMemballoonDefFree(virDomainMemballoonDefPtr def) VIR_FREE(def);

[libvirt] [PATCH] Change the tag name "num_queues" into "queues"

[libvirt] virNodeDevice APIs and VFIO

by Laine Stump

Yesterday for the first time I consciously noticed the virNodeDeviceDettach and virNodeDeviceReAttach APIs, and found that they are hardcoded to bind to/unbind from the pci-stub driver for qemu, and the "pciback" driver for Xen. If we want these APIs to be useful for VFIO, they will need to bind to the vfio driver instead, but there is currently no method in those APIs to specify which driver to bind to. I guess we could do this with new virNodeDeviceDetachFlags() and virNodeDeviceReAttachFlags() APIs which have a flag to indicate vfio, but before going to that trouble I'd like to know if these APIs are actually used or if they are deprecated (they don't seem to be of any use if the hostdev devices you're assigning have "managed='yes'" - as far as I can see, setting managed='yes' just makes the bind/unbind from the stub driver an automatic part of assigning/un-assigning the device to a guest). (Beyond that, this would be exposing a lower level of detail in the APIs than the original functions, and I'm not sure if it's appropriate - the choice of stub driver was previously hidden in each hypervisor driver).
