[libvirt] We need this patch to mount all tmpfs file systems with the correct context.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Basically within a Secure Linux Container (virt-sandbox) we want all content that the process within the container can write to be labeled the same. We are labeling the physical disk correctly but when we create "RAM" based file systems libvirt is not labeling them, and they are defaulting to tmpfs_t, which will will not allow the processes to write. This patch labels the RAM based file systems correctly. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAlAFiTwACgkQrlYvE4MpobPA1ACghFq3nxmNmHP/WEq1vSwjtoin VFoAnAlxgPISuIPiAPSFUL0CjiiSXDzw =xFCU -----END PGP SIGNATURE-----

[libvirt] [PATCH v3] storage backend: Add sheepdog support
by Sebastian Wiedenroth 18 Jul '12

18 Jul '12

This patch brings support to manage sheepdog pools and volumes to libvirt. It uses the "collie" command-line utility that comes with sheepdog for that. A sheepdog pool in libvirt maps to a sheepdog cluster. It needs a host and port to connect to, which in most cases is just going to be the default of localhost on port 7000. A sheepdog volume in libvirt maps to a sheepdog vdi. To create one specify the pool, a name and the capacity. Volumes can also be resized later. In the volume XML the vdi name has to be put into the <target><path>. To use the volume as a disk source for virtual machines specify the vdi name as "name" attribute of the <source>. The host and port information from the pool are specified inside the host tag. <disk type='network'> ... <source protocol="sheepdog" name="vdi_name"> <host name="localhost" port="7000"/> </source> </disk> To work right this patch parses the output of collie, so it relies on the raw output option. There recently was a bug which caused size information to be reported wrong. This is fixed upstream already and will be in the next release.

[libvirt] [libvirt-glib] Fix *_new_from_xml
by Christophe Fergeau 18 Jul '12

18 Jul '12

For objects with a subtype 'type' attribute, when the _new_from_xml function was called, the 'type' attribute was forcefully set to the right value rather than checking that the passed-in value matches the type of the subclass we are trying to instantiate. This commit changes this, and returns NULL when the value of the 'type' attribute of the passed-in XML document does not match the expected type. --- libvirt-gconfig/libvirt-gconfig-domain-address-pci.c | 2 +- libvirt-gconfig/libvirt-gconfig-domain-address-usb.c | 2 +- libvirt-gconfig/libvirt-gconfig-domain-chardev-source-pty.c | 2 +- libvirt-gconfig/libvirt-gconfig-domain-chardev-source-spicevmc.c | 2 +- libvirt-gconfig/libvirt-gconfig-domain-controller-usb.c | 2 +- libvirt-gconfig/libvirt-gconfig-domain-graphics-sdl.c | 4 +--- libvirt-gconfig/libvirt-gconfig-domain-graphics-spice.c | 4 +--- libvirt-gconfig/libvirt-gconfig-domain-graphics-vnc.c | 4 +--- libvirt-gconfig/libvirt-gconfig-domain-interface-bridge.c | 4 +--- libvirt-gconfig/libvirt-gconfig-domain-interface-network.c | 4 +--- libvirt-gconfig/libvirt-gconfig-domain-interface-user.c | 4 +--- libvirt-gconfig/libvirt-gconfig-domain-timer-pit.c | 2 +- libvirt-gconfig/libvirt-gconfig-domain-timer-rtc.c | 2 +- 13 files changed, 13 insertions(+), 25 deletions(-) diff --git a/libvirt-gconfig/libvirt-gconfig-domain-address-pci.c b/libvirt-gconfig/libvirt-gconfig-domain-address-pci.c index 48e3872..5199b8a 100644 --- a/libvirt-gconfig/libvirt-gconfig-domain-address-pci.c +++ b/libvirt-gconfig/libvirt-gconfig-domain-address-pci.c @@ -67,7 +67,7 @@ GVirConfigDomainAddressPci *gvir_config_domain_address_pci_new_from_xml(const gc object = gvir_config_object_new_from_xml(GVIR_CONFIG_TYPE_DOMAIN_ADDRESS_PCI, "address", NULL, xml, error);

[libvirt] virDomainMemoryStats call
by Parakkal, Navin S 18 Jul '12

18 Jul '12

Hi, I'm using the API virDomainMemoryStats to fetch memory stats for a domain/guest on Fedora 16/RHEL 6.3 . I don't get these counters filled up VIR_DOMAIN_MEMORY_STAT_UNUSED, VIR_DOMAIN_MEMORY_STAT_ACTUAL_BALLOON,VIR_DOMAIN_MEMORY_STAT_AVAILABLE , VIR_DOMAIN_MEMORY_STAT_MAJOR_FAULT and VIR_DOMAIN_MEMORY_STAT_MINOR_FAULT. The version of libvirt 0.9.11 on Fedora 16 . How to get all the counters filled up ? Should I take a specific version of qemu or should I do some config settings so that these values are filled up ? P.S. Please copy me in reply Regards, Navin Parakkal HP Software

[libvirt] [PATCH] remote: Fix locking in stream APIs
by Jiri Denemark 18 Jul '12

18 Jul '12

Remote driver needs to make sure the driver lock is released before entering client IO loop as that may block indefinitely in poll(). As a direct consequence of not following this in stream APIs, tunneled migration to a destination host which becomes non-responding may block qemu driver. Luckily, if keepalive is turned for p2p migrations, both remote and qemu drivers will get automagically unblocked after keepalive timeout. --- src/remote/remote_driver.c | 40 ++++++++++++++++++++++++++++------------ 1 file changed, 28 insertions(+), 12 deletions(-) diff --git a/src/remote/remote_driver.c b/src/remote/remote_driver.c index 3314f80..acae5d0 100644 --- a/src/remote/remote_driver.c +++ b/src/remote/remote_driver.c @@ -3976,12 +3976,14 @@ remoteStreamSend(virStreamPtr st, VIR_DEBUG("st=%p data=%p nbytes=%zu", st, data, nbytes); struct private_data *priv = st->conn->privateData; virNetClientStreamPtr privst = st->privateData; - int rv = -1; - - remoteDriverLock(priv); + int rv; if (virNetClientStreamRaiseError(privst)) - goto cleanup; + return -1; + + remoteDriverLock(priv); + priv->localUses++; + remoteDriverUnlock(priv); rv = virNetClientStreamSendPacket(privst, priv->client, @@ -3989,9 +3991,9 @@ remoteStreamSend(virStreamPtr st, data, nbytes); -cleanup: + remoteDriverLock(priv); + priv->localUses--; remoteDriverUnlock(priv); - return rv; } @@ -4004,12 +4006,14 @@ remoteStreamRecv(virStreamPtr st, VIR_DEBUG("st=%p data=%p nbytes=%zu", st, data, nbytes); struct private_data *priv = st->conn->privateData; virNetClientStreamPtr privst = st->privateData; - int rv = -1; - - remoteDriverLock(priv); + int rv; if (virNetClientStreamRaiseError(privst)) - goto cleanup; + return -1; + + remoteDriverLock(priv); + priv->localUses++; + remoteDriverUnlock(priv); rv = virNetClientStreamRecvPacket(privst, priv->client, @@ -4019,9 +4023,9 @@ remoteStreamRecv(virStreamPtr st, VIR_DEBUG("Done %d", rv); -cleanup: + remoteDriverLock(priv); + priv->localUses--; remoteDriverUnlock(priv); - return rv; } @@ -4138,12 +4142,18 @@ remoteStreamFinish(virStreamPtr st) if (virNetClientStreamRaiseError(privst)) goto cleanup; + priv->localUses++; + remoteDriverUnlock(priv); + ret = virNetClientStreamSendPacket(privst, priv->client, VIR_NET_OK, NULL, 0); + remoteDriverLock(priv); + priv->localUses--; + cleanup: virNetClientRemoveStream(priv->client, privst); virNetClientStreamFree(privst); @@ -4167,12 +4177,18 @@ remoteStreamAbort(virStreamPtr st) if (virNetClientStreamRaiseError(privst)) goto cleanup; + priv->localUses++; + remoteDriverUnlock(priv); + ret = virNetClientStreamSendPacket(privst, priv->client, VIR_NET_ERROR, NULL, 0); + remoteDriverLock(priv); + priv->localUses--; + cleanup: virNetClientRemoveStream(priv->client, privst); virNetClientStreamFree(privst); -- 1.7.11.1
