[libvirt] [PATCH] Set the 'container_ttys' env variable for LXC consoles
by Daniel P. Berrange 16 Dec '13

16 Dec '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> Systemd specified that any /dev/pts/NNN device on which it is expected to spawn a agetty login, should be listed in the 'container_ttys' env variable.

[libvirt] [PATCH] Return right error code for baselineCPU
by Don Dugger 15 Dec '13

15 Dec '13

This Python interface code is returning a -1 on errors for the `baselineCPU' API. Since this API is supposed to return a pointer the error return value should really be VIR_PY_NONE. NB: I've checked all the other APIs in this file and this is the only pointer API that is returning -1.

by Umar Draz 14 Dec '13

14 Dec '13

Hi I am running libvirt 1.2.0 on ubuntu. The main purpose of this libvirt 1.2.0 is for glusterfs, now I can define glusterfs storage pool using virsh command, but when I tried to create the volume under the gluster storage pool, I got error. error: Failed to create vol from tt.xml error: this function is not supported by the connection driver: storage pool does not support volume creation. But according to this url http://libvirt.org/storage.html we can create the volume. Any body please help me. Br. Umar

[libvirt] [PATCH] event-test: Unregister close callback
by Michal Privoznik 14 Dec '13

14 Dec '13

When registering a close callback, the connection refcount is increased as the connection object is passed to the callback and hence we must prevent deleting it too soon. However, when closing the connection, the connection object is just unrefed. So whenever a connection with a close callback is closed, we end up with the connection object which has exactly one reference. Leaving the code as-is doesn't mean the end of the world as we know it, but why give a bad example? ==14531== 288 bytes in 1 blocks are still reachable in loss record 695 of 762 ==14531== at 0x4C2BDE4: calloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==14531== by 0x4E9FE09: virAllocVar (viralloc.c:558) ==14531== by 0x4EDBE45: virObjectNew (virobject.c:190) ==14531== by 0x4F71AAC: virGetConnect (datatypes.c:116) ==14531== by 0x4F78511: do_open (libvirt.c:1136) ==14531== by 0x4F7B3AC: virConnectOpenAuth (libvirt.c:1481) ==14531== by 0x4011D2: main (event-test.c:499) (and other leaks tied to virGetConnect()) Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- examples/object-events/event-test.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/examples/object-events/event-test.c b/examples/object-events/event-test.c index f872b9f..228a091 100644 --- a/examples/object-events/event-test.c +++ b/examples/object-events/event-test.c @@ -675,6 +675,8 @@ int main(int argc, char **argv) virConnectDomainEventDeregisterAny(dconn, callback8ret); } + virConnectUnregisterCloseCallback(dconn, connectClose); + VIR_DEBUG("Closing connection"); if (dconn && virConnectClose(dconn) < 0) { printf("error closing\n"); -- 1.8.5.1

[libvirt] [PATCH] qemu: always ask for -enable-fips
by Eric Blake 14 Dec '13

14 Dec '13

On a system that is enforcing FIPS, most libraries honor the current mode by default. Qemu, on the other hand, refused to honor FIPS mode unless you add the '-enable-fips' command line option; worse, this option is not discoverable via QMP, and is only present on binaries built for Linux. As far as I can tell, unconditionally using the option when it is available has no negative consequences (the option has no change to qemu behavior except when FIPS is enabled, at which point it cripples insecure VNC passwords which is the one thing that libvirt must not allow when FIPS is active).

[libvirt] [PATCH] Don't call virCgroupSetCpuShares with a zero value
by Ján Tomko 14 Dec '13

14 Dec '13

In the XML parser, a zero in the <shares> element is treated as if it was omitted completely. No value is written to the cgroups fs when the domain is started and the OS default is used. virDomainSetSchedulerParameters treated 0 as a valid value, which got changed to '2' by kernel. Treat 0 as 'not specified' instead, to be consistent with the XML and how other scheduler parameters deal with a 0 value, making it a no-op on live domains.
