[libvirt] [PATCHv6 0/6] Add virNodeGetCPUStats() API
by Minoru Usui
Hi,
This is v6 of virNodeGetCPUTimeParameters() API.
(This time, I rename it to virNodeGetCPUStats())
It returns cpu utilization or
cumulative cpu time of the node from /proc/stat since node boots up.
This patch only supports linux host.
Changes
v5->v6
- Rename API name to virNodeGetCPUStats()
- virsh nodecpustats subcommand returns raw/absolute cputime value by default,
and add --percent option for printing utilization.
v4->v5
- Rebase latest libvirt GIT tree.
v3->v4
- Rebase this patch like virDomainGetMemoryParameters() from v2 patches.
(drop v3 patches except virsh subcommand)
- Rename API name to virNodeGetCPUTimeParameters()
v2->v3
- Change user I/F. It is able to request what the user want by the @flags.
- Minor change of virsh nodecputime I/F.
v1->v2
- Change user I/F like virDomainGetMemoryStats()
- It can return either cpu utilization or cumulative cpu time of the node
depends on each driver.
Minoru Usui (6):
[v6] virNodeGetCPUStats: Expose new API
[v6] virNodeGetCPUStats: Define internal driver API
[v6] virNodeGetCPUStats: Implement public API
[v6] virNodeGetCPUStats: Implement remote protocol
[v6] virNodeGetCPUStats: Implement virsh support
[v6] virNodeGetCPUStats: Implement linux support

[libvirt] [PATCH] security: plug regression introduced in disk probe logic
by Eric Blake
Regression introduced in commit d6623003 (v0.8.8) - using the
wrong sizeof operand meant that security manager private data
was overlaying the allowDiskFOrmatProbing member of struct
_virSecurityManager. This reopens disk probing, which was
supposed to be prevented by the solution to CVE-2010-2238.

[libvirt] remote generator: Legacy support for hyper to long mappings
by Matthias Bolte
This can be considered as a v2 for hyper annotation patch [1]. Dan
argued that hyper-to-long mapping is considered as legacy and hyper
should be mapped to long long for all new APIs. Therefore, he voted
against the longlong annotation, because this should be the default
anyway.
I removed the longlong annotations from the original patch. This
results in version-A of the attached patch 0001. But this optional
annotation makes the parser more complex. One of the reasons for
annotating things in the .x is to have single place to define a new
procedure. But as the long/longlong annotation only affect exiting
procedures and will not be added to new ones it's much simpler to
store this information in the generator itself. This information it is
fixed and will not change anymore. This is implemented in version-B of
the attached patch 0001. I favor version-B, what's your opinion on
this?
Attached patch 0002 extends the apibuild script to allow the usage of
long for the same fixed set as in the remote generator only. It
reports an error when new functions or structs use long instead of
longlong.

Convert openvzLocateConfFile to a replaceable callback to allow
testing the config file parsing without rewriting the whole OpenVZ
config parsing to a more testable structure.
Also ignore the openvzutilstest binary.

[libvirt] virsh version problem with remote connection
by Matthias Bolte
virsh version does basically this
hvType = virConnectGetType(...)
virGetVersion(..., hvType, ...)
[...]
Assuming a remote connection virConnectGetType calls the remote driver
that returns the type of the underlying driver on the server side, for
example QEMU. Then virGetVersion compares hvType to a set of strings
that depend on configure options and returns LIBVIR_VERSION_NUMBER in
most cases. Now this fails in case libvirt on the client side is just
compiled with the remote driver enabled and the server side has the
actual driver such as the QEMU driver. It just happens to work when
the actual driver is compiled in on client and server side. But that's
not the case here.
freebsd# ./tools/virsh -c qemu+tcp://192.168.178.22/system version
Compiled against library: libvir 0.9.2
error: failed to get the library version
error: this function is not supported by the connection driver: virGetVersion
This is not FreeBSD specific, happens on Windows as well due to the
similar drivers configuration. The problem is that virConnectGetType
returns QEMU, but virGetVersion on the client side only accepts Remote
as hvType due to all other drivers being disabled on the client side.
I'm not sure how to fix this properly, does anyone have some idea?

[libvirt] [PATCH] util: Fix incorrect error in PCI functions.
by Osier Yang
Substitute VIR_ERR_NO_SUPPORT with VIR_ERR_INTERNAL_ERROR. Error
like following is not what user want to see.
error : pciDeviceIsAssignable:1487 : this function is not supported
by the connection driver: Device 0000:07:10.0 is behind a switch
lacking ACS and cannot be assigned
