[libvirt] cpu_map data access for libxl driver
by Cedric Bosdonnat
Hi Jiri, all,
As I mentioned earlier today on IRC, I have started implementing CPU configuration
support for libxl driver.
libxl expects a string definition the state of all the feature (easy to create), but also
the numeric values for the CPU family and model. virCPUDef holds the name as a string, but
not the numeric values though there are stored in the cpu_map.xml.
For what libxl expects, search for 'cpuid=' in this man page:
http://xenbits.xen.org/docs/unstable/man/xl.cfg.5.html
Any idea how to get those values from the libxl driver?

[libvirt] [PATCH 0/4] virsh: Provide better auto-completion
by Nishith Shah
This series of patches are meant to improve existing auto-complete
functionality in virsh.
The first patch breaks vshCmddefOptParse into two smaller functions, for
use later in the third patch.
The second patch simply changes the types of variables used in existing
readline generators.
The third patch introduces quiet mode for the functions vshCmddefGetOption
and vshCommandStringGetArg.
The fourth patch introduces vshReadlineParse, which uses existing parsing
functions and borrows from vshCommandParse to quite some extent and provides
better auto-completion.
Nishith Shah (4):
virsh: Break vshCmddefOptParse into helper functions
virsh: Fix variable types in readline generators
virsh: Add option to suppress error in various functions
virsh: Introduce vshReadlineParse for improved auto-completion

[libvirt] [PATCH 00/10] Test persistent device attachment
by Tomasz Flendrich
This patch requires two other patches:
https://www.redhat.com/archives/libvir-list/2016-July/msg00264.html
https://www.redhat.com/archives/libvir-list/2016-July/msg00202.html
In qemu_driver.c, two functions were split to have less responsibility.
They were also modified so that they could be used in qemuhotplugtest.
Now instead of running different functions to attach different device
types, a generic function is run. Hopefully this will result in more
device types tested in the future.
Suggestions on how to name these two new functions are very welcome.
In the future, if one uses the following command:
virsh attach-device --live --config
the new device will have the same address assigned in both live
and config domain. To make sure that everything will work properly
after making these changes, I reworked qemuhotplug.c to work with
attaching devices to persistent domains.
So far, there is only one test for persistent attachment. I will
add more testcases as soon as I hear some feedback on these changes.
qemuhotplugtest.c should first be modified anyway, so that the three
xmls's filenames (basis domain xml, device xml, expected xml) are stated
explicitly instead of being calculated. This will allow for more
flexibility in testing and less xml files duplicates.
Tomasz
Tomasz Flendrich (10):
Change parameters to qemuDomainAttachDeviceLive
Remove an unnecessary variable
Split qemuDomainAttachDeviceFlags in two
Narrow down a parameter
Split qemuDomainDetachDeviceFlags in two
Make qemu attach/detach functions public
Narrow down a parameter to function
Use more generic functions in qemuhotplugtest
Make qemuhotplugtest work with persistent domains
Add a persistent attachment testcase

[libvirt] [PATCH] qemu: report vcpu state in virDomainGetVcpus
by Boris Fiuczynski
From: Viktor Mihajlovski <mihajlov(a)linux.vnet.ibm.com>
Currently, the virVcpuInfo returned by virDomainGetVcpus() will always
report a state of VIR_VCPU_RUNNING for each defined domain vcpu even if
the vcpu is currently in the halted state.
As the monitor interface is in fact reporting the accurate state, it is
rather easy to transport this information with the existing API.
This is done by
- adding a new state of VIR_VCPU_HALTED
- extending the monitor to pass back the halted state for the vcpus
- adding a new array to the private domain object reflecting the halted
state for the vcpus and update it along with the vcpu pids array
- modifying the driver code to report the vcpu state based on the halted
indicator
- extending virsh vcpuinfo to also display the halted state
- modifying the monitor_json testcase
The vcpu state is however not recorded in the internal XML format, since
the state can change asynchronously (without notification).
