Support for Hyper-V
Hi,
I would like to know if libvirt support Hyper-V deployed in Windows 2012
server. Does libvirt talk to Hyper-V using the REST API provided by
Microsoft (where SCVMM & SPF are deployed)?
>From the web site, I see that libvirt support only "Hyper-V 2008 R2"
Many thanks in advance.

[LLVMdev] post-dominance frontier
In the literature (see below for a reference), when a dominance frontier
is computed, it is computed from a CFG that contains a dummy entry node
and dummy exit node. Further, those dummy nodes are potential members
of the (post-)dominance frontier for a given basic block. In LLVM, I
could not figure out a way to determine if the dummy entry node is a
member of the post-dominance frontier of

The accurate CPU usage of a domain?

I want to get a relatively accurate cpu usage of a domain. I have a few questions about virDomainGetInfo: struct virDomainInfo{ unsigned char state : //the running state, one of virDomainState unsigned long maxMem :// the maximum memory in KBytes allowed unsigned long memory :// the memory in KBytes used by the domain unsigned short nrVirtCpu :// the number of virtual CPUs for the

[LLVMdev] dominator, post-dominator and memory leak
Hi all,
I have been writing a pass to heapify some alloca's (it is
pessimistization, not optimization). For example, in the following control
flow graph, there is a call to malloc inserted in block BB12. In order to
avoid memory leak, free's are needed. The free cannot be inserted in BB23
because BB23 is not dominated by BB12. There are two ways to go I can think
of here. One way is to

That crossed my mind a few minutes later. : )
If you're interested, PRE.cpp existed last at r25315. It calculates the

[LLVMdev] dominator, post-dominator and memory leak
PRE normally uses a latest placement algorithm to do something of the sort.
I don't know about GVN/PRE, but older version of PRE might have it.
Just placing the calls to free at the predecessors (dominated by BB12) of
the dominance frontier of BB12 seems to work, however. Is there anything
wrong with this?

[LLVMdev] dominator, post-dominator and memory leak
Hi Henrique,
I have tried using -mergereturn and inserting a free into the predecessors
of dominance frontier of malloc block and it caused double free. It is
possible for multiple free's to be inserted on the path from malloc to an
exit. For example, in the following CFG:
BB10 (malloc)
/ \
BB11 BB12

[LLVMdev] dominator, post-dominator and memory leak
Bill,
Just in case this is relevant for you: If you're working with C++ code, or otherwise have any functions that might throw exceptions, you might also need to catch those exceptions in order to free the allocated memory. This will involve looking for calls to functions that mayThrow(), changing their calls to invokes, and freeing the memory before resuming the unwinding.

xm top
Hello everybody!
I´d like to know where "xm top" gets its information from. I want to get
those informations (cpu-load, mem etc. from the domUs) and display them
with php in a browser. So are the informations stored and updated in a
textfile or something like that? Can anybody help me with this?

Network filters with clean-traffic not working on Debian Stretch
Hello,
I'm recently stumbled over the libvirt network filter capabilities and
got pretty excited. Unfortunately I'm not able to get the the
"clean-traffic" filterset working. I'm using a freshly installed Debian
Stretch with libvirt, qemu and KVM.
My config snippet looks as follows:

Disk and Network Statistics for a Specific Interval
Hi,
virDomainInterfaceStats - This function returns network interface stats for
interfaces attached to the domain.
virDomainBlockStats- This function returns block device (disk) stats for
block devices attached to the domain.
Based on which time interval these function returns values.
Is it cumulative from the vms uptime..?
OR average ...?
How can I get the average statistics of Disk and

[RFC] Saturating left shift intrinsics
Hello,
This is an RFC for adding intrinsics which perform saturating signed/unsigned left shift.
There is currently a patch on Phabricator here:
https://reviews.llvm.org/D83216
The intrinsics are of the form
i32 @llvm.sshl.sat.i32(i32, i32)
i32 @llvm.ushl.sat.i32(i32, i32)
<4 x i32> @llvm.sshl.sat.v4i32(<4 x i32>, <4 x i32>)

Re: Network filters with clean-traffic not working on Debian Stretch
Dear Yalang,
that did the trick. If I look in the NAT table of the bridge I can see
the generated rules. Probably wouldn't have though about that ever.
Thanks a lot!

Getting nwfilter to work on Debian Wheezy
Hi,
I'm trying to configure nwfilter for KVM, but so far I haven't managed
to figure out a working configuration.
Network setup: The dom0 (Debian 7.1, kernel 3.2.46-1, libvirt 0.9.12) is
connected via eth0, part of the external subnet 192.168.17.0/24, and has
an additional subnet 192.168.128.160/28 routed to its main address
192.168.17.125.
The host's subnet is configured as bridge
