About Libvirt Setmem&dommemstat Function
I have sent a similar email about this problem. But I did not describe carefully, so I would like to explain it in more details.
I am using 'virsh setmem' to ajust vm memory online. However, I don't know what is the lowerlimit that can be set to. And I try to use 'virsh dommemstat' to get 'unused' memory so that I can calculate the lowerlimit memory with this value, but

Re: Dynamically setting permanent memory libvirt-lxc
Eric, thank you for your response. Virsh memtune, setmaxmem and setmem won't survive a reboot. I'm hoping to find a solution that can survive reboot.

Is libvirt supported on Citrix Xenserver?
Hi,
I was finally able to connect to the xenapi hypervisor. However, once I connect to virsh and give a 'quit' command I get "* glibc detected *** virsh: double free or corruption (fasttop):". Please find below the actual memory dump.

Release of libvirt-0.9.0
As scheduled, libvirt 0.9.0 was tagged and pushed today, it's
available from FTP at:
ftp://libvirt.org/libvirt/
This is a large release w.r.t. the amount of features and changes,
and well worth bumping the middle version number. We are also getting
closer to a 1.0.0 release !
Features:
- Support cputune cpu usage tuning (Osier Yang and Nikunj A. Dadhania)
- Add public APIs for storage

adaptIntegral takes too much time
Hello Dear List members,
as you can see (and guess) from the code below

Error from using adaptIntegrate within a function that is then integrated
I want to measure the error in the estimation of a 2 dimensional density
function that is calculated using an integral but run into problems trying
to integrate with adaptIntegrate because the integrand also calls the
function adaptIntegrate. In particular I want
\int \hat{f}(x,y) - f(x,y) dx dy
where \hat{f}(x,y) = \int K(a,b, x, y) da db and in this simulation study I
know what the true value

cubature
Hi,
I am using adaptIntegrate from Cubature to do numerical integration on a
double integral with a 1 x 2 vector x.
Say the function is something simple to start like f(x)=x1*x2 and I wish to
integrate x1 over (0,365-x2) and x2 over (0,365)
f <- function(x) {(x[2])*(x[1])} # "x" is vector
int1<-adaptIntegrate(f, lowerLimit = c(0, 0), upperLimit = c(365-x[2], 365))

no callback on VIR_DOMAIN_EVENT_ID_BALLOON_CHANGE in 0.10.2
I'm trying to track balloon growth after issuing a setmem command to a KVM
guest with libvirt 0.10.2 and qemu-kvm 0.12.1.2 on CentOS 6.3. libvirt
0.10.2 was built from tar today and appears to be working fine. The guest
is running CentOS 6.3 as well.
Using the provided test programs under examples/domain-events/ in C and
Python, I'm not seeing VIR_DOMAIN_EVENT_ID_BALLOON_CHANGE ever

How lld invoke LTO or thinLTO and is there some cases and some method to get the step-by-step message for me to understand how LTO worked?
Hi:
I want to learn how LTO and thinLTO work? But I'm confused how lld invoked either library. How can I find it in lld. Should i be familiar with lld source code? And i also think if there is some easy test case and with step-by- step debugging or some log messages can help me learn this? Is there some method can do stuff like this?
Thank you very

Why a max mem setting?
Hi
I have just started to investigate the possibilities of resizing memory for my kvm virtual machines on the fly. It works just fine with virsh setmem and that's great. Now, what I'm wondering about is the <memory> directive in the xml domain definition. Why would I not just set that to the size of available RAM in the host machine? Am I missing some nuance or finesse to the

Integration in R
Hi R-users.
I'm having difficulty with an integration in R via
the package "cubature". I'm putting it with a simple example here. I wish
to integrate a function like:
f(x1,x2)=2/3*(x1+x2) in the interval 0<x1<x2<7. To be sure I tried it
by hand and got 114.33, but the following R code is giving me 102.6667.

changing memory size with virsh setmem - results only visible in domain, not on host
Hi,
i have a Linux domain (Ubuntu 14.04) where we like to be able to change the amount of usable memory.
We have a balloon device and statistics are switched in 5 sec. rhythm.
The domain shows very quickly changes (following top) when we change the memory size with setmem, but the host does not show changes in the use
of memory for the respective domain.
Is that expected behavior ?
Host is SLES
