Mouse events
Hello,
I would like to ask if is there any way how to send mouse event to running
domain. I am looking for something like a method for handling keyboard
events(virDomainSendKey method). Is it implemented yet or is it future todo
item(when It will be released?)?
Thank for your answer

Snapshots
Hello,
I would like to ask what I am doing wrong and what is the best approach to
resolve this situation:
First of all I start virtual machine by virDomainCreateXML. In my
application I use libvncclient library that sends mouse events to this
running domain. I had some troubles with coordinates of mouse cursor but all
problem was solved when I added <input type='tablet'

domain reinitalization detection
Hello
I'm trying to find out how to detect if domain was destroyed and brought up between two time moments, let's call it reads.
So far the best approach I could find is to compare domain ID from previous and current read.
And this is my first question : is that reliable solution ? Or do you know any better ?
And related question is how to resolve virDomainPtr into domain ID ?

I guess that would require running my own polling thread, right ? I wanted to avoid that ...
Thanks for help

Thread-safety issues with vbox driver ?
Hi,
I'm experiencing weird things with the vbox driver when using multiple threads.
Following is the snippet of code I experience problems with
/*****************************************************/
#include <stdlib.h>
#include <stdio.h>
#include <pthread.h>
#include <libvirt/libvirt.h>

[PATCH libguestfs v3] lib: Handle slow USB devices more gracefully.
Libvirt has a fixed 15 second timeout for qemu to exit. If qemu is
writing to a slow USB key, it can hang (in D state) for much longer
than this - many minutes usually.
The solution is to check specifically for the libvirt EBUSY error when
this happens, and retry the virDomainDestroyFlags operation
(indefinitely).

Problem in getting memory statistics
Hello,
I need to get how much memory is used by a guest system, in order to
implement some monitoring function which tells me if the system is
overstressed.
I am currently using java apis and the binding which was suggested to me was
Domain.memoryStats();
This is a binding to int virDomainMemoryStats

printing domain information
how do i print the features of a domain from functions that return a domain object?
for instance mydomain =?virdomain=libvirt.virConnect.lookupByID(conn,domainid)
so mydomain is?virDomainPtr, which is?typedef virDomain * virDomainPtr
i am not sure on how to print the domain object features in python, such as name, disk size, etc

undefining and redefining a Domain
<resending as I don't think I was in the mailing list yet when I sent

Hello,
I'm facing some strange behavior, and I hope you can provide a
clarification.
Consider the following code:

[API reference] Are there XML-handling API to retrieve info directly from xml configure file
Hi, everyone
I'm writing a application using libvirt and need to query guest
os's virtual network interface usage, like bytes read or written
through a given interface. I know int
virDomainInterfaceStats(virDomainPtr dom, const char * path,
virDomainInterfaceStatsPtr stats, size_t size) is designed for my
purpose but I 'm not sure how I determine the second parameter path.

[PATCH v1 0/2] Implement guestfs_add_libvirt_dom.
This is only lightly tested at the moment.
For context see:
https://bugzilla.redhat.com/show_bug.cgi?id=1138203#c40
https://bugzilla.redhat.com/show_bug.cgi?id=1075143
https://bugzilla.redhat.com/show_bug.cgi?id=1075164
Note this is not a complete fix. At least one more libguestfs patch
is required (to implement virDomainPtr in the python bindings). Plus
a virt-manager patch.

Regarding Migration Statistics
Greetings,
I am writing a code using libvirt API to migrate VM between two physical
hosts *(QEMU/KVM) , *say some *n *number of times.

calculate the total migration time I am using something like this:

virDomainGetInfo() returns wrong domain state
Hi Team,
I have written below code to get the VM state at run time. I found, though the VM is in shut-off state, when I use the function virDomainGetInfo(); I get state as running. Could you please let me know what wrong I am doing. To know the actual VM state I used 'virsh list' and it clearly shows the VM is in shut-off state. Please find the log and code snippet below.
