Although the migrate command is blocking, there is nothing stopping you from opening up a second connection to the

Re: Programmatically force shutdown a guest: possible?
Yes, you are right. Listen, as the documentation is not very exaustive, can you explain briefly to me how a guest agent works? After installing it via the apt-get on the hypervisor (I am using ubuntu as host system) how can I create a script which would do this? That is waiting for an acpi signal and actually shut down the guest. And what other operation can you actually do with a guest agent? I

Programmatically force shutdown a guest: possible?
I am looking at the shutdown method, but if the guest system is a desktop system, like for example ubuntu, it just has the effect to show a box prompting the user for a shutdown/reboot/ and such. I could enter the guest and change this default behaviour and it actually works..but I'd like for a way to send a shutdown command without doing so. Is it possible?

Live migration (kvm) not working if any I/O operation is in progress
Hello, I'd like to know if this is an hypervisor related problem or a libvirt one. I did this experiment: on VM I started watching a video on youtube. While video was in progress I started migration. Migration did not complete until video was not finished. I did another experiment: I installed a web server on VM. I then started an httperf stress test. As before migration did not complete

"connection refused", but server is listening
netstat -lptu gives me tcp6 0 0 [::]:16514 [::]:* LISTEN 1314/libvirtd so the server is correctly listening on interfaces. My /etc/libvirt/libvirtd settings are defaulted. My /etc/default/libvirt-bin has "-d -l" options so server is listening. If I do virsh -c qemu://143.225.229.190/system (that is my ip or an ip belonging to my network) I

FCR1: Syslinux boot disk after Kernel Update
Hi, I'm running fedora core rel. 1 on a dual system, using syslinux on a floppy disk as boot manager to start fedora. However, after up2date, I can't start fedora with the new kernel, as syslinux probably points to the old one. Kernel installation was done automatically via rpm (up2date online), but it didn't change syslinux parameters. What do I need to change in syslinux config

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 (virDomainPtr<http://libvirt.org/html/libvirt-libvirt.html#virDomainPtr>dom,

Set a domain name instead of an ip address into tls certificate
I tried to set cn=myMachine instead of cn=192.168.1.x and...everything frezees! virsh -c qemu://.../system tries to connect forever. You really need static ip addresses in the cn field?? I think this is an HUGE bug: you are saying to me that each time I change network or ip (because, dear sirs, dhcp exists) I have to generate a whole new couple of certificates?? I hope it is not the case....

Re: "connection refused", but server is listening
Another strange thing. I tried, in order to solve this, to put my hostname as listening address. I started with the ip, 192.168.2.2, and it works. I then decided to use the domain name, pasquale-Dell, but the socket is not created. Looking into logs it seems it tries to resolve the name, without success. After a lot of tries it just decides to give up. However, in file /etc/hosts the resolution is

Problems with tls connection when ran with user privileges
I set up my certificates, ca client and server, as described in your documentation: http://wiki.libvirt.org/page/TLSCreateServerCerts. I followed it step by step so it must be ok. However, when I run virsh -c qemu://192.168.1.2/system and I try a command like list --all I get: error: impossible connect to the hypervisor errore: no valid connection errore: Unable to set x509 CA certificate:

Designing libvirt client
Hi, I have a VMM application using a homegrown client for communicating with hypervisor. I am planning to migrate to libvirt because of the blocking nature of the calls. After going over the architecture, I would like to have a few doubts clarified 1) Should my application be necessarily multi-threaded in order to make use of the non-blocking calls in libvirt. [Are overlapping methods mainly used

Live migration process in src/qemu_driver.ca
​Hello, I have been trying to track different phases of a live migration process. I am using libvirt ​with qemu-kvm. I am issuing migration commands using virsh. Now, I want to measure the time spent in each phase of live migration, e.g., pre-copy and stop-copy. I stumbled upon the file qemu_driver.c.
