Re: Starting processes inside VMs using Libvirt?
Thank you Eric, I am using KVM: qemu.. I'll try to see how I can use qemu-guest-agent.. If you have links to examples on how to start with it let me know please. Consider the following simple scenario.. I am using KVM to run several VMs; one of OSs in the guests is Windows XP. I want to send to it something from the Hypervisor level, e,g text,parameters,etc so that it will be displayed in

How to monitor a lxc container started by libvirt_lxc from inside ?
Hi Guys, When I created a lxc container by libvirt, I logged into the lxc container and noticed that info under /proc/ dir did not match the lxc container resource. Is the /proc dir in lxc container just showing the same thing as the lxc host? If I want to monitor the realtime resource usage inside the lxc container, What should I do? -------------- Best regards! GuanQiang 2013-07-23

Hostname inside lxc container
Hi all, I have installed a CentOS6 lxc guest under a Debian 8.x LXC host. All it is working ok but I can't change the hostname for the centos6 lxc container (it is using the same hostname from Debian host). I have modifyed HOSTNAME under /etc/sysconfig/network and /etc/hosts file, but it doesn't works. Do I need to change anything else?? Thanks.

Dynamically setting permanent memory libvirt-lxc
I'm trying to permanently change memory allocation for a libvirt-lxc domain. So far I tried changing memory in memory.limit_in_bytes under /cgroup/memory/libvirt/lxc/<container>/.  This didn't help. It appears that libvirt is not reading changes in cgroup. My requirements are 1) Be able to dynamically change memory of a LXC domain without reboot 2) The memory change must survive

Host loses network connectivity when starting containers
I have hit a problem running libvirt based containers in a CentOS 7 based host, with the extra wrinkle that my host is an EC2 instance in AWS. Ultimately everything works as advertised, and I can launch instances that host multiple libvirt lxc containers without problems, with one caveat: About one time in ten when the containers are started, the instance loses all network connectivity.

Check memory inside a container
Hi all, I'm new to LXC and libvirt. I have created a LXC container using libvirt. In domain XML file I have mentioned "memory" and "current memory" as 256 MB. Now I want to check the memory inside the container, but whenever I run top command or try to cat /proc/meminfo, it shows host machine's memory which is 3GB. So is there any command by which I can check

Ability of a VM to detect Libvirt events.
Hi there, Let's assume a libvirt event occurred on a VM, i.e an event like pause VM or reboot VM or any other libvirt event. Can the VM determine that such event was originated by libvirt? ---or in a more general term by the hypervisor? If yes, how can this be done in theory? Thanks in advance, Regards, Taimur
