similar to: 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

Hello Yesterday, i brought linksys PAP2 and have success with that. The only thing that does not go well is the music on hold.

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

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.

Hi , Is there anyway to get uuid info inside a lxc container which is created by libvirt_lxc? For kvm, we can use dmidecode or lshw to get this info inside vm. Is there any tools to do this thing for libvirt lxc? Thanks for any help~ -- ------------ Jackie Best Regards

Hi all, I am trying to bring up lxc's using Libvirt JAVA API. I do the following: conn = Connect("lxc:\\\") xml_config = "<domain> .... <\domain>" dom = conn.domainCreateXML(xml_config, 0) dom.create() Using the above code, I am able to start a domain but the domain is not visible within the "lxc" list, i.e when I use the command "lxc-ls

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

Hi all I have CentOS Linux release 7.0.1406, libvirt 1.2.7 installed. Just after create and start inside LXC container present cgroups. Example for memory: [root@ce7-t1 /]# ls -la /sys/fs/cgroup/memory/ total 0 drwxr-xr-x 2 root root 0 Sep 15 17:14 . drwxr-xr-x 12 root root 280 Sep 15 17:14 .. -rw-r--r-- 1 root root 0 Sep 15 17:14 cgroup.clone_children --w--w--w- 1 root root 0 Sep 15

Hi all Each lxc container on node have mounted tmpfs for cgroups tree: [root-inside-lxc@tst1 ~]# mount | grep cgroups cgroup on /sys/fs/cgroup/cpu,cpuacct type cgroup (rw,nosuid,nodev,noexec,relatime,cpuacct,cpu) cgroup on /sys/fs/cgroup/cpuset type cgroup (rw,nosuid,nodev,noexec,relatime,cpuset) cgroup on /sys/fs/cgroup/memory type cgroup (rw,nosuid,nodev,noexec,relatime,memory) cgroup on

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. This

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

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

Currently I have a RH6.1 host with selinux enabled On this I am running a LXC container with ubuntu (without selinux) with OpenSSH_5.3p1 Debian-3ubuntu4, OpenSSL 0.9.8k 25 Mar 2009 when I try to do a ssh connection to the lxc container I get : ... debug1: Next authentication method: password root at 192.168.2.11's password: debug1: Authentication succeeded (password). debug1: channel 0: new

Hi all. Has someone success story with using autofs + nfs inside libvirt LXC container ? In my case nfs client and server in lxc work just fine, but with autofs hang on system call state(). I use CE7_64 on nodes and inside container with libvirt 1.2.18 May be I must set some of capabilities in <feature> (http://man7.org/linux/man-pages/man7/capabilities.7.html) ? I try only CAP_SYS_ADMIN
